远方备用电源自动投入装置

Remote BZT equipment

介绍了远方备用电源自动投入装置的技术特点。常用的备用电源自动投入装置 ,在两电源线路之间串接的 2个变电站开环运行时 ,只能满足在开环处变电站具有自动投入的功能 ,另一个变电站上级电源线路故障无法自投。本装置具有通信功能 ,可以与其他变电站的远方备用电源自动投入装置交换信息 ,更能够根据多个协调变电站之间联络线路及电源进出线路的电流、电压和开关位置等信息 ,实现多个变电站之间的备自投 ,大大地提高了供电可靠性。

The technical features of remote BZT equipment (automatic switchover of standby power source) are introduced.When two substations are operating in open loop mode with two power lines in serials, the normal BZT equipment can only realize the automatic switchover function of the substation at the open point.The remote BZT equipment has communication function and may exchange the data with the remote BZT equipment at other substation.Based on the information of several substations,such as the currents and voltages of power lines,switch states and so on,the coordinating BZT among several substations can be realized.It greatly increases the reliability and flexibility of power supply.
