电力系统故障计算，可以计算单相短路，单相接地短路，三相短路，两相短路接地，两相短路(power system fault, can calculate the single-phase short circuit, short-circuit to the single-phase and three-phase short-circuit, two-phase short-circuit grounding, two phase short circuit)

m file for a example of GA,using with matlab tool,wish it is useful for you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

R/S分形计算H指数，可以替换成自己的数据，很方便(R/S calculation of the fractal index H can be replaced by their own data, it is convenient)
