| Abstract: | Introducing the principle of voltage control and slow susceptance control of static var compensator (SVC) composed of a thyristor controlled reactor (TCR) and fixed capacitors (FC), and combining its operation modes at Wuzhou substation, this paper analyzes the SVC action behaviour during power system faults and the corresponding coordination of the two control strategies. The results show that SVC can supply dynamic reactive power compensation to the power system depending on voltage level, and provide effective voltage support to the power system when faults occurred so to improve the system stability. |
