一种确定保护受串补电容影响区域的仿真方法
|
摘要
近年来国内外研究串补电容对线路保护的影响的很多,但是在研究电网中距离保护受串联补偿电容影响的区域的很少。在分析串联补偿电容对距离保护的影响的基础上,提出一种基于短路电流确定距离保护受串联补偿电容影响的电网区域的仿真方法。通过对比分析部分站点测量阻抗的理论分析结果和仿真计算结果应证了仿真方法的正确性。同时以一具体工程实例采用仿真方法计算出距离保护受串补电容影响的电网区域。
There are many papers researching on series capacitor's effect on distance protection in recent years, but few papers researching on the area in which the distance protection affected by the series compensation capacitor. This paper firstly analyzes the effect of series compensation capacitor to distance protection, secondly presents a simulation method of defining the area in which the distance protection affected by the series compensation capacitor based on the short circuit current protection. The validity of the simulation method is proved by comparatively analyzing the result of theoretical calculation and simulation calculation. At last, taking a specific engineering as an example, the paper defines the area in which the distance protection affected by the series compensation capacitor by using the simulation.
