【Abstract】 The necessity of reliability analysis in Agriculture Power network (APN) is set forth in this paper. Typical power supply network is used to introduee how to use the method of searching tree to search for the min-path and use the method of dual graph to search for the min-cut-set of the network. The formulas of these two methods,which are used to search out the reliability index in the network, are also presented. At last, with these methods, the reliable work probability index and failure rate index of main of wire splice of a typical substation in APN are worked out.更多还原
