Research And Application Of Debugging Method For Secondary Equipment In Intelligent Substation

The debugging of the secondary system of intelligent substation involves two parts,indoor and outdoor.Under the current debugging mode,the number of people,the time of debugging and the cost of debugging are generally high.To solve this problem,this paper studied the debugging method of the secondary system of intelligent statioaFirst,the structure,configuration and debugging of intelligent substation secondary system were studied.Then the networking debugging method was proposed.The basic principle of a network alignment schehe was analyzed from single interval,sevral intervals and acrossing intervals.The network structure,working principle and applicable scene of each method were analyzed in detaiL It pointed out that debugging the host was the core content of networking debugging method to realize centralized control of all testers.Secondly,the comnunication network of networking debugging method of intelligent station secondary system was designed,and three networking modes of R45 network,optical fiber network and wireless network were proposed.The network structure,working principle,advantages and disadvantages were analyzed,and the communication network with wireless network as the main part and optical fiber network as the auxiliary part was determined.Finally,the engineering application of networking debugging method was analyzed jfrom the total number of choose and enploy persons,total available time,total cost of debugging,action time,economy benefit and management benefit.The analysis results showed that the network debugging scheme in the total number of choose and employ persons,total duration and total cost of debugging was significantly superior to the conventional debugging scheme,which confirmed the effectiveness of the proposed network debugging method.It can provide guidance for secondary equipment debugging of intelligent station.
