Comprehensive management method and system for meteorological and power data

Abstract

The invention discloses a comprehensive management method and system for meteorological and power data. The method includes the following steps: acquiring the meteorological data of an area where a power grid system is located and the power grid data of the power grid system at the same time in advance, and carrying out multivariate linear fitting on the meteorological data and the power grid datato obtain a meteorological-power grid model characterizing the corresponding relationship between the meteorological data and the power grid data; acquiring the future meteorological data of the areawhere the power grid system is located in real time according to a meteorological prediction system, and combining the future meteorological data with the meteorological-power grid model to predict the future power grid data of the power grid system; and calculating the difference between the future power grid data and preset reference power grid data, and determining the degree of influence of future meteorology on the power grid system according to the magnitude of the difference. The method and the system of the application can be used to automatically determine the degree of influence offuture meteorology on the power grid system, and the determination result is accurate. Therefore, pre-protection measures can be taken for the power grid system according to the determination result,and the security and reliability of the power grid system are improved.

Description

technical field [0001] The invention relates to the fields of meteorological systems and power grid systems, in particular to a comprehensive management method and system for meteorological power data. Background technique [0002] With the development of meteorological science and technology, the forecasting system for weather conditions is becoming more and more accurate. The meteorological forecasting system is based on the meteorological observation data, and applies the principles and methods of synoptics, dynamic meteorology, and statistics to make qualitative or quantitative forecasts of the weather conditions of a certain area or a certain place in the future for a certain period of time. At present, because the weather in the area where the grid system is located will affect the stability of the grid system, grid managers often refer to the future weather in the area where the grid system is located as predicted by the weather forecasting system to make simple predi...

Problems solved by technology

However, the prediction method of the stability of the transmission line of the power grid system requires experienced power grid managers, which is time-consuming and laborious; moreover, even for experienced power grid managers, the prediction results of the stability of the power grid system transmission lines are not consistent with future There is a large deviation in the actual impact of the weather on the power grid system, so that more effective preventive measures cannot be taken, which in turn reduces the safety and reliability of the power grid system
