Research of Current Instantaneous Trip Protection Based on Adaptive Control

YAN Bo(Anhui Electrical Engineering Professional Technique College, Hefei 230051, China)  
The common current instantaneous trip protection relays can not auto-identify the operating mode of system, and the different types of fault-clearing patterns of power distribution line. With the development of automatic control theory, adaptive control system appeared. This paper introduces a new method of set point auto-turning, it has a great importance for improving the sensitivity of protective relays.
