SECTION 2.0 PLANNING AND DESIGN CRITERIA<br />
TNB in developing the connection system or supply infrastructure needs to satisfy a set of planning and design criteria<br />
which are described in this section.<br />
2.1 STEADY-STATE SUPPLY VOLTAGE PERFORMANCE<br />
(a)<br />
Steady-State Voltage Fluctuation under Normal Condition<br />
Under normal condition, when all circuit elements are in service, the distribution network including<br />
the points before the consumer metering must be planned to be maintained as is table 2-1 below:-<br />
Table 2-1: Steady -state voltage level fluctuation limits under normal conditions<br />
Voltage level<br />
% variation<br />
415V and 240V -10% & +5%<br />
6.6kV, 11kV, 22kV,33kV +/- 5%<br />
132kV and 275kV -5% & +10%<br />
(b)<br />
Steady-State Voltage Fluctuation under Contingency Condition<br />
Under contingency condition, when one or more circuit elements are on outage, the power frequency<br />
steady-state voltage at all points in the distributor’s distribution system including the points before the<br />
consumer metering must be planned to be maintained as follows:<br />
Table 2-2: Steady-State Voltage Fluctuation Limits under Contingency Condition<br />
Voltage level<br />
% variation<br />
415V and 240V +/- 10%<br />
6.6kV, 11kV, 22kV,33kV +10 & -10%<br />
132kV & 275kV +/- 10%<br />
2.2 SUPPLY SECURITY LEVEL<br />
Supply security of a distribution system network defines the availability of supply to consumers following the occurrence<br />

