Maintenance of Gas Networks<br />
Reliability of gas supply is the property of the gas supply system to deliver the<br />
required natural gas volume to the consumers uninterrupted, under the contract terms,<br />
in compliance with pre-set working parameters and within a certain time frame.<br />
The gas supply reliability rate is:<br />
determined in the concept project;<br />
underlying the working projects, the procurement of materials and<br />
equipment, the implementation and control of construction works and<br />
commissioning;<br />
maintained in the course of the system operation and restoration during<br />
implementation of restoration-repair works.<br />
Bulgartransgaz <strong>EAD</strong> and Overgas Inc. subsidiaries use SCADA system.<br />
SCADA serves to monitor the network pressure and flows, the natural gas<br />
composition and specific burning heat, the condition of the stop and control valves,<br />
the parameters of the devices. The data transfer is made through optic cable lines,<br />
telephone lines, satellite and radio connectivity. SCADA uses logic modeling<br />
programs, electronic equipment and standardization of computing networks.
