通过对影响无功补偿性能的不同情况进行仿真，比较了常规同步电容器、超导同步电容器和静止无功补偿器(SVC)在电网中的动态性能。结果表明，SVC注入更多的无功功率，在终端电压降较小的故障时，如弱电网中的单相接地故障，具有更好的动态性能。另一方面，同步电容器使电压恢复到额定值的速度更快，对刚性电网中的三相接地故障等严重故障表现出更好的动态性能。在附近的三相接地故障期间，超导同步电容器注入的无功功率比传统的同步电容器多45%。
In this paper, a comparison of the dynamic performance between a conventional synchronous condenser, a superconducting synchronous condenser, and a static Var compensator (SVC) is made in a grid setup by simulating different cases that affect the performance of reactive power compensation. The results show that the SVC injects more reactive power and has a better dynamic performance during faults that cause a moderate or minor voltage drop on its terminals, such as single-phase to ground faults in weak grids. The synchronous condensers, on the other hand, bring the voltage to the nominal value quicker and show a better dynamic performance for severe faults such as three phase to ground faults in stiff grids. The superconducting synchronous condenser injects up to 45% more reactive power compared to the conventional synchronous condenser during a nearby three phase to ground fault.
