摘要:

通过配电网终端的信息交互,实现配电网智能自愈可以提升供电可靠性,减少故障引起供电中断时间。配电网自愈系统的终端数量较多,而且分布在不同的配电网节点,出厂验收和现场调试的复杂困难程度较高。提出一种分布式配电网自愈系统的测试方法,利用多台测试仪相互交互各自节点的断路器位置,拓扑配电网结构并判断不同配电网节点的模拟量状态,完成对配电网的简易仿真。所提方法的计算复杂度低,适合嵌入式测试仪的快速计算,验证表明在同步性等技术参数上符合配电网自愈测试的需要。

Abstract:

The intelligent self-healing of distribution network can improve the reliability of power supply and reduce the interruption time of power supply caused by faults through the information interaction of distribution network terminals.There are many terminals in the self-healing system of distribution network,so it is very difficult to verify the nodes in different distribution network.In this paper,a test method and system were proposed,which uses multiple test equipment to interact with each circuit breaker state,topologize distribution network structure and judge the analog quantity status of different distribution network nodes to complete a simple simulation of distribution network.This method has low computational complexity and is suitable for the fast calculation of the embedded tester.It was verified that it meets the needs of the self-healing test of distribution network in terms of technical parameters such as synchronization.

Key words: self-healing test of distribution network, distribution network simulation, distribution network topology, test equipment