For supplies to consumers at voltage levels of 6.6kV, 11kV, 22kV and 33kV, large part of the network are generally<br />
designed to facilitate an average supply restoration of less than 4 hours. For supplies at 240V and 415V, the restoration<br />
period may vary beyond 4 hours depending on the type of network fault.<br />
2.2.3 Request for Higher Supply Security Level<br />
However, TNB can design the supply scheme to meet higher security level requirement of individual consumer or group<br />
of consumers. All additional costs involved in providing the higher security level shall be borne by the consumer.<br />
2.3 POWER QUALITY<br />
2.3.1 Power Quality Requirements<br />
2.3.1.1 The electromagnetic disturbance covers the following phenomena:<br />
a. Voltage fluctuations and flickers<br />
b. Harmonics up to order of 50 th<br />
c. Voltage dips and short supply interruptions<br />
d. Voltage unbalance<br />
e. Inter-harmonics up to 50 th<br />
f. Voltage distortions at higher frequencies (above 50 th harmonics)<br />
g. Transient overvoltages<br />
h. Power frequency variation<br />
i. Dc components<br />
j. Mains signaling<br />
30 TENAGA<br />
NASIONAL B E R H A D
For the purpose of this guideline, Power Quality is defined as the degree to which the voltage at the point<br />
of connection to the consumer of the Distribution Network is maintained to be Sinusoidal at Rated Voltage<br />
Magnitude and Frequency. In this guideline only items a to d are considered.<br />
2.3.1.2 This section specifies the Power Quality requirements of the electricity supply to be delivered to the consumers<br />
in the TNB distribution system in terms of voltage and frequency to be within specific limits so that the consumer<br />
s’ equipment directly connected to the TNB distribution system can operate safely within its design performance<br />
without suffering undue damage or breakdown. Likewise this guidelines shall be complied with by all consumers<br />
connected and who intend to be connected to the TNB distribution system.<br />
2.3.1.3 In order to achieve the required Power Quality, these guidelines will be used by TNB in planning, developing,<br />
maintaining and operating the distribution system and in connecting Distributed Generation and Demand to the<br />
distribution system.<br />
2.3.1.4 In cases where, the nature and operation of the new types of plant and equipment to be connected to the<br />
distribution system is perceived to be likely to cause problems to customers connected to the System, but not<br />
fully covered by this guidelines, expert advice will be sought to ensure the appropriate remedial measures are<br />
put in place.<br />
2.3.2 Scope<br />
2.3.2.1 This guidelines covers most of the power quality related phenomena generated by various types of plant and<br />
equipment connected to the distribution system as well as those generated by the transmission system. In each<br />
particular case the Distribution Power Quality that should be maintained is indicated together with the remedial<br />
approach and responsibilities of parties.<br />
2.3.3 Voltage Dips/Sags<br />
2.3.3.1 This guidelines does not specifically cover the requirements for transient phenomena which can affect the<br />
voltage level known as voltage “dip” or “sag” and “swell” usually experienced during system faults and the<br />
subsequent recovery period, which can adversely affect some customer equipment sensitive to such changes.<br />
Currently, there is no local or international guidelines that has been established to specify requirements of the<br />
supply voltage to the consumers with respect to the magnitude and duration of voltage dips and swells.<br />
TENAGA<br />
NASIONAL B E R H A D<br />
31
2.3.3.2 Guidelines and guides that exist with respect to voltage dips and swell are those that describe the environment in<br />
which the sensitive voltage equipment may experience which include typical number of voltage sag experiences<br />
and their duration. The main purpose of such guidelines is to ensure that equipment designed to be connected to<br />
the distribution systems to be compatible with the supply voltage performance in terms of various power quality<br />
problems including voltage sags.<br />
2.3.3. Malaysian Standard MS 1760:2004 760:00 “Guides on Voltage Dips and Short Interruptions on Public Electric Power<br />
Supply Systems” contains definitions and descriptions of voltage sags and short interruptions. MS1760:2004 is<br />
based on IEC 61000-2-8 with some limited data on the characteristics for Malaysia. The purpose of the Guides<br />
is to discuss voltage dips and short interruptions primarily as phenomena observed on public supply systems and<br />
its effects on voltage sensitive equipment receiving supply from such systems.<br />
2.3.3.4 There exist standards on immunity of equipment to supply voltage fluctuations and distortion with defined<br />
magnitude and duration of voltage dips and harmonics. IEC 61000-2 series of guidelines set out the supply<br />
characteristics e.g. IEC 61000-2.8 as indicated above. IEC 61000-3 series of guidelines sets out the compatibility<br />
levels which should be achieved when designing electrical equipment which may give rise to voltage fluctuations<br />
and harmonic distortion and when connecting such equipment to the distribution system, which will give<br />
immunity to interference to similar equipment connected to the distribution system. MS IEC 61000-4-11 & MS<br />
IEC 61000-4-34 series of standards specifies test methods.<br />
2.3.3.5 Some equipment suppliers and trade organisations also specify the immunity levels for certain types of equipment<br />
for example Semiconductor Industry Guidelines SEMI F47, Computer and Business Equipment Manufacturing<br />
Association CBEMA Compatibility Guidelines.<br />
2.3.3.6 TNB shall upon request from any customer advise the consumer having connected voltage sensitive loads<br />
or intending to connect voltage sensitive loads in their installation to take into account the short duration<br />
electromagnetic disturbance phenomena for selecting equipment with proper maximum intrinsic immunity.<br />
2.3.4 Voltage Step Change<br />
2.3.4.1 Limits of voltage changes due to Load, frequent and infrequent operational switching of Load both by TNB and<br />
the consumer are defined table 2.3.4.1. These limits are based on UK’s Engineering Recommendation P2 P2 on<br />
“Planning Limits for Voltage Fluctuations Caused by Industrial, Commercial and Domestic Equipment in the<br />
United Kingdom”, 1989.<br />

