WebWhether the load should be shed in a single stage or in multiple stages and the under voltage relay time delay settings can be accurately determined only through dynamic analysis. Figure 4-6 below has been taken from reference [5] and shows the results of major disturbances and how load shedding applied in a timely manner can prevent voltage ... WebApr 12, 2024 · Load shedding (LS) is one of the ways to deal with FIDVR and STVI and reduce the imbalance between the generation and demand of reactive power. Under-voltage (UV) relays that disconnect loads during voltage drop cannot effectively deal with this phenomenon because of their inability to detect the effective loads on the reduction of … peavey pm16s
