配电网自动化中面保护的研究

Research on Area-protection in Distribution Network Automation

通过对馈线保护方式进行研究,对配电保护的现状进行了分析,并对配电保护中面保护的定义、原理以及算法进行具体阐述。通过对馈线保护硬件及软件的设计,模拟现实情况,对该方法进行了模拟仿真,仿真结果显示这种基于面保护方式的馈线保护方法,利用完整的通信网络和安装于柱上开关上的配电终端来实现配电保护,可以有效地将故障定位并隔离,使故障恢复得更加迅速,提高了我国配电网的可靠性。

Studied by means of feeder protection,this paper analyzes the present situation of the power distribution pro-tection,and protection for distribution in the surface protection of the definition,principIe and aIgorithm.Through to the feeder protection hardware and software design,simulation reaIity,has carried on the simulation to this method, the simulation result shows that the feeder protection method based on surface protection way,using integrated communication network and in-stal ed in the column on the switch on the power distribution terminaI to reaIize the power distribution protection.
