Research Of DTS And Relay Protection Simulation In Local Grid

This paper mainly research on DTS in local grid and simulation of relayprotection. Firstly the characteristic of DTS in local grid is analyzed and the system of DTSincluding hardware and software based on SCADA/EMS/DTS is designed.Secondlythis paper works over several key issues of simulation of relay protection And thengeneral relay model and data structure are designed . To resolve the realtime problem of simulation,the method of relay tree is putforward.By this means we develop the program of logical comparison andquantitative comparison. It proves to be of good expansibility and agility by experiment.The result ofsimulation is fast and accurate ,which reaches the requirement of relay protectionsimulation.
