摘　　要：基于风电出力和出现频率的区间划分,研究了集群风电出力特性的分析方法,提出了集群风电的瞬时最大出力系数、最低保证出力系数和有效容量系数3个重要出力特性指标。以甘肃酒泉千万千瓦级风电基地为例分析了集群风电出力特性,得到了具有重要参考价值的评价指标。同时,分析了大容量风电参与电力系统电力平衡时,最大瞬时出力系数、最低保证出力系数和有效容量系数的3个出力特性指标的应用场合和应用价值。Based on the statistical method of time probability about wind power output levels, three important indicators for out- put characteristics of clusters of wind power are proposed, that is, the instantaneous maximum output coefficient, the minimum guaranteed output coefficient and the effective capacity factor. Taking Jiuquan million kilowatts of wind power base in Gansu Province for example, the output characteristics of clusters of wind power are studied, and some evaluation indicators with im- portant reference value are obtained. At the same time, the application condition and application value of these three indicators are analyzed when large capacity wind farms participate in power balance of power system.
