Example Embodiment
[0032] Example 1:
[0033] On November 6-9, 2015, a large-scale severe icing process occurred in Liaoning Province. Taking Dalian City as an example, using the present invention to take into account the solar radiation in the northern area power grid icing numerical prediction correction method, the icing process The numerical forecast is revised, the specific steps are as follows:
[0034] (1) Weather data collection. From the local weather station's weather forecast on November 6, 2015, collect real-time ground and high-altitude weather data and forecast weather data for that day, including precipitation data and temperature data.
[0035] (2) Collecting icing data. Collect the actual icing information of transmission lines on November 6, 2015 in Liaoning Province and the numerical forecast information of icing on transmission lines on November 7-12, 2015:
[0036] On November 6, 2015, the icing areas of transmission lines were Dalian and Yingkou;
[0037] Numerical forecast result...
Example Embodiment
[0067] Example 2:
[0068] On November 23-24, 2015, an ice-coating process occurred in Henan Province. Using the method of the present invention to correct the numerical forecast of the ice-coating process in the northern region of the grid considering solar radiation, the numerical prediction of the ice-coating process was corrected. The specific steps are as follows:
[0069] (1) Weather data collection. From the local weather station's weather forecast on November 22, 2015, collect real-time ground and high-altitude weather data and forecast weather data for that day, including precipitation data and temperature data.
[0070] (2) Collect icing data. Collect the actual icing information of transmission lines on November 22, 2015 in Henan Province and the numerical forecast information of icing on transmission lines on November 23-26, 2015:
[0071] On November 22, 2015, there was basically no icing on the transmission line;
[0072] Numerical forecast results of icing on transmissi...
