Feeder Terminal Unit Model Based on Electromagnetic Transient Simulation Platform

The feeder terminal unit (FTU) is the core equipment for realizing power distribution automation. In this paper, the logic function model of the feeder terminal unit is established based on the electromagnetic transient simulation platform. First of all, the functions of the feeder terminal unit are clarified, including measurement, protection and control functions. Then, the action logic of the feeder terminal unit is designed, and the power distribution terminal model is established by using the logic custom module of the electromagnetic transient simulation platform. Finally, a simple distribution network model is established to verify the rationality of the parameter configuration of the feeder terminal unit model established in this paper and the action logic of the coordination of multiple feeder terminal units. The model serves as a simulation reference for the actual feeder terminal unit to put into operation the distribution network, which is beneficial to improve the power supply reliability of the distribution network.
