中文说明： 这个程序是基于蒙特卡洛算法，用于评估发输电系统的可靠性，通过蒙特卡洛抽样，间接模拟发输电系统的运行状态，求取特定的指标，从而计算系统的可靠性指标。本文程序是电力系统IEEE经典的39个节点的分析，程序分为五大部分。
English Description：
&This program is based on Monte Carlo algorithm, which is used to evaluate the reliability of the power generation and transmission system. Through Monte Carlo sampling, it can indirectly simulate the operation state of the power generation and transmission system, obtain specific indicators, and then calculate the reliability indicators of the system. This program is the IEEE classic 39 node analysis of power system, the program is divided into five parts.
