220kv Transmission Line Fault Diagnosis and Analysis

摘要：

With the development of power system， reliability and stability of transmission lines requires a gradual increase，p articularly p ays great attention over voltage protection,but each year,the system still occur more accidents and Obstacles because of various over-voltage, the largest proportion of fault lightning trip，this paper analyzes the Hghfing trip accident with the 220kV ShaLi transmission llne, b ased on field data COIlection and analysis of this fault, explore and study the causes of lightulng over-voltage in power system and propose countermeasures to prevent similar accidents．
