Interval integration design for in situ relay protection of transformer substation

Abstract

Abstract:

Facing the in situ integration demands of relay protection of transformer substation, this paper carried out integration and optimization design for the relay protection devices of medium and high voltage lines in transformer substation, which integrated distributed bus protection, merging units, intelligent terminals, measuring and controlling function, etc. This design scheme mainly adopted the methods of physical integration of devices and independent functional modules. Through analyzing and testing, this design scheme could improve the reliability and realtime performance of protection sampling, reduce the number of devices and cabinets, increase information processing efficiency and simplify wiring in smart substations.