2.3.5 Voltage Fluctuations and Flicker<br />
2.3.5.1 The limits of Flicker that are acceptable on the distribution system are in accordance with the “Engineering<br />
Recommendation P28, Issued by The Electricity Council of UK in 1989 entitled Planning Limits for Voltage<br />
Fluctuation Caused by Industrial, Commercial and Domestic Equipment in the United Kingdom”. TNB uses the<br />
procedures contained in this document to plan the connection of Fluctuating Loads and applies the limits therein<br />
in measuring and monitoring the levels of Flicker at such points of connection.<br />
2.3.5.2.2 In accordance with the “Engineering Engineering Recommendation P2”, P2”, voltage fluctuations at a Point of Common<br />
Coupling with a fluctuating Load directly connected to the Distribution System shall not exceed:<br />
(a) % of the voltage level for step changes, which may occur repetitively. Any large voltage excursions other<br />
than step changes or less frequent step changes may be allowed up to a level of 3% provided that this<br />
does not constitute a risk to the distribution system or, in TNB’s view, any other party connected to the<br />
distribution system.<br />
(b) The planning limits for the Short and Long Term Flicker Severity applicable for Fluctuating Loads connected<br />
to the distribution system are as set out in the table below.<br />

2.3.5.3 In connecting a Fluctuating Load at a particular point or Point of Common Coupling it is necessary to assess the<br />
total Flicker due to the Fluctuating Load itself and the background Flicker measured at that point. In assessing<br />
the total Flicker TNB shall use the so called “RSS Rule”. This assessment is carried out by the RSS Rule by<br />
obtaining the sum of the squares of the Flicker from the Fluctuating Load and the background Flicker, with the<br />
square root of this sum yielding the total assessed Flicker at that Point of Common Coupling due to the specific<br />
Fluctuating Load and the background Flicker at that point.<br />
2.3.5.4 Connection of more than one Fluctuating Load at the same Point of Common Coupling or addition of further<br />
Fluctuating Load at the same location is carried out on a “first come first served” basis on the distribution system.<br />
This means that whilst the first Fluctuating Load may be within the allowable Flicker limits and not require<br />
any Flicker mitigation or compensation equipment, the second Fluctuating Load which may cause violation<br />
of Flicker limits will be obliged to invest in appropriate Flicker mitigation or compensation equipment. At<br />
the planning stage, in carrying out the assessment of the total Flicker due to more than one Fluctuating Load<br />
connecting at a particular Points of Common Coupling, TNB shall use the methodology described in P28.<br />
2.3.5.5 In assessing the level of Flicker due to a Fluctuating Load at the planning stage the assessment will be carried<br />
out at a realistic System operating condition giving the minimum number of connections with which that point<br />
on the System can be operated within normal voltage limits and following Secured Contingency Events. This<br />
condition shall be considered as representative of the type of System conditions under which the Flicker due to<br />
a Fluctuating Load will be at its highest value as the voltage fluctuations due to the Fluctuating Load will be at<br />
their highest level under such conditions.<br />
34 TENAGA<br />
NASIONAL B E R H A D
2.3.5.6 If under the operating conditions described in 2.3.5.5 the Flicker due to a Fluctuating Load exceeds the limits<br />
then Flicker compensation, which will reduce the Flicker to an acceptable level shall be installed. For the<br />
avoidance of doubt the acceptance Criteria for Flicker is the 95% values of Short and Long Term Flicker<br />
Severity i.e., P st<br />
and P lt<br />
will be below the limits specified in table 2.3.5.2. Here the 95% values mean the values<br />
of Flicker Severity measured and observed during 95% of the total observation period. The System overall<br />
performance yardstick for the level of Flicker reduction to be achieved shall be based upon enabling connection<br />
of other similar Fluctuating Load and/or permitting for future extension and development of the location with<br />
further Fluctuating Load installations. The Flicker compensation method and equipment to be used shall be<br />
of a type that does not cause resonance problems with the existing and intended future developments of the<br />
distribution system.<br />
2.3.5.7 If the permissible Flicker limits cannot be met even with installation of Flicker compensation at a particular<br />
Points of Common Coupling at a particular System voltage level then connection of the Fluctuating Load at a<br />
higher voltage level or elsewhere in the System shall be considered. The connection point of choice will need<br />
to have to experience lower voltage fluctuations than the first connection point considered under the operational<br />
conditions in 2.3.5.5.<br />
2.3.6 Harmonics<br />
2.3.6.1 All plant and equipment connected to the Distribution System, and that part of the TNB distribution system at<br />
each connection site, should be capable of withstanding the following distortions of the voltage waveform in<br />
respect of harmonic content. The maximum total levels of Harmonic Distortion at any connection point on the<br />
distribution system from all sources under both planned outage and Secured Contingency Event conditions,<br />
unless abnormal conditions prevail, shall not exceed:<br />
(a) at 33kV and 22kV, a Total Harmonic Distortion of 3% with no individual harmonic voltage greater than that<br />
shown in the tables X;<br />
(b) at 11kV and 6.6kV, a Total Harmonic Distortion of 4% with no individual harmonic voltage greater than that<br />
shown in the tables Y;<br />
(c) at 415V and below, a Total Harmonic Distortion of 5% with no individual harmonic voltage greater than that<br />
shown in the tables Z;<br />

