Misuse of electrical substation equipment will be a serious threat to security and stability of power system operation, can cause blackouts, power equipment damage, system oscillation collapse, or even personal injury. To prevent accidents caused by misuse of electrical equipment in China in 1990, raised by the electrical equipment "five anti" requirements, and regulations in the form language of the provisions of the electrical anti-error management, operation, design and use principles. With the development of power systems, five anti-lock technology is continuously updated, China has experienced a mechanical latch, latch mechanical process, electrical locking, five anti-PC, anti-integration of five, five-line anti-technology, anti-mislock way these have their own characteristics, the application of different occasions. Crossed the 21 century's first decade, computer technology, electronic technology, communication technology, signal processing technology has made rapid progress, substation automation experience from scratch, from the initial stage to the advanced stage of the development process. This paper will combine the Guangdong Power Grid Corporation of the actual operation of the substation to introduce a variety of five anti-technology in substation applications, focuses on five anti-PC and anti-in-line five substation applications.
