Wind measurement network layout method based on wind power plant layout in large-scale wind power base

Abstract

The invention discloses a wind measurement network layout method based on wind power plant layout in a large-scale wind power base. The method includes primarily distributing a point of a wind measurement network, wherein the distributed point serves as a weather forecasting point; building a weather forecasting model; obtaining forecasting values according to the built weather forecasting model and obtaining the wind speed and the wind direction of the forecasting point according to the built weather forecasting model; optimizing the wind speed and the wind direction of the forecasting point by reference to practical geography and topography conditions of the forecasting point on the basis of atmospheric boundary layer dynamics and boundary layer meteorological theories, and obtaining precise predicted values of the wind speed and the wind direction of the forecasting point; carrying out contrastive analysis on wind measurement data of multiple forecasting points with similar atmosphere environment and similar geography, simplifying multiple pre-built wind power base places with remarkable upstream and downstream effects and strong correlation, and therefore finishing wind measurement network layout. Therefore, the aim of providing anemometer tower distributing points for wind energy resource measurement in the large-scale wind power based on low cost conditions is effectively achieved.

Description

technical field [0001] The invention relates to a wind measurement network layout method based on the wind farm layout of a large-scale wind power base. Background technique [0002] At present, in recent years, with the continuous maturity of wind power generation technology, the wind power industry has developed rapidly. The installed capacity of domestic wind turbines and the proportion of on-grid electricity continue to increase, and the construction scale and number of wind farms are also increasing significantly year by year. Wind power developers began to pay attention to wind resources and seize wind resources, and invested in setting up wind measuring towers in areas rich in wind resources to obtain first-hand wind energy data for future investment and construction of wind farms. [0003] In the development and utilization of wind energy resources, the anemometer tower is in a very important position, mainly in the wind resource assessment in the early stage of the...

AI Technical Summary

Problems solved by technology

It has caused problems such as unrepresentative selection of wind measurement towers and difficulty in wind measurement network layout.

Due to the lack of effective theoretical support, for the entire wind power base, the distribution of wind measurement network is even more difficult to grasp.
