广西中压配电网接线模式探讨分析

Discussion and Analysis on Connection Modes of Medium Voltage Distribution Network in Guangxi

中压配电网是可靠供电关键环节,接线模式关系到中压配电网的可靠性。笔者通过分析中压配电网典型接线模式的优缺点及适用范围,借鉴国外典型供电模型,结合广西地域特征和负荷特征,对广西中压配电网网架设计进行了探讨,并提出广西中压配电网不同发展阶段的接线模式建议。研究表明,采用分阶段建设中压配电网的方式可以满足广西供电需求和智能电网的发展。通过采用中压配电网灵活的接线模式,并逐步实施配电网自动化,可提高中压配电网的供电可靠性和运行维护水平。

Medium voltage distribution network is the key link of reliable power supply,and the connection modes is related to the reliability of medium voltage distribution network.Based on the analysis of the advantages and disadvantages of the typical connection modes of the medium voltage distribution network and theirs application scope,and referring to the typical foreign power supply model,combined with the regional characteristics and load characteristics of Guangxi,the author discusses the design of the medium voltage distribution network framework in Guangxi,and puts forward the connection modes suggestions in different development stages of the medium voltage distribution network in Guangxi.The research shows that the construction of medium voltage distribution network in stages can meet the demand of Guangxi power supply and the development of smart grid.By adopting the flexible connection modes of medium voltage distribution network and gradually implementing the automation of distribution network,the power supply reliability and operation maintenance level of medium voltage distribution network can be improved.
