摘　　要：将500kV变电站和进线段结合起来考虑,通过选择氧化锌避雷器的位置,在变压器安全的前提下设置不同的方案来对电抗器进行保护,采用ATPDraw进行仿真,并结合MATLAB对仿真结果进行计算。证明在电抗器前架设避雷器比在进线入口架设更能有效的防止雷电侵入波对电抗器及变电站内其他设备的危害。Considering a combining of a 500kV Substation with the Inlet lines, On the premise of ensuring the trans- former＇ s safety to choose the location of the MOA, putting forward different kinds of project to protect the reactor, Simu- lation analysis is presented over the ATPDraw and calculated the Simulation result on MATLAB. Proved that the location of the MOA to be setup in front of the reactor more effective than in Inlet lines erecting to prevent lightning invasion wave reactor and other equipment inside the substation harm..
