Power Grid Resource Early Warning Strategy Based on Mutation Identification

Aiming at the passive operation and maintenance mode of alarm and repair after the occurrence of power grid resource failure, a power grid resource early warning strategy based on mutation identification is proposed. The strategy includes the steps of power grid resource data aggregation, similar resources analysis, historical data research and judgment, sub-strategy fusion and comprehensive early warning research and judgment. A sub-strategy for early warning of similar resources including real-time judgment algorithm and historical similar day judgment algorithm is designed. Based on the steady-state jump warning and steady-state fluctuation warning method, a sub-strategy for judging and warning the historical data of power grid resources is designed. Through sub-strategy fusion and comprehensive early warning research and judgment, the state mutation of power grid resources is identified, and the active early warning mode of power grid resources based on prevention is realized to improve the reliability of power supply.
