同塔多回输电线路雷击同跳分析及应对措施研究
|
摘要
统计分析了近年广西电网同塔多回架设输电线路雷击同跳情况,选取了某220kV同塔双回输电线路典型雷击同时跳闸故障进行复原仿真分析,得出陡波头雷电流是造成双回线路多相闪络的主要原因。同时,针对该同塔双回输电线路雷击跳闸,结合线路走廊落雷和线路杆塔结构等参数,以此为基础开展该线路的雷害风险评估分析,最后根据评估结果,采用加装线路型避雷器等措施有针对选取高风险杆塔进行改造。
Statistical analysis on lightning strike simultaneous trip-out of multi-circuit transmission line of Guangxi power grid in recent years are carried out,and The simulation analysis of the typical lightning strike and tripping fault of a 220kV double-circuit transmission line on the same tower is carried out. It is concluded that The steep wave head lightning current is the main cause of multi-phase flashover in double-circuit lines. At the same time,aiming at the lightning tripping of the double-circuit transmission line on the same tower,combining the parameters of the corridor lightning and the tower structure,the risk assessment of the lightning hazard on the line is carried out. Finally,according to the evaluation results,measures such as the installation of line-type arresters have been adopted to select high-risk towers for transformation.
