摘要

combined with the dynamic characteristics of single shaft structure of microturbine, The model of mi⁃croturbine is established based on PSCAD/EMTDC in this paper. The thetopological structure of power electron⁃ic device and the PQ control strategy of inverter are given. Simulation results show that microturbine generation system consistent with the actual, and single shaft microturbine has better dynamic characteristics. The power electronic devices can provide power on grid, and the active power and reactive power are independently control⁃lable.%结合单轴结构微型燃气轮机的动态特性建立PSCAD/EMTDC模型，同时给出了电力电子装置的拓扑结构及逆变器的PQ控制策略。仿真结果表明，整个微型燃气轮机发电系统与实际相符，单轴结构微型燃气轮机具有较好的动态特性，辅以电力电子装置后能够实现电能的并网输出，且有功功率与无功功率独立可控。
