牛顿-拉夫逊法潮流计算
基本步骤:
(1)形成节点导纳矩阵
(2)将各节点电压设初值U,
(3)将节点初值代入相关求式,求出修正方程式的常数项向量
(4)将节点电压初值代入求式,求出雅可比矩阵元素
(5)求解修正方程,求修正向量
(6)求取节点电压的新值
(7)检查是否收敛,如不收敛,则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代,否则转入下一步
(8)计算支路功率分布,PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)
