摘要
针对变电站刀闸存在操作顺序错误的问题,采用间隔层五防系统解决该问题。首先分析了间隔层五防系统的原理,然后对防误系统进行建模,建立了虚端子连接关系,分析了防误系统操作流程,最后根据模型设计了间隔层五防逻辑文本,并应用于变电站工作中。现场试验和调试表明,所设计的间隔层测控五防能有效进行刀闸防误操作,对变电站防误具有重要的作用。
There is a problem of incorrect operation sequence of the knife switch in the substation,and the Five Protection system of the Bay layer is used to solve the problem.Firstly,the principle of the Five Protection system of the Bay layer is analyzed.Then,the error prevention system is modeled,the virtual terminal connection relationship is established,and the operation process of the error prevention system is analyzed.Finally,the Five Protection logic text of the Bay layer is designed according to the model and applied to the work of the substation.The field test and debugging show that the designed Five Protection of bay layer measurement and control can effectively prevent the wrong operation of the switch,and plays an important role in the wrong prevention of the substation.
