摘　　要：为了精确地计算500kV输变电工程内过电压,文中创新性地对线路采用小开关技术,使BPA与PSCAD在500kV变电站网络等值中无缝对接,实现PSCAD模型运行电压、潮流与BPA所显示潮流一致。同时利用机电暂态软件BPA对500kV汗白Ⅱ线工程进行工频过电压计算,与电磁暂态软件PSCAD计算结果对比非常接近,结果表明,BPA软件也可以有效计算工频过电压。In order to accurately calculate the overvohage in 500 kV power transmission and trans- formation project, the innovative line with small switch technology make BPA and PSCAD seamless con- nected to the 500 kV substation network equivalent, realize the operating voltage, tidal current of PSCAD model is same as the BPA shows. At the same frequency overvoltage calculation is carried out on 500 kV Hanbai Ⅱ line project by using electromechanical transient software BPA, compared with the re- sults of the electromagnetic transient software PSCAD, the comparison is very close. The results show that the overvoltage can also be calculated by BPA software.
