摘要
随着电网网架扩张、电力用户大规模接入,因输变电设备及用电设备故障导致的电压暂降愈发频繁。通过对电压暂降进行仿真分析,研究电压暂降发生后的用户敏感设备供电母线残余电压,评估敏感负荷的电压暂降抗扰度。针对电压暂降抗扰度不足情况,合理选择电压暂降控制措施不仅能妥善解决电压暂降导致的敏感负荷脱网问题,对改善供电用电双方关系也有着重大意义。
With the expansion of the power grid and the large-scale access of power users,voltage transients caused by faults in transmission and transformation equipment and electrical equipment have become increasingly frequent.By simulating and analyzing voltage sag,the residual voltage of the power supply bus of sensitive equipment after voltage sag occurs is studied,and the voltage sag immunity of sensitive loads is evaluated.Reasonable selection of voltage sag control measures for insufficient voltage sag immunity can not only effectively solve the problem of sensitive load disconnection caused by voltage sag,but also have significant implications for improving the relationship between power supply and consumption.
