一种配电网环型供电模型及其合环运行方式的研究
Study on a Loop Power Supply Model and Its Loop-close Operation Mode for Distribution Network
摘要
Abstract
With the development of medium voltage distribution network, a reasonable network plan takes an important role in improving the supply reliability and power quality. Taking it as the aim, a loop power supply model based on switching stations hand in hand was proposed to increase the flexibility of operation mode, the capability of load transfer and the expansibility of structure in distribution network. In order to reducing the short-circuit current brought by loop-close operation, through analyzing the short-circuit transfer impedance, a loop-close operation mode for the proposed loop power supply model was explored based on installing short circuit current limiters on the low voltage side of transformers , splitting substation low voltage buses and the switching station buses. In the end, the distribution network for Kaili city, Guizhou province, in 2015 was designed by using the proposed loop power supply model. At the same time, the feasibility of the distribution network adopting the presented loop-close operation mode was demonstrated as well. The research results not only show the effectiveness of the proposed loop power supply model and loop-close operation mode, but also indicate that it has pretty application value to the plan of distribution network construction.关键词
