Development of a Modern Contactless Version of the Control and Monitoring Relay Block (P62) in the Electrical Centralization System and Creation of its Mathematical Model

This article is dedicated to the modernization of the control and monitoring relay block (P62) in the electrical centralization system using modern contactless elements, as well as the development of its mathematical model. The operation of the P62 block on train and shunting routes has been analyzed, and its holding algorithm has been developed. During the development of the upgraded TP62 block model, the input, output, and relay operation functions of the existing P62 block were created. Based on these functions, the TP62 model was developed using the $C \#$ programming language in the Visual Studio application, and its operation was simulated using this software.
