摘　　要：介绍云南省风电场多位于山区,风机分布不规则,沿山势走向呈长条状分布,集电线路长且各台风机出力不均匀,容易导致风电场内部出现电压越限的情况。根据云南山地风电场的特征建立了典型模型,研究山地风电场内部电压不均衡情况,并且验证了在大规模电力系统仿真计算中采用的风电场一般等值模型的适用性。Wind farm in Yunnan province is located in the mountains,the wind machine irregular distribution,to form a long strip shape distribution along the mountains. Wind farm collecting circuit is long and every wind generator output is not uniform,easy to cause the wind farm voltage exceed the limit. This paper established the typical model according to the characteristics of Yunnan mountain wind farm,studied the mountain wind farm voltage imbalance,and validated the applicability of wind farm equivalent model used in the ordinary in large-scale power system simulation.
