Zoning-Prediction-Response (ZPR) Monitoring and Early Warning Model for Thunderstorms in Power Grid

Thunderstorm is a strong convective weather, and it is one of the main meteorological disasters leading to circuit failure. This paper builds a reliable model of distribution lines in thunderstorm weather, quantifying the influence of thunderstorms on power supply reliability of distribution grid, and forming a set of reasonable disaster pretreatment schemes. Based on the relationship between the characteristic variables of thunderstorms meteorological parameters and the risk of line lightning outage, we establish Zoning-Prediction-Response (ZPR) monitoring and early warning model to provide real-time operation risk of distribution grid. At the same time, a reasonable solution can be obtained through the interaction with the power system security and stability analysis software. Finally, in the evaluation experiment of early warning effect, the prediction accuracy rate of this model for thunderstorms is more than 60%, and the prediction accuracy rate of grid failure rate reaches 92.3%, indicating that this model has good accuracy in predicting grid thunderstorms disaster.
