该C程序的主体框架是根据《现代电力系统分析》（王锡凡）的附录PQ分解法潮流程序来完成的，并采用BX方案。程序中采用了快速解耦潮流计算方法和稀疏矩阵存储技术，并对程序的主要算法进行了子程序编制。本程序认为迭代次数超过1000次即为不收敛，并给出了五节点五支路系统data5.dat作为示例。-The C program of the main framework is based on " Modern Power System Analysis"　(Xi-fan) the trend of the appendix PQ decomposition process to complete and adopt the BX program. Procedures used in the fast decoupled power flow calculation method and sparse matrix storage techniques, and procedures for the preparation of the main algorithm subroutines. That the number of iterations of this procedure shall be not more than 1000 times the convergence, and gives the five-node five-branch system data5.dat as an example.
