摘要
为验证宁夏电网±660 kV直流输电系统双极闭锁后安稳装置控制策略的正确性及安稳装置切机后对系统稳定性的影响,采用电力系统全数字实时仿真系统(Advanced DigitalPower System Simulator,ADPSS)进行故障仿真,仿真过程中,安稳装置动作可靠,系统保持稳定运行。仿真结果表明:安稳装置动作后,直流系统附近各线路电压在短暂波动后均恢复平稳,线路无过载现象。
In＇order to verify the correctness of control strategy of the safe and stable installation after double-pole closedown of ±660 kV direct current transmission system in Ningxia Power Grid and the influence of the safe and stable installation switched off on the stability of electric power system, adopts the Advanced Digital Power System Simulator （ADPSS） to make the failure simulation analysis, The simulation result shows that the voltage of transmission lines in the neighborhood of direct current system resume stability after occured short-term fluctuation, the transmission lines are no occur over loading.
