Switching device switching time optimal configuration method suitable for incoming line of distribution network substation

The invention discloses a switching device switching time optimal configuration method suitable for incoming lines of a distribution network substation, and the method can effectively improve the safety of power supply of a distribution network and the reliability of power supply of the distribution network, and avoids equipment damage and power grid accidents. According to the method, whether the power flow after loop closing and battery changing is overloaded and whether the bus voltages on the two sides are out of limit are checked in advance mainly through power flow calculation, the battery changing time parameters after loop closing are optimized, and it is ensured that the transient process is finished and enters a stable state. Therefore, the method is suitable for popularization. 本发明公开了一种适用于配网变电站进线的换电装置切换时间优化配置方法，该方法能有效提高配网电力供应的安全性和配电网供电的可靠性，避免设备损坏和电网事故的发生。该方法主要通过潮流计算提前校核合环换电后的潮流是否过载，两侧母线电压是否是否越限，并优化合环后的换电时间参数，确保暂态过程已经结束，进入了稳定状态。因此，适宜推广应用。
