基于FPGA的农村电网的故障录波器的系统设计

Esign of Rural Power Network Fault Recorder System Based on FPGA

随着农村电网的改造和发展,农村用电对电力系统的安全性要求越来越高,为了适应市场需求,针对传统的故障录波器的采样率低,成本及故障再现不准确的现象,设计一种基于FPGA+DSP的故障录波系统,采用EP1C3T144作为控制器,设计了具有电网信号的采集、记录、存储、分析和完成各电能质量指标检测的功能的录波检测系统,同时,并详细地介绍了装置的软硬件结构和功能。试践证明,该系统具有实时采样、同步误差小、电能参数检测等特点。

Along with the development of rural power,rural power system security is increasing,in order to meet market demand,Against the phenomenon of traditional faulty recorder low sampling rate,cost and Failure inaccurate representation.The paper designed the faulty recorder system based on FPGA＋DSP,EP1C3T144 used as a controller,designed a recorded wave systems which could achieve power signal collection,recording,storage,analysis,completed testing of the power quality. Description of the device structure and function of the hardware and software,which possess exact sampling,synchronous error detection features.