distortion levels for the connection of each non-linear Load to the Distribution System. TNB will verify the<br />
results of the assessments.<br />
2.3.6. Consumers shall ensure that the Immunity Level of their plant and Apparatus is compatible with the<br />
electromagnetic disturbances present on the System including harmonics.<br />
2.3.6. .4 In assessing the level of harmonic distortion and individual harmonic levels at the planning stage, the assessment<br />
will be carried out at a realistic system operating condition giving the minimum number of connections with<br />
which that point on the system can be operated within normal voltage limits and following secured contingency<br />
events. This condition shall be considered as representative of the type of system conditions under which the<br />
harmonic distortion and individual harmonic levels will be at their highest level.<br />
2.3.6.5.5 If under the operating conditions describes in ..6. 2.3.6.1 (a) (a) the harmonic distortion and individual harmonic levels<br />
due to the load exceed the limits then harmonic filters which will reduce the harmonics to an acceptable level<br />
shall be installed to bring the levels within limits. The system overall performance yardstick for the level of<br />
harmonic reduction to be achieved shall be based upon enabling connection of other similar harmonic producing<br />
load and/or permitting for future extension and development of the location with further harmonic producing<br />
load installations.<br />
2.3.6.6.6 The planning limits of harmonics that are acceptable of the distribution system are in accordance with MS<br />
IEC 61000-3-6 “ Assessment of emission limits for distorting loads in MV & HV power systems”, and where<br />
appropriate Engineering Recommendations G5/4 is adopted.<br />
2.3.6.7.7 TNB uses the procedures contained in this document to plan the connection of loads producing harmonics and<br />

of Voltage Unbalance at the planning stage.<br />
) Under planned outage conditions, the maximum negative phase sequence component of the phase voltage<br />
on the distribution system should remain below 1% unless abnormal conditions prevail.<br />
) Under the planned outage conditions, infrequent short duration peaks with a maximum value of 2% are<br />
permitted for Voltage Unbalance, subject to the prior agreement of TNB under the connection agreement.<br />
TNB will only agree following a specific assessment of the impact of these levels on TNB and other<br />
Customers’ plant and equipment with which it is satisfied.<br />

NASIONAL B E R H A D
3) At the terminals of a Customer’s installation or specific Load the Voltage Unbalance voltage shall not<br />
exceed 1% for 5 occasions within any 30 minute time period.<br />
) In terms of traction Loads connected to the distribution system the acceptable limits of Voltage Unbalance<br />
are in accordance with “Engineering Recommendation (E/R) P29, issued by the Electricity Council of UK<br />
in 1984 entitled “AC Traction Supplies to British Rail” and its successor document P 29 issued in 1990<br />
“Planning Limits for Voltage Unbalance in the United Kingdom”. TNB uses the procedures contained in<br />
this document to plan the connection of Loads producing Voltage Unbalance and applies the limits therein<br />
in measuring and monitoring the levels of unbalance at such points of connection.<br />
2.3.7.2 In assessing level of Voltage Unbalance at the planning stage the assessment will be carried out at a realistic<br />

