摘　　要：为提高仿真效率及降低成本,将数字功率放大器应用于电力系统混合仿真。设计了基于FPGA的控制系统,将基于空间矢量的电流滞环控制方法应用于数字功率放大器,通过判断电流偏差变化率矢量的空间区域,选择合适的电压矢量,进而使电流误差控制在一定环宽以内。搭建实验平台,对各类指令电流进行跟踪实验,结果表明,研制的数字功率放大器控制精度高,响应速度快,能够满足电力系统仿真的实时性要求。In order to increase simulation efficiency and lower the cost,digital power amplifier was applied to power system hybrid simulation.Control system was designed based on FPGA,current hysteresis control based on SVPWM was applied to digital power amplifier,the best voltage vector switch was determined by the spatial distribution of current change rate,so that the current was controlled in hysteresis loop.Experimental platform was set up to test kinds of instruction current,Experiments show that the developed product has high control precision and fast response speed,can satisfy the real time requirement of power system simulation.
