摘　　要：基于FPGA+DSP架构开发了用于GIS局部放电在线监测的数据采集系统。该系统采用声电联合法检测放电信号,通过FPGA控制采样,由DSP对数据进行处理和发送。在试验GIS装置中人工模拟绝缘缺陷,对系统进行测试,通过监测信号计算出的放电源位置与实际情况符合。该系统能够实现对GIS局部放电信息的实时采集和传送。In recent years, in order to ensure the safe operation of power system, the partial discharge on-line monitoring in GIS is becoming more and more important. So a multi-channel, high sampling rate data acquisition system is been needed to achieve real-time acquisition and transmission of discharge information. Developed data acquisition system, which used in GIS partial discharge on-line monitoring, based on the FPGA ＋ DSP architecture. The system detects the signal of discharge by UHF and UE combined. While FPGA control sampling, data processed and sent by DSP. Simulating insulation defects in experimental setup of GIS to testing the system. The discharge position calculated by the signal conform to the actual situation. The system can achieve real-time acquisition and transmission of GIS partial discharge information.
