P-Q潮流计算简单实现,10阶以内均可计算,算例可参考<<电力系统稳态分析>>,东南大学,第二版,174-178页.-P-Q trend is simple to achieve, within 10 bands can be calculated with reference counting

PQ分解法，有些还需要改进，该程序所对应的例子是东南大学陈珩编的《电力系统稳态分析（第二版）》的例4-5-PQ decomposition, some also needs to be improved, The procedure corresponding to the example of Southeast University, Chen Heng addendum to the "steady-state power system analysis (second edit
