基于FPGA的电力传动实时仿真平台的设计

Design of Power Drive Real-Time Simulation Platform Based on FPGA

针对传统电力传动仿真软件如MATLAB/SIMULINK具有仿真时间长、对计算机硬件要求高等缺点,给出了一种针对电力电子装置实时仿真系统的建立方法,通过对带阻感负载的H桥逆变器进行特性模拟,给出了基于System Generator的实现流程。在FPGA内部实现一个SPWM信号发生器、H桥仿真器及阻感负载仿真器,构成一个完整的单相H桥逆变系统。最后在Xilinx公司S3EStarter_ug230 FPGA实验平台上对整个系统进行实时仿真,并采用DAC对仿真波形进行输出显示,结果验证了整个实时仿真系统的正确性。

Traditional simulation software such as MATLAB/SIMULINK has shortcomings of low speed and high demand for computer hardware. This paper presents an FPGA based real-time simulation for power electronic devices. An SPWM signal generator, an H-Bridge inverter simulator and a RL load simulator are realized on one FPGA chip, thus creating an H-Bridge inverter system. A DAC is used to show the simulation waveforms. The proposed simulation system is realized using a S3EStarter_ug230 platform from Xilinx, Inc. Experimental results are then presented for verification.
