摘要
串补装置的正确运行对电网的安全稳定运行起着非常重要的作用,其中间隙自触发作为串补电容器和MOV(Metal Oxide Varistor)的过压保护,起着保护电容器和MOV的重要作用。本文在详细的介绍了间隙构成和间隙自触发的基本原理的基础上,以某电网串补间隙自触发故障为例,用EMTP仿真软件进行系统等值模型,模拟电网事故并进行计算。最后通过对比故障录波结论,验证事故仿真的正确性,并给出相应的处理措施。
Correct operation of series compensation plays an important role on the safe and stable operation of the grid. This paper introduces the formation of gap and the basic principles of gap self-trigger. The paper is based on the gap self-trigger event of a Power Grid, conducting system equivalent calculation with EMPT. Finally, this paper proposes the corresponding recommendations, and, through fault recorder conclusion, the inference to the calculation of the accident simulation will be verified.
