配电网的可靠性分析

Fail-Safe Analysis of the Ditribution Network

随着国民经济的迅速发展以及人民生活水平的不断提高,电力用户对供电可靠性的要求越来越高,因而需要对供电系统的可靠性加强管理。配电系统是直接连接电网和用户的关键环节,直接影响对用户的供电质量,因此配电系统的可靠性研究有重要意义。基于此,首先分析了串、并联系统的可靠性模型,又分析了配电网的可靠性指标和经济效益评估指标,最后介绍了几种提高配电网可靠性的措施。

With the rapid development of national economy and the people＇s living standards improvement, and power users to demand more and more power supply reliability, and the need to strengthen the management of the power supply system reliability. The power distribution system is connected directly to the key link of users and power grids, directly affects the quality of power supply to the user, so the distribution of the reliability of the system research has important sense. Based on this, the first analysis of the series and parallel system reliability model, and analyses the distribution network reliability indices and economic benefit evaluation index, at last, the paper introduces several distribution net- work reliability measures.
