摘要
针对电力系统动态模拟实验用的可控串联补偿 (TCSC)实验样机在实验过程中发现的电抗器支路电流波形与传统分析方法所得到的波形不一致的问题进行研究 ,发现波形的不一致是由于电抗器支路所具有的电阻所引起的。论文采用拓扑建模法 ,建立了包含电抗器支路电阻的TCSC数学模型 ,并推导出TCSC中电容支路两端的电压和电感支路中电流的时域计算公式。论文并结合数字仿真波形和动模样机实验结果 。
This paper finds out that it is the resistance contained in the reactance branch that makes the characteristic difference between the prototype TCSC used in the power system dynamic simulation laboratory and the traditional analysis results. Using a topological model building method,the TCSC steady state model with the resistance contained in the reactance branch is set up. The time domain representations of the voltage across the capacitor and the current in the inductance branch are deduced. With the help of digital simulation and the prototype test, the influence of the resistance contained in the reactance branch on the steady state characteristics of TCSC was investigated.
