摘要
雷电侵入波过电压是对500 kV变电站电气设备绝缘构成威胁的主要方式之一。选取典型500 kV变电站,分析了杆塔与绝缘子的计算模型,并应用ATPD raw仿真软件计算500 kV变电站运行方式与工频电压相角对雷电侵入波过电压的影响。
Lightning incoming surge is one of the main causes that damage the insulation of the high voltage apparatus io 500kV substations. In this paper, a traditional 500kV substation is illustrated. The calculation models of tower and suspension insulator are analyzed. ATPDraw simulation software is used to calculate the effect of 500 kV substation operation mode and phase angle of applied voltage on the over-vohage caused by lightning incoming surge.
