针对放射状链式配电系统,应用无功功率、有功功率均可调的双馈风电机组进行潮流计算仿真。由于配电网络具有许多不同于高压输电网的特征,所以在算法上,本文应用改进牛顿算法。此方法可化简原雅可比矩阵,从而有效降低计算量。仿真结果表明,不同的风电机接入位置对潮流的收敛情况影响不大,却对系统网损有一定影响,大体上随接入点距离电网侧的距离增大而有减小趋势。另一方面,通过于常规异步风力发电机的比较,说明了双馈风力发电机的接入对馈线的电压分布具有明显的改善作用。

On radial chain distribution system,this paper solve power flow simulation with doubly fed wind power generator.As distribution network has many different from HV power transmission network,therefore,the paper use Improved Newton Algorithm.This method can be simplify the Jacobian matrix and effective reduce calculation.Simulation results show that different location of wind power generator access to have a small influence over the convergence of power flow,but have some influence over the Network Loss.Generally the influence of network loss reduced with the access point distance from the side of the Grid.On the other hand,voltage have remarkably improved when the Wind Power generator connected.
