关于33节点的配电网潮流计算程序C++版本(Distribution network power flow calculation program of 33 nodes on the C version)

说明：   M-file for Project 1 on line parameters and circuit models in Chapter 3 m1.m determines the RLC parameters of the line from its physical description and then computes the ABCD matrix and the circuit parameters of the series RL, nominal pi and equivalent pi model of the line. It computes and plot the receiving-end real and reactive power circle diagram of the line assuming that the voltage magnitude at the sending- and receiving-end are kept constant.
