SVCs are widely used in power systems to maintain the voltage stability. Few attentions have paid on its characteristics under DC bias conditions. Based on a real steel company SVC system, simulations are done after theoretical analysis. It shows that the output reactive power cannot meet the voltage stability command; new control strategy should be made. The results of this paper provide reference...
F there does not have enough support as a means of reactive power sources, the modern power system voltage instability will occur. Beijing-Tianjin-Tangshan Power Grid is load center in North China, the region's power supply relies heavily on its long-distance and heavy-load interconnection of other power grids. At the same time the region does not have sufficient dynamic reactive power support, so...
