摘　　要：基于当前微电网研究领域热点,在某些不考虑具体设备暂态过程的仿真研究中,为缩短建模时间和仿真时间,滤除仿真结果中的谐波干扰,针对分布式电源详细模型的本质特点,对其组成部分原动机和逆变器分别进行简化,提出相应的简化模型。在光伏并网的仿真场景下,建立整体仿真模型,将详细模型与简化模型进行对比可知:简化模型不仅在稳态时达到了与详细模型相同的结果,而且暂态响应优于详细模型,达到了预期的对简化模型的要求。As microgrid becomes the current research hotpot in the filed of electricity, the specific device＇ s transient process is not be considered in some simulation studies. In accordance with a detailed model＇ s essential characteristics of a distributed power, this paper simplifiesits components, namely prime mover and inverter, separately and proposes the corresponded simplified models, in order to shorten modeling time and simulation time and eliminate harmonic interference in simulation results. In the simulation background of photovoltalc grid-connected, through the establishment of an overall model of photovoltaic grkd- connected, this paper makes a comparison between the detailed model and the simplified model, confirming that the simplified model not only gets the same results in the steady state with the detailed model, but also represents a better transient performance than the detailed model, which achieves the desired requirements for the simplified model.
