STATCOM对多机电力系统暂态稳定性能影响的仿真研究

Research on Simulation of STATCOM in Multi-source Power System Transient Stability

针对一个两区域且区间联络线中间带STATCOM的四机电力系统,首先建立了其数学模型并设计了STATCOM多目标模糊控制器;然后应用MATLAB仿真软件,对不包含和包含STATCOM的四机电力系统分别进行了仿真分析和比较。仿真结果表明,STATCOM在改善多机电力系统暂态稳定性能方面的作用是十分明显的。

For a two-area four-source power system with STATCOM connected at the electrical mid-point of the inter-area transmission line,the mathematical model is firstly established.At the same time,a new type of multi-objective fuzzy controller is designed for STATCOM.And then using MATLAB,the detailed simulation and comparison on the four-source power system with and without STATCOM is presented and compared.The simulation results show that STATCOM can greatly improve the transient stability of multi-source power system.
