摘　　要：随着电力电子技术、微处理技术和控制技术的发展,柔性交流输电系统FACTS(Flexible AC Transmission System)的出现,为电力系统急待解决问题提供了新的手段或策略。静止无功补偿器(SVC)作为FACTS家族的成员之一,对电力系统性能的改善也已取得了可喜的成绩。因此,从静止无功补偿器提高稳态输送容量、提高暂态稳定性、增强系统阻尼抑制低频振荡、缓解次同步谐振、预防电压不稳定或控制电压的波动、改善直流输电系统的性能等六个方面进行综述。With the development of electric power technology, computer technology and control technology, the Flexible AC Transmission System （FACTS） appears which supply some new means to raise transmission capacity and improve power system stability. The static Vat compensator （SVC） which is one of FACTS is an effective device to improve system performance, which has been proved. In recent years, the static Var compensator （SVC） is used extensively. Therefore, the effect of static Var compensator on power system is analyzed deeply. Some functions are elaborated in detail, such as raising transmission capacity, improving power system stability, strengthening system damping, relieving system sub-synchronous oscillation, preventing the voltage fluctuation, and optimizing HVDC transmission system performance.
