风电场发电机数量众多，在研究含有大规模风电机组的电力系统稳定性时，为减少仿真计算量和时间．可采取动态等值的方法对风电场进行简化，为此提出了基于改进加权法的恒速风力发电机参数聚合实用化方法。在MATLAB／SIMUUNK工具箱中对一实例系统进行建模和仿真，结果表明了该等值方法的正确性、精确性、简便性和有效性，为大规模并网型风电场的进一步研究提供了有利条件。
英文摘要：
While researching on the power system stability of large-scale wind power unit, it takes a long time because the wind farm consists a lot of generators. To reduce the simulation time,some dynamic equivalent ways for simplifying the wind farm are necessary. In this paper, an improved practical approach is proposed, which is based on the weighted arithmetic to make the wind turbine parameters polymerized. In MATLAB/SIMULINK toolbox, a case of a system is modeled and simu- lated, and the results show that the equivalent approach is of accuracy, precision, simplicity and effectiveness. Therefore this equivalent approach will make the further research on the power sys- tem stability of large-scale wind power unit more convenient and flexible.
