摘要
在一些具备双电源线路的变电站,利用线路备自投装置是提高供电可靠性的有效办法。但是在实际运行中可能会遇到如电网不稳定运行、线路过载、电压回路断线等问题,这些都是影响线路备自投装置正确动作的重要因素。结合实际情况,采取了一些改进措施,在电网运行中取得了较好的效果。
Using reserved auto-switch-on device in substations with double terminal source trasmission line is an effective way to improve reliability of power supply.However,in practical operation some problems would influence the correct operation of reserved auto-switch-on device such as power gird unstable operation, line overload, voltage loop breaking. According to practical situation ,the improvement measure was adopted in Ji＇an power grid and reserved auto-switch-on device received satisfactory result.
