中压配电网典型接线模式可靠性影响因素分析
|
摘要
介绍了国内中压配电网的架空线典型接线模式和电缆线典型接线模式,以苏州某地的系统参数为例,利用DIgsilent/Powerfactory软件计算各典型接线的供电可靠性指标,平均供电可靠率(ASAI)和系统年平均缺供电量(ENS-LP)两大系统指标作为供电可靠性分析的指标依据,分析了线路分段情况、负荷均衡度、负荷密度及配电自动化等对中压配电网的7种典型接线模式供电可靠性的影响,分析结果可为相关行业人员提供参考。
Introduction was made to the typical connection modes including overhead line and cable line of domestic medium voltage distribution network. Taking the system parameters of somewhere of Suzhou as an example, this paper used the software DIgsilent/Powerfactory to calculate the power distribution reliability index of various typical connections. The average service availability index(ASAI) and the system ENS-LP were taken as the indexes basis of power distribution reliability to analyze the influence of line segment, load balance, load density and distribution automation on power supply reliability of 7 kinds of typical connection modes in medium voltage distribution network.The analysis result provides references for the related industry personnel.
