电源故障

The scheme of double power sources with each line sectionalized into 3 sections and equipped 5 reclosers has been proved higher reliability. However,the coordination of protection among equipment is quite difficult,and problem of multiple short-circuit surge to faulty apot has not yet been solved for this scheme.

双电源环网每条线路分3段的5组重合器供电方案，供电可靠性会更高，但该方案设备间的保护配合十分困难，向故障点多次短路冲击问题，一直未能很好地解决。

Voltage sags may be caused by faults on the transmission or distribution system, or by the switching of loads with large amounts of initial tarting\inrush currents (motors, transformers, large DC power supplies).

电压下跌可由输配电系统中的故障引起，或由投切具有大初始起动电流；涌流(电动机，变压器，大型直流电源)的负荷引起。
