摘　　要：静止同步串联补偿器(SSSC)是可实现阻尼系统功率振荡的重要交流输电装置。在研究了SSSC的基本拓扑结构和数学模型的基础上,分析了SSSC工作时产生具有可控幅值、相角的同步电压差与系统进行功率交换来实现补偿的动态调节过程。设计了一种含有灰狼优化(GWO)算法的功率振荡阻尼控制器,通过GWO算法实现了控制器主要参数的优化。搭建了接入额定容量100 MVA SSSC的电力系统仿真模型,模拟了分布式发电并网输出功率不稳定引发电网功率波动及三相接地短路故障等暂态工况,验证了本文引入的SSSC能起到良好的阻尼作用,提高电力系统的稳定性。Static synchronous series compensator(SSSC)is an important AC power transmission device that can damp power oscillation of the system.In this paper,the dynamic adjustment process of SSSC working with synchronous voltage difference with controllable amplitude and phase angle with system power exchange to realize compensation is analyzed on the basis of studying the basic topological structure and mathematical model of SSSC.A power oscillation damping controller with grey wolf optimization(GWO)algorithm is designed.The main parameters of the controller are optimized by GWO algorithm.The power system simulation model with the rated capacity of 100 MVA SSSC is built to simulate the transient conditions such as grid power fluctuation and three-phase grounding short-circuit fault caused by the unstable output power of the distributed generation,which verifies that the SSSC introduced in this paper can play a role.Good damping effect to improve the stability of the power system.
