电力系统潮流程序，包括高斯赛德尔迭代、牛拉法、PQ法、保留非线性法，有注释和说明文档，IEEE5节点系统-Power Flow program, including G-s & NL & PQ & nonlinear method, notes and documentation, IEEE5 node system

有限容积法对非稳态传热偏微分方程进行离散，方程组的求解采用高斯-赛德尔迭代法- differential equation were discretized by an implicit finite-difference method, and the aforementioned simulative equations were solved numerically using the Gauss-Seidel method
