针对RTDS仿真系统暂态数据大容量高速度的传输要求,开发了一种基于现场可编程门阵列(field programmable gate array,FPGA)技术的高速通信方法。基于该方法,研发了特性展示主站与RTDS的数据通信系统,能够进行微秒级别的高精度高速采样,可将RTDS仿真的微秒级暂态数据实时传输并存储到主站,支持主站的实时推送功能或回放分析功能。基于吉比特收发器FPGA(Gigabit Transceiver FPGA,GTFPGA)卡内置的高速通信Aurora协议开发了RTDS仿真器、GTFPGA卡和电网特性展示系统间的通信模块,通过网络Win Pcap软件实现RTDS实时数据的传输,实现暂态数据的展示和回放分析。该模块以光纤为传输介质,以高性能FPGA为数据采集系统,具有良好的通用性和可推广性。
In order to meet the requirement of large capacity and high speed transmission of transient data in RTDS simulation system, a high speed communication method based on field programmable gate array (FPGA) technology has been developed. Based on this method, a data communication system with characteristic display master and RTDS has been developed, which can perform high-precision and high-speed sampling at the microsecond level. The microsecond-level transient data of RTDS simulation can be transmitted and stored to the master station in real time, Real-time push function or playback analysis function. Based on the high speed communication Aurora protocol built in the Gigabit Transceiver FPGA (GTFPGA) card, a communication module between RTDS emulator, GTFPGA card and power grid display system was developed. Real-time RTDS data transmission was realized through Win Pcap software. Transient data display and playback analysis. This module takes the optic fiber as the transmission medium, takes the high-performance FPGA as the data acquisition system, has the good versatility and the promotion.
