Appendix 1OO 6T-29Effective Date: 02 July 2014Page 6 of 13EMLS – Lower Mainland Area1.0 EMERGENCY MANUAL SHEDDING BLOCKSManual load shedding may require up to 50% of the area load to be shed in 3 blocks within 5 minutes.The shedding described in the table in Section 2 is in order of priority within each block.If under frequency load shedding has occurred, some of the loads may already have been shed. Boldand underlined stations and/or their loads are part of the automatic under-frequency load sheddingscheme and might have been tripped should this auto shedding scheme have operated. MW (auto) inthe table summarizes the amount of load shed by automatic under frequency load shedding.Voltage should be monitored frequently while load is being shed. At the direction of the TC, circuitsshould be cut out as necessary to control the voltage.Once load shedding complete, switching should commence to restore station service to affectedstations.2.0 EMERGENCY MANUAL LOAD SHEDDING PROCEDUREShedding should be carried out using the EMLS_OV screen as shown in Appendix 5 (Figure 1). Thereal time loading on each element to be shed is shown on the screen.
