低压供电可靠性故障及修复仿真研究

Simulation and research of Fault & Repair in low-voltage power system reliability

随着电力系统的发展,人们对供电可靠性的要求也越来越高。如何统计现有条件下的用户供电可靠性,是大家比较关注的问题。本文根据低压系统的网络特点和组件的具体物理特性,结合概率论和数理统计的方法,运用计算机模拟仿真技术,根据组件故障与修复时间服从的分布,实现对低压用户供电系统故障产生与修复时间的模拟,以期对供电可靠性统计方法进行验证。

With the development of electric power system, the requirement of people for the electric power supply reliability is getting higher and higher. How to evaluate the power supply reliability is one of people＇s main concerns, Considering the characteristic of power system networks and the specified physical characteristic of components, combined ,with the theory of probability and mathematical statistics, this paper is based on the distribution of component fault and repair-time. Using the computer simulated techniques, it realizes the simulation of fault happening and the simulation of fault component＇s repair-time in low-voltage power supply system .It is also expected to verify the method of getting electric reliability by statistics means.