2.3.7.3 If under the operating conditions described earlier the Voltage Unbalance due to the Load exceeds the limits then<br />
balancing compensation equipment, which will reduce the unbalance to an acceptable level shall be installed<br />

reduction to be achieved shall be based upon enabling connection of other similar unbalance producing Load<br />
and/or permitting for future extension and development of the location with further unbalance producing Load<br />
installations. The balancing compensation equipment to be installed shall be of a type that does not cause<br />
resonance problems with the existing and intended future developments of the distribution system.<br />

types of equipment and protection settings, must be compatible with standard practices on the TNB’s system, and be as<br />
TNB specifies during the application for supply process. This is especially critical for MV and HV consumers.<br />

(b)<br />
(c)<br />
Maximum clearance times (from fault current inception to fault clearing) must be within the limits established<br />

Auto-reclosing or sequential switching features may be used on TNB’s distribution system. TNB will provide<br />
details on the operating sequence utilised for the supplies on the proposed installation so the consumer can plan<br />
for this in the design and protection of his facility.<br />
On some of TNB’s distribution systems, certain types of faults may cause disconnection of one phase only of a<br />
three-phase supply.<br />

SECTION 3.0: DEMAND ESTIMATION<br />
Supply schemes and networks are to be adequately designed or dimensioned to meet initial and growth of consumer<br />
individual and group maximum demand.<br />
The demand estimates are based upon load declared by consumer and TNB’s own information on load profile<br />
characteristics for various consumer classes. Range of values are given as demand profile are known to varies according<br />
to geographical location of consumers around the TNB service areas in Peninsular Malaysia.<br />
Fairly accurate assessment of individual and group demand of consumers are critical for correct dimensioning of network<br />

3.3 Demand Estimates For A Mixed Development Area.<br />
Accurate determination of the maximum possible demand for a newly proposed development is critical in the effective<br />
long-term planning of supply network within the specific area. Adequate land areas for transmission main intakes (PMU<br />
132/33kV, 132/22kV, 132/11kV), major distribution stations (PPU 33/11kV, 22/11kV), sub-stations (PE 11/. 415kV,<br />
22/. 415kV), underground cable and overhead line routes will have to be allocated at the layout approval stage by the<br />
relevant authorities.<br />
The total demand will indicate the supply voltage and target network configuration for the whole development area.<br />
Network facilities will be developed in phases in tandem with physical development.<br />
Site selections for PMU, PPU, sub-stations and feeder routes are normally made to achieve optimal technical performance<br />
of network and costs based on the planned target network.<br />
Appendix 15 indicates the sample M.D worksheet for a mix development area to be filled up and submitted to TNB at<br />
the supply application stage.<br />
3.4 Demand Projection And Substation Requirements For LV Scheme<br />
Demand projection of a new development area, say a proposed housing scheme, determines the number of sub-station<br />
requirements (11/. 415kV) in the design of low voltage system.<br />
Appendix 16 indicates the method for determining the overall numbers and capacity of sub-station for a typical housing<br />
or commercial scheme based upon the projected demand growth.<br />

SECTION 4: SUPPLY SCHEMES<br />
Based upon consumer declared demand level and required security level, supply schemes to consumers are appropriately<br />
designed to meet these requirements and planning criteria as discussed in section 2.<br />
4.1 Maximum Demand Levels And Supply Schemes<br />
The table below indicates the typical schemes for various demand levels of individual consumers. In the case of<br />
maximum demand (M.D) ranges of 5MVA to 10MVA, the supply voltage options of either 11kV or 33kV will ultimately<br />
be determined by the predominant supply voltage where the prospective consumer is to be connected.<br />
Consumers with M.D approaching 1000kVA have the option of taking supply at 11kV.<br />

