摘要
设计了一种复杂中压配电网可靠性评估的通用模块,以馈线为基本单位,无需简化等值,利用深度优先搜索算法和广度优先搜索算法进行拓扑搜索。提出了基于受故障影响相同的面向断路器的一级分区以及基于相同故障影响的面向隔离类开关的馈线二级(最小化)分区,一次性形成由各分区构成的系统正常供电区域,可操作恢复供电区域和不可操作恢复供电区域。模块基于AutoCAD可视化界面,采用ObjectARX二次开发技术进行数形一体化建模,结合大型数据库,以实际配电网络为例,快速地评估系统可靠性指标并找出薄弱环节,证实了其有效性和工程实用性。
A general reliability evaluation algorithm for complex medium voltage distribution networks （MVDNs） is proposed,in which each feeder is a basic unit and without simplifying the network equivalent,the depth-first search algorithm and breadth-first search algorithm are used to search each feeder in topologies. T hen circuit breakers oriented first-class zone based on the same influences by the failure and isolating switches oriented feeder second-class which is also the minimum zone based on causing the same failure impact are formed.System＇s normally power supply area,system＇s operational recovery of power supply area and system＇s unoperational recovery of power supply area can be formed by each at one time. Based on the AutoCAD visualization platform,and using ObjectARX secondary development technique and large-scale database ,t he paper has completed the design and implementation of reliability evaluation module under the graphical interface applications.T he module has been tested on the practical MVDNs to calculate the system reliability index quickly and find out the weak link,which verifies the effectiveness and the practicability of the proposed methods and applications in practical engineering.
