摘要
提出了一种保留潮流方程泰勒展开式二次项的快速潮流计算方法,采用因子表解法和重叠原理求解修正方程,作为节点功率同型异变量的二次项可直接由修正方程式的常数项决定,整个迭代过程无需进行节点功率计算,且便于处理PV节点无功越限.该方法对模型未作任何简化,对支路电阻和电抗R/X不敏感,特别适合于配电网络的潮流计算.
A calculation of fast load flow including second order terms in the Taylors series expansion of the load flow equations is presented. The triangular factorization and the superposition theory are adopted to solve revised equations. Having the same form as computed complex power injection, the second order terms are directly obtained by utilizing the constant terms in revised equations, and the complex power injection computing is no more needed during the iteration process, and handling Q violation of PV bus is very simple. The method, being applicable to distribution networks especially, is accurate and not sensible to the ratio of R/X .
