摘要：

In order to improve the performance of digital protective relay, a data acquisition and processing system based on FPGA is designed in VHDL and implemented in this paper. They are foul parts in system: ADC control, 32-point FFT module, frequency counter and power meter. It cans control ADC and multiplexer to sample and convert 16-channel voltage and current signal of power system, process the discrete data with FFT algorithms in real time, measure the system frequency and power. So it can supply the processed data for protective relays and measurement All parts can be implemented in an Altera ACEX EP1k100. Using this system, the protective relays will achieve the good characteristic: high reliability and performance, multi-function, small size and cheap cost.
