摘　　要：利用EMTDC模型研究了天广交直流并联输电系统及广西电网的过电压问题。模拟了各种不同的故障条件 ,如直流闭锁、整流侧交流系统故障、逆变侧交流系统故障及广西电网故障等 。With EMTDC model, this project studies the over-voltage problem in TSQ-GBJ HVDC/AC Parallel operating Transmission System and Guangxi grid. Different faulty conditions, such as the DC blacking, the faults existing in the AC system on the rectifier side, AC system on the inverter side and Guangxi grid, are simulated. Under these faulty conditions, the over-voltages appeared both in DC and AC systems are analyzed.
