A Real-time Hardware-in-the-loop Simulator of APF

在大功率电力电子装置的设计与测试中,实时仿真发挥着越来越重要的作用。文中基于时间平均法建立了有源电力滤波器(APF)的实时数字模型,采用数字信号处理器(DSP)和现场可编程门阵列(FPGA),实现了一种通用的低成本的硬件方针手段,通过并行计算技术,建立电力电子器件的电磁暂态模型与散热模型,确保仿真速度的同时提高了仿真细度,能够真实地模拟电力电子器件的电磁暂态和热动态过程,测试控制器各方面的性能。

Real-time simulation is playing an increasingly important role in the designing and testing of high capacity electric equipment. In this paper, a method of hardware simulation based on DSP and FPGAs is presented. The real-time model of APF is implemented based on the time average method. By means of parallel computing, this paper provides a cost-effective and generally-applicable solving method. With transient models of electric devices, the simulator provides authentic simulation of transients and the heat dynamic process to test the functions of the controller.
