摘要
将500kV变电站和进线段结合起来,在变压器安全的前提下选择不同的金属氧化物避雷器安装位置对电抗器进行保护。采用ATPDraw对雷电波及变电站进行仿真,并结合MATLAB对仿真结果进行计算。结果表明,在电抗器前和主变设置避雷器比在进线入口设置能更有效地防止雷电侵入波对电抗器及变电站内其他设备的危害。
Integrating 500 kV substation with inlet lines, protection for reactor was provided with selection of installation location of different type of MOA on premise of ensuring transformer safety. Simulation on substation and lightning surge wave was made with ATPDraw program, and its result was calculated with MATLAB program. The result shows that installation of MOA at power transformer and before reactor is more effective than at line inlet for preventing hazard to reactor and other equipments of substation due to lightning invasion.
