摘　　要：在系统阐述微型电网提出的背景和存在意义的基础上,分析了系统在并网和孤岛时的稳定性特点,详细介绍了P/Q控制方法的原理。在基于MATLAB/Simulink的环境下,建立了具有多个微型风电电源的微电网模型,并进行仿真分析。通过对该微型风电网运行模式切换的仿真分析,验证了控制策略的有效性和正确性。On the basis of the systematical demonstration of the background and significance of micro wind power grid, this paper analyzes tile stability characteristics of the system connected and isolated to grid, and introduces the principle of P/Q control. The establishment of wind power system model, and then in the MATLAB/Simulink based environment, the system to establish the micro - grid model with a number of micro - wind power supply, and simulation analysis. Through the simulation analysis of operation mode switch of micro wind power grid, the ef- fectiveness and correctness of the control strategy is verified.