4.2 Substation Categories, Type & Design<br />
4.2.1 Sub-station categories<br />
a. Transmission Main Intake (Pencawang Masuk Utama-PMU)<br />
Transmission Main Intake is the interconnection point of 132kV or 275kV to the distribution network. The standard<br />
transmission capacity and voltage transformation provided at the PMU are as follows:-<br />
44 TENAGA<br />
NASIONAL B E R H A D
- 132/33kV, 2 x 90 MVA<br />
- 132/22kV, 2 x 60 MVA<br />
- 132/11kV, 2 x 30 MVA<br />
b. Main Distribution Sub-station (Pencawang Pembahagian Utama- PPU)<br />
Main Distribution Sub-station is normally applicable to 33kV for interconnecting 33kV networks with 11kV networks.<br />
It provides capacity injection into 11kV network through a standardized transformation of 33/11kV.<br />
c. Main Switching Station (Stesyen Suis Utama- SSU)<br />
SSU at 33kV, 22kV and 11kV are established to serve the following function:-<br />
1. To supply a dedicated bulk consumer ( 33kV, 22kV, 11kV)<br />
2. To provide bulk capacity injection or transfer from a PMU/PPU to a load center for further localized distribution.<br />
d. Distribution Substation (Pencawang Elektrik – P/E)<br />
Distribution sub-stations are capacity injection points from 11kV, 22kV and sometimes 33kV systems to the low voltage<br />
network (415V, 240V). Typical capacity ratings are 1000kVA, 750kVA, 500kVA and 300kVA.<br />
Conventional substation designs are of indoor type (equipment housed in a permanent building) and out-door type<br />
(ground-mounted or pole-mounted). Standardized M & E design of 11/. 433kV sub-station is available at TNB offices.<br />
Compact substation (11/. 415kV) has limited application and is to be strictly applied in selective situations under the<br />
following circumstances:-<br />
• System reinforcement projects for highly built-up areas where substation land is difficult to acquire.<br />
• Any request to use compact substation for dedicated supply to a single or limited group of low voltage consumers is<br />
subject to TNB approval in accordance to site constraints situation, and to be considered as ‘special feature design<br />
schemes’.<br />
The main reasons for the above application criteria are as follows:-<br />
• Compact design reduces future system flexibility in terms of network expansion.<br />
• Compact design features, which limits the capacity of outgoing circuits.<br />

The establishment of transmission main intake also requires the allocation and acquisition of right of way or wayleaves<br />
for the transmission lines. Depending on the specific design of each PMU, the overall right of way or wayleaves<br />
requirements may be different.<br />
Developers of large-scale development areas, depending on the estimated demand may be required to allocate land for<br />
any or a combination of sub-stations categories, wayleaves or right of way for 132kV/275kV lines. These requirements<br />
will be specified by TNB upon submission of tentative layout plans and load estimates for the whole development<br />
area.<br />
4.2.3 Type of fire fighting System for the Substation<br />
Type of fire fighting system that is suitable for the substation has to meet the following criteria:<br />
• The fire extinguishing agent has to be the type that is approved by TNB.<br />
4.3 Standard And Special Feature Design Schemes<br />
Standard features of supply schemes are categorized as those typical design schemes for individual or consumer groups<br />
or classes. Typical cases are as follows:-<br />
(i)<br />
(ii)<br />
Supply scheme supplying domestic premises is predominantly through overhead systems and conventional substation.<br />
A fully underground network and any application of compact sub-station shall be considered as special<br />
features for which all extra costs incurred by TNB are to be paid in full by the consumer.<br />
Bulk consumers supplied at 11kV and above, are normally supplied via two in-feeds operating in parallel or nonparallel<br />
operation depending on the demand and security level required. If for any reason another dedicated cable<br />
is required purely for reasons of additional security, the extra costs shall have to be borne by the consumer.<br />
4.4 Supply Schemes For Interconnection To Embedded Generators<br />
Embedded generators depending on the capacity will be interconnected at 11kV and 33kV. The design of interconnection<br />
scheme or facilities, which may include protection, operational control facilities will be so determined to ensure safe,<br />
reliable and efficient interconnection scheme. The other design objective is to ensure that the interconnection of embedded<br />
generators should not negatively impact system performance and reliability to existing consumers connected to the TNB<br />
system.<br />
TENAGA<br />
NASIONAL B E R H A D<br />
