针对传统电力电子仿真系统仿真算法步长太长.仿真速度不够快的问题,提出了一种基于现场可编程门阵列(Field Programmable Gate Array,FPGA)模块化并行计算的半实物仿真系统,可用于电力电子的控制器测试中。首先阐述了如何在FPGA中实现电力电子元器件模块建模,并提出各模块交互连接的并行计算策略。通过FPGA仿真软件Modelsim仿真与半实物仿真系统实验结果得出:该半实物仿真系统的单步仿真步长为0.1μs,可用于控制器实时控制中。通过对搭建在仿真系统上的并联逆变器进行起动控制实验,结果表明该仿真系统仿真速度快、准确度高且成本低,易于普及推广使用。
Aiming at the problem that the traditional algorithm of the power electronic simulation system is too long and the simulation speed is not fast enough, a semi-physical simulation system based on modular parallel computing of Field Programmable Gate Array (FPGA) Power electronics controller test. First of all, it shows how to implement the module of power electronic components in FPGA and put forward the parallel computing strategy of each module interconnection. The simulation results of Modelsim simulation and semi-physical simulation system based on FPGA simulation software show that the single-step simulation step size of the semi-physical simulation system is 0.1μs and can be used in the real-time control of the controller. The start-up control experiment of the parallel inverter built on the simulation system shows that the simulation system has the advantages of fast simulation speed, high accuracy and low cost, and is easy to popularize and popularize.
