摘要
500kV输变电工程的线路模型选择、实际工程中不同高抗补偿方式都对工频过电压有影响,笔者应用PSCAD电磁暂态仿真软件对在Bergeron、Mode Model、Phase Model线路模型下进行仿真分析,在正常计算方式下分析高抗补偿的最佳方式和补偿容量。通过实际工程说明在Bergeron线路模型下工频过电压最小,对于距离200~300 km在正常运行方式下采用受端补偿以及131%补偿容量时抑制工频过电压最为合适以及经济最为合理。以上分析对500kV实际工程启动有一定的指导意义。
Route selection model of 500kV power transmission project,the actual engineering in different high resistance compensation method has influence on power frequency voltage,PSCAD electromagnetic transient simulation software is used in Bergeron,Mode Model,Phase Model circuit simulation analysis model,the best way of high resistance compensation and compensation capacity in the normal way is analyzed.Through calculation the minimum voltage through the practical project of Bergeron in power line model,the distance of 200 km^300 km in normal operation mode used by the end of 131%when the compensation capacity and compensation to restrain the power frequency overvoltage is most appropriate and most economically reasonable.The above analysis has certain guiding significance to the actual 500kV project started.
