Weather forecasting method and system for transformer station

Abstract

The invention provides a weather forecasting method and system for a transformer station. The method includes: obtaining meteorological factor information of N meteorological stations within a preset area range, wherein the meteorological factor information comprises the meteorological factor values Z (xi) observed by the meteorological stations, xi represents for any one meteorological station in the N meteorological stations, and i= 1...N; rejecting the wrong meteorological factor values in the meteorological factor values Z (xi), and reserving the right meteorological factor values Z (xi)'; and calculating the meteorological factor values Z (x) of the transformer station according to a formula shown in the description, wherein lambda i represents for the pre-calcualted reverse distance weight coefficient of the transformer station corresponding to the meteorological stations or ordinary Kriging weight coefficient of the transformer station corresponding to the meteorological stations. The weather forecasting method and system solve the problem that the weather forecast error is large caused by the fact that the weather conditions of the surrounding environment are forecasted objectively in the prior art, and accordingly accurate weather forecast of the surrounding environment of the transformer station is achieved.

Description

technical field [0001] The invention relates to the technical field of weather forecasting, and more specifically, to a weather forecasting method and system for power stations. Background technique [0002] Power grid is an important infrastructure related to national energy security and social public safety. With the development of national economy and society, the scale of power grid continues to expand. In the context of global warming, extreme meteorological disasters occur frequently and reoccur, and the impact on the safe operation of the power grid is becoming more and more obvious. Therefore, timely and effective forecasting of the meteorological conditions around the substation is carried out to provide timely and effective meteorological observation information and early warning for each substation. Information is of great significance to grid security. [0003] At present, the geographical distribution of most meteorological observation stations and substations ...
