基元构建配电网接线方式的可靠性分析

扫码查看
配电网的可靠性是电力系统可靠性三大组成部分之一,配网接线方式是影响其可靠性的一个重要因素.对中压配电网接线模式进行高度抽象和概括,结合配电网网络等值分析法、数学集合理论,建立接线模式的图形模型和数学模型,提出一种基于基元的构建配电网接线方式的方法,并对其进行可靠性分析.最后,通过一个算例说明该方法的正确性.
Reliability Analysis of Distribution Network Wiring Method Based on Element
The reliability of distribution network is one of the three elements of power system reliability,and the wiring method is an important factor for the distribution network reliability.In this paper,the wiring method of medium voltage distribution network is generalized.In combination with distribution network equivalent analysis and coalition theory,the graphical model and mathematical model for wiring method are built.A new wiring method based on element is presented,and its reliability is analyzed.Finally,a calculation example has verified the reliability of the proposed method.
