在研究含有风电的电力系统时,简化的风电场模型有利于系统的仿真分析。为提高风电场等效模型的精度,提出一种基于非电气参数的风电场等效建模方法。从风电机组的控制参数、输入风速和风力机参数3个部分进行聚合、等效,得到对应的风电场单机等效模型。在MATLAB/Simulink软件中建立风电场模型和等效模型进行仿真研究。通过对比分析验证了这种等效建模方法的有效性和准确性。
While researching on the power system with wind power, simplified model of wind farm is conducive to the simulation of this system. In order to improve the accuracy of equivalent model for wind farm, an equivalent modeling method, which is non-electric parameters based, is present- ed. The equivalent maximum power curve, equivalent wind speed of wind farm and equivalent pa- rameters of wind turbine is calculated. Then a single equivalent model is presented. A simulation is developed by using Simulink of MATLAB. The comparison and analysis verify that the methods are effective and accurate.
