对采用不同控制策略的风电场接人系统进行了稳态分析,通过绘制不同控制策略下风电场公共接入点(PCC点)、地区电网电压中枢点和重要变电站的P-U曲线,分析了风电接人后地区电网的电压、网损变化;对采用不同控制策略的风电场最大接人容量进行了研究;最后,在不同的稳态约束下,讨论了风电接人系统的最优控制策略的选择问题。
The paper discusses the static analysis on the regional power grid including wind farms that adopt different control strategies, and analyzes the voltage,the grid toss and the maximum power injection of wind farm by picturing the PV curves and grid loss change curves, finally, discusses the optimal control strategy of wind farm based on static constrain.
