In order to fulfill the study demand of TCSC protective relay, this paper discusses how to build the detail and real digital simulation models. Firstly, the TCSC circuit and its conventional controller used in mechanical and electric transient analysis are introduced, and the effects on relay system are discussed. Then the paper puts the emphasis on analyzing the digital simulation demands of the protective relay and technical outlines of building the simulation models. The detail method of building feedback simulation model is presented. Finally the concrete simulation scheme and computation examples are given.
