摘要
灵活交流输电系统(FACTS)可实现对电力系统的某个或多个参数进行控制,以提高系统的稳定性和传输容量。介绍了主要几种FACTS控制器的组成及其对电网的作用,给出了FACTS技术在电力系统稳态和动态中的具体应用,即可进行快速、连续、灵活的无功功率、电压和动态潮流控制,抑制系统低频振荡和次同步振荡,提高电网的动态性能和稳定水平。
A flexible AC transmission system （FACTS） can realize control for certain parameter or multiple parameters of power system, so as to raise stability and transmission capacity of the system. Introduction was made to the construction of several concrete FACTS controllers and its effect to the power gird. Actual application of FACTS technology was given in stable and dynamic status of power system. Reactive power, voltage and dynamic flow control could be carried out fast, continuously and flexibly, which restricted the system’s low frequency oscillation and subsynchronous oscillation, to raise dynamic performance and stability level of power grid.
