Design of 500 kV Substation Relay Protection Device Renovation System Based on Original Screen Scheme
In the power system,500 kV booster stations play a crucial role,and their relay protection devices can ensure that the system can reliably,quickly,and accurately cut off the faulty part in the event of a fault,ensuring the safe and stable operation of power plants and the power grid.With the development of technology,traditional relay protection devices are gradually unable to meet the needs of modern power grid development,and their performance and intelligence level need to be improved through technological transformation.The transformation based on the original screen solution,which involves upgrading and optimizing existing equipment and architecture,is an economical and effective strategy.This transformation not only involves the upgrading of hardware,but also the advancement of software and system integration technology,especially in the application of digital protection and intelligent control.This paper provides a detailed introduction to the design of the renovation system for the relay protection device of a 500 kV substation based on the original screen scheme,covering the realization process from the system architecture,digital protection and intelligent control,to the system integration design and the renovation design,the renovation plan,technical applications,and expected results are comprehensively elaborated.
