摘要
针对变电站发生全停后开关状态无法识别而引发的问题,提出一种考虑配网实时运行方式的负荷转供技术.采用贝叶斯网络描述开关状态与节点电压的关系,识别配网的拓扑运行状态进而作为转供方案的基础.最后通过对某个实际配电系统的故障仿真分析,结果表明该方案可以有效提高停电负荷的转供能力.
Abstract
Aims at the problem that the switch state cannot be identified after the complete shutdown of the substation,this paper proposes taking into account the frequent topology changes.Bayesian networks are used to describe the relationship between switch status and node voltage,identify the topology of the distribution network,and serve as the basis for the power transfer scheme;Finally,through fault simulation analysis of an actual distribution system,result can effectively increase the transfer capacity of power outage load.
