摘　　要：针对风力发电厂的孤立网架结构完整的系统,研究了分布式风力发电并网对电力系统潮流分布的影响。从电气工程领域的角度详细分析了风力发电机组的结构、工作原理,建立了风电机组异步发电机简化等值电路模型。通过牛顿拉夫逊潮流计算思路,提出了含风电场的电力系统潮流计算方法,并联合迭代法修正了雅克比矩阵,解决计算精度与迭代效率之间的矛盾;针对IEEE 14节点系统开展算例分析,获得风电并网对电力系统潮流分布的影响。通过对一含风电的IEEE 14节点系统进行潮流计算,验证了该方法的可行性,成果可应用于含风电场的电力系统潮流计算场景。In this paper,the influence of grid connected distributed wind power generation on power system power flow distribution is studied.From the perspective of electrical engineering,the structure and working principle of wind turbine are analyzed in detail,and a simplified equivalent circuit model of wind turbine asynchronous generator is further established.The power flow calculation method of power system with wind farms is proposed through Newton Raphson power flow calculation idea,and the Jacobian matrix is modified by joint iteration method to solve the contradiction between calculation accuracy and iteration efficiency.An example analysis is carried out for IEEE 14 bus system to obtain the impact of wind power grid connection on power system power flow distribution.The correctness and feasibility of this method are verified by the power flow calculation of an IEEE 14 bus system with wind power,and the results can be applied to the power flow calculation scenario of power systems with wind farms.
