Research on Self-Healing Mode of Communication Channel of Regional Power Grid Stability Control System

Abstract

Abstract Under the new situation of large power grids, security and stability control systems and their communication channels are facing new changes and new requirements. The article proposes a smart grid dispatching control system multi-channel information intelligent comparison method, through the network monitoring method to obtain the main plant station information interactive communication message, using the intelligent comparison algorithm to compare remote signalling, telemetry, sequence of events (SOE), Communication protocol parameters such as remote control and remote adjustment are compared, and alarm events are output in time according to the comparison results. By combining the principle of the stability control device and the principle of communication self-healing, the influence of the stability control channel communication self-healing ability on the operation of the stability control device is analysed, and the influence of whether self-healing is adopted in operation is analysed. Based on the comparison, it is concluded that the communication channel of the regional network stability control system should use self-healing method.
