通信串口在远方备自投上的应用

Application of serial interface in distance standby power automatic devotion

提出了一种利用电力通信系统现有串口技术设备 ,实现电网内多个变电站之间电源互为备用的远方备自投的技术方案。该方案将通信串口技术、数字传输技术、信号转换技术及备自投技术应用于远方变电站 ,实现远方备自投功能 ,满足快速、可靠的高质量供电要求 ,同时也拓展了电力系统通信的业务应用范围。

In this text it has brought forward a sort of technology scheme,which use the existing serial interface devices in electric power communication system to realize the distance standby power automatic devotion which power supply are spare each other between several transformer substation in power system.It applies to distance transformer substations with communication serial interface technology,data transmission technology,signal conversion technology and standby power automatic devotion technology in such scheme,and so as to realize distance standby power automatic devotion function,satisfies the fast,reliable and high quality power supply request,at the same time it will also develop the operation application range for electric power communication.
