| 摘 要： | 随着电力系统的不断壮大,低频振荡问题日益突出,其中区域间低频振荡更为严重而且较难使用传统方法进行阻尼控制.采用静止无功补偿器SVC附加控制来实现区域间振荡的阻尼控制.通过时域仿真,比较了不同附加输入信号在区域联络线潮流变化情况下的阻尼特性.研究表明,线路电流幅值是其中最为合适的附加控制信号.

| Abstract: | With the development of power system in our country,electromenchanical oscillation has been concerned increasingly.Inter-area oscillation caused by generators in different areas can't be damped effectively with the traditional approaches.In this paper,an approach using additional damping control to static var compensator(SVC) controller is presented to damp inter-area oscillation.Then,the damping characteristics of different signals,when power flow on the tie-line changes,are compared by time-domain simulat... |
