摘要
本文研究了电力系统稳定器(PSS)和静态无功补偿器(SVC)的协调设计增强电力系统稳定性的问题。以基于非线性的目标函数最小值为优化目标,分析比较PSS和SVC协调设计与单独设计时,系统在三相短路时非线性时间响应。PSS与SVC均采用两个超前滞后控制设计。采用差分进化算法搜索最优控制器参数。非线性仿真结果分析表明,该方法在系统故障条件时的具有较高的有效性和鲁棒性。
In this paper, the stability of power system is enhanced by the coordination design of power system stabilizer（PSS） and static Var compensation（SVC）. Based on the minimum value of the objective function based on non-linearity, the nonlinear time response of the system in three-phase short-circuit is analyzed and compared with the coordinated design of PSS and SVC and the single design. Both PSS and SVC are designed with two advanced lag control. The optimal controller parameters are searched by differential evolution algorithm. The analysis of nonlinear simulation results show that the method is effective and robust in system failure conditions.
