风电穿透功率极限的计算与分析

Calculation and analysis on the Wind power penetration limit

建立了异步发电机的稳态数学模型,表明风电穿透功率极限是系统的网络结构、风电并网节点位置、负荷水平、机组的最小出力限制、系统对电压水平的要求、风电场无功补偿容量等因素综合作用的结果,制约系统风电穿透功率水平的主要原因是风电功率注入引起的节点电压越限。

This paper establish a steady-state asynchronous generators mathematical model, showed that wind power is the ultimate power through the network structure, wind power and network node location, load level, the smallest unit of output restrictions, the voltage level of system requirements , Wind farm capacity of reactive power compensation factors such as power penetration level of wind power is the main cause of the result of restricting power system wind the node into the voltage limit.
