基于CYME的配电网可靠性评估应用

Reliability Assessment Application of Distribution Network Based on CYME

配电网供电可靠性直接影响用户的用电质量,应用电力系统分析软件CYME,对配电网进行建模分析。研究比较了不同供电半径和不同典型结构配电网的供电可靠性,并针对实际配电网算例,分析了不同开关动作时间下的配电网可靠性的情况;从各个负荷点可靠性的角度,寻找出该配电网中可靠性较差的负荷点,进而提出了具有针对性的网架优化方案,为配电网可靠性评估分析及应用提供了参考。

The distribution network power distribution reliability directly impacts on users’power quality.This paper adopted the power systemsoftware CYME to carry out the power network modeling analysis and researched on the power distribution reliability of different power supplyradius and different typical network structures.Aiming at an actual power distribution network example,this paper analyzed the power distributionnetwork reliability situation of different switch actuation time.From the reliability corner of each load point,this paper found the load point of inferiorreliability in the distribution network,proposed a specific net rack optimization scheme,which provides references for the reliability assessmentanalysis and application in the distribution network.
