Research on Multi Point Self Healing Technology of Optical Channel Based on Wide Area Stability Control and Proposal of Reducing Business Risk Optimization Model

In order to reduce the operation risk of the network and improve the self-healing ability of the real-time wide area control system, this paper presents a link break analysis model of power communication network. This model is based on the research and optimization of multi-point fault self-healing technology about the light channel and combined with the recovery method of single point of failure. According to the definition of risk assessment and the automatic rerouting of basic mechanisms which is based on ASON, the corresponding rerouting triggering mechanism and optimization model is proposed. This measure effectively reduced the operational risk of the business, then further strengthened the robustness and stability of the real-time wide area secure control system that finally ensure the stable and reliable operation of the communication network and the power grid system.
