摘要
电力系统作为一个庞大的输电系统,由于覆盖面广、运行环境恶劣,经常出现特殊的运行条件,也必然会对保护装置及用户产生影响。在结合微机差动保护装置算法及仿真建模的基础上,分析了负相序对差动保护的影响,并给出了相应的处理方法。
As a huge transmission network, power system is always running at special conditions which have a great affection on protection. Based on the arithmetic of differential protection and simulation technique,this paper analyses the influence of the negative sequence to power system. Finally, the measure of the problem is proposed.
