摘要 研究了就风电接入电网的潮流计算问题,提出相应模型和方法。重点在于风力发电机PQ特性的处理,将风电机组的有功表达为风速的函数,无功进而可以表示为有功、电压及转差的函数,并根据风电场节点电压与无功的关系,对雅可比矩阵进行修改,实现潮流计算与传统方法的并轨和一致性。应用模型和算法对风电接入后的烟台电网进行了计算分析,初步得到较满意的效果,也为进一步深入研究奠定了基础。 In this paper, some wind power generator models applied for power flow calculation are introduced, and a static model for the wind power farm is analyzed. The PQ model considering wind power generators characters is mainly researched. The model settled the wind power generators as a function of wind speed, so the inactive power can be represented as a function of active power and voltage. Jacobian matrix will be changed according to the relation of voltage and reactive power in the wind farm point. Applied with the model, the Yantai power system incorporated with wind power is calculated. The utility of the model is proved by the result. This can be the foundation of the future research.
