摘要
针对牛顿拉夫逊法计算潮流时对节点电压初值的要求高的缺点,结合配电网为放射状网络的特征,提出基于前推回代法和牛顿拉夫逊法的配电网潮流计算,利用前推回代法第一次迭代的结果作为牛顿拉夫逊法的初值,能够满足牛顿拉夫逊法对初值的要求,且具有良好的收敛速度。最后,应用实例证明基于前推回代法和牛顿拉夫逊法的配电网潮流计算迭代次数少,收敛性好。
In allusion to the disadvantage of high requirement for initial value of Newton-Raphson method when flow calculation is carried on,and combining the open-loop radial structure features of power distribution network this paper proposes the flow calculation of power distribution network based on forward-backward sweep method and Newton-Raphson method.In this method,the first iteration result of forward-backward sweep method is taken as the initial value of Newton-Raphson method,which can meet the Newton-Raphson method's requirements of initial value with a good convergence speed.Cases show that the flow calculation of power distribution network based on forward-backward sweep method and Newton-Raphson method has fewer iteration numbers and good convergence.
