摘　　要：研究了含双馈电机的风电场接入配电网后的无功电压优化控制方法,通过分析双馈感应风电机组的功率情况,充分发挥双馈感应风电机组对配电网的无功调节能力,将构建的无功优化问题转换为一个非线性混合整数优化的数学问题,并采用智能遗传优化算法进行求解。利用IEEE30节点系统作为算例进行仿真分析,计算结果可为含风电场的配电网提供合适的无功分布参考,验证了该控制方法的有效性。Study was made on the reactive voltage optimization control method after wind farm with doubly-fed induction generator connected to distribution network. Via analysis to power conditions of doubly-fed induction generator set, the reactive power regula- tion capacity of doubly-fed induction generator set was given full play for distribution network. The problem to construct reactive power optimization was converted to a non-linear mixed integer optimization problem which was solved by intelligent genetic algo- rithm. The IEEE 30-node system was chosen as an example for simulation. Calculation results can provide references of suitable reac- tive power distribution for distribution network containing wind farm. It verifies the validity of the control method.
