Transmission Line Relay Protection Fault-Tolerant Information Sharing and Joint Analysis Method

Aiming at the problems of low information fusion and slow real-time protection of traditional transmission line relay protection methods, a fault-tolerant transmission line relay protection method based on the concept of three-type and two-network is proposed, which divides the grid into correlation domains, calculates the actual current by using the charge variation coefficient, establishes the protection matrix according to the complexity and logic of the fault, calculates the differential of the current, and refers to the concept of “shared type” to establish a new method of information sharing and joint analysis of transmission line relay protection. Shared” concept, to establish a new method of transmission line relay protection fault tolerance information sharing and joint analysis, introduce the use of the method to control the discharge gap of the transformer, non-singular matrix and gain matrix to establish the set of conventional control rate and fault automatic repair control rate, set the actual fault tolerance control rate, to realize the improvement of transmission line relay protection fault tolerance method, and through the test results and comparison with the traditional method, it is shown that the proposed transmission line relay protection fault tolerance method has been improved, and the proposed method can be applied to the transmission line relay protection. The experimental results and comparison with the traditional method show that the proposed transmission line relay protection fault tolerance method is more perfect.
