摘　　要：为了使配电网在线故障定位实用化,文章特设计了基于GPRS与Delphi的单相接地故障指示器的中心站。故障指示器安装在10 kV高压输电线路上,实时采集高压侧的相位和电流信息,然后将采集到的数据经A/D变换,通过GPRS无线网络传送到变电站的PC机,PC机把Socket接收到的数据通过Delphi的DBCOM控件传送到组态软件的数据库,使数据动态的显示在界面上。当线路发生单相接地故障时,组态软件给出报警信息,方便工作人员查询。In order to make online fault location in distribution network practical, this article designs a ground fault indicator central station based on GPRS and Delphi. Fault indicator is installed on the 10kv high-voltage transmission lines. The highvoltage side of the phase and current information are collected in real-time manner. After A/D converter, the collected data is transmitted to the PC in substation through GPRS wireless network. The data received by Socket is then transmitted by PC through the Delphi DBCOM control to the configuration software database, displayed dynamically on the display. When a ground fault occurs, the configuration software will give the alarm information to the facility staff for enquiring.
