MATLAB实现对该系统的潮流计算。需要MATLAB语言编制程序形成节点导纳矩阵、形成雅克比矩阵、用高斯消去法解修正方程式，并编写输出程序用以输出节点导纳矩阵、节点电压（包括电压的相角和幅值）、以及各支路的首端功率、末端功率和功率损耗(MATLAB implementation of the system flow calculation. MATLAB programming language requires the formation of the node admittance matrix, Jacobian matrix formed by modified Gaussian elimination method for solving equations, and write out procedures for the admittance matrix of the output node, the node voltage (including the voltage phase angle and amplitude), and the first end of each branch of power, end power and power loss)
