相间功率控制器运行特性仿真分析

以具体的相间功率控制器(interphase power controller——IPC)的基本结构为基础,采用MATLAB动态仿真工具SIMULINK,以两个电网间只由一条带IPC的联络线进行弱连接为例,仿真分析了IPC的运行特性。从仿真结果可以看出:(1)正常运行通过开关投切不同组数的电容器和电感器,可以有效地改变联络线传输的潮流。(2)在系统受扰动的情况下,当联络线受端侧发生短路故障,IPC具有电压解耦,使两侧电网相互隔离的优良特性;而当发生断线故障时,却容易引起送端侧IPC入口处电压下降和IPC电

Simulation analysis of characteristic for interphase power controller

Based on the practical structure of IPC, The model of two network connected by single tie-line with IPC is built by the SIMU- LINK--a dynamic simulation tool in the MATLAB,and the dynamic characteristics are studied.The simulation results show that (1) Under the normal operation condition, the load flow of tie-line can be changed efficiently by switching different capacitors and reactors. (2) When short-circuit fault occurs on receiving side of tie-line, IPC have the good attributes--decoupling voltage and interconnected networks; however, when there is an open-circuit fault, the voltage of the sending network is easy to recede and the capacitor may generate over-voltage.
