Performance Evaluation and Improvement of Three Terminal Differential Protection Scheme in Fast Fault Identification of Power System
With the continuous development of power system,rapid fault identification and isolation become especially important.As an important protection strategy,the three-terminal differential protection scheme plays a key role in power system fault identification.This paper introduces the basic principle of the three-terminal differential protection scheme,and then evaluates its performance in rapid fault identification,including identification speed,accuracy and anti-interference ability.On this basis,a series of improvement measures are proposed,such as introducing advanced signal processing technology,optimizing the protection algorithm,strengthening the construction of communication system and perfecting the fault recording function,in order to enhance the application effect of the three-terminal differential protection scheme in the power system.
