Embodiment Construction

[0060] The present invention will be further described below in conjunction with accompanying drawing.

[0061] In the description of the present invention, unless otherwise specified and limited, it should be noted that the term "connection" should be understood in a broad sense, for example, it can be a mechanical connection or an electrical connection, or it can be the internal communication of two elements, it can be Directly connected or indirectly connected through an intermediary, those skilled in the art can understand the specific meanings of the above terms according to specific situations.

[0062] Such as figure 1 As shown, it is a flow chart of a method for predicting the dynamic capacity of transmission lines based on fluid mechanics and meteorological data in the present invention. Since wind speed has the greatest impact on the capacity of transmission lines among many factors affecting the capacity of transmission lines, the prediction of line capacity in thi...

Abstract

The invention discloses a method for predicting the dynamic capacity of transmission lines based on fluid mechanics and meteorological data. the elevation data of the target area, and establish the geometric model of the target area; establish the complex terrain wind speed simulation model, and calculate the wind speed simulation results of the target area; use the time series analysis method to analyze the time series of the wind speed simulation results and the historical meteorological data, and predict the future time The predicted value of meteorological data; calculate the dynamic capacity value of the transmission line according to the predicted meteorological data; comprehensively consider the meteorological data and terrain, use the generated data to predict the future meteorological data, and calculate the capacity of the transmission line more accurately , which can give grid dispatchers a reliable reference.

Description

technical field [0001] The invention relates to the technical field of power grid transmission line capacity increase, in particular to a dynamic capacity prediction method for transmission lines based on fluid mechanics and meteorological data. Background technique [0002] With the rapid growth of the national economy, the transmission capacity of overhead lines in economic development has increased rapidly. The traditional method of increasing the capacity of transmission lines often requires huge investment, and rebuilding a line requires a lot of capital investment and time to complete, especially when land prices are high. In some areas, the economic benefits of rebuilding new lines are not obvious. In addition, a large number of renewable energy sources are connected to the grid. Improving the transmission capacity of lines is of great significance to protecting the environment and maintaining sustainable social development. [0003] The main environmental factors aff...
