Abstract: Traditional relay protection technology faces the problem of insufficient response speed. This paper elaborates on the basic principle of the PID controller and explores its parameter adjustment methods to ensure optimal control under different operating conditions. Combined with experimental verification and fault data analysis, the response of different fault types is analyzed. The improved PID controller can effectively reduce the number of trips and improve the stability of the relay protection device.
