Substation secondary cable has extremely important problem of electromagnetic compatibility

With increasing voltage levels and secondary equipment more and more decentralized, substation secondary circuit already in a strong electromagnetic environment in recent years has multiple causes substation DC system disruption caused by the secondary  electri cenergy meter  no fault tripping accidents, which caused a serious threat to the grid, affecting the safe and reliable operation of power systems. Therefore, the study of secondary cable substation electromagnetic compatibility  Voltage stabilizer  a very important theoretical significance and practical value. This paper focuses on the finite difference time domain method based on  air circuit breaker  transmission line theory and electromagnetic interference on the secondary substation cable coupling situation.
