Abstract

The invention discloses a wind power plant wind resource calculation method, a device, equipment and a computer readable storage medium, and the method comprises the steps: taking meteorological reanalysis data as a background field of a mesoscale WRF mode, carrying out the numerical simulation of a defined region through the mesoscale WRF mode, and obtaining mesoscale meteorological analysis data; extracting meteorological analysis data from the mesoscale meteorological analysis data, and reconstructing the meteorological analysis data; taking the reconstructed meteorological analysis data asan inflow boundary condition of a micro-scale CFD model, and performing numerical calculation on the wind power plant area by utilizing the micro-scale CFD model to obtain a calculation result; and obtaining a wind power plant wind resource calculation result by utilizing the calculation result, the wind measurement data and the unit information of the wind turbine generator. According to the method disclosed by the invention, the result obtained by the mesoscale WRF mode is extracted and reconstructed, and the reconstruction result is used as the inflow boundary condition of the microscale CFD model, so that the accuracy and precision of wind resource calculation are improved.

Description

technical field [0001] The present application relates to the technical field of wind power generation, and more specifically, relates to a wind resource calculation method, device, equipment and computer-readable storage medium of a wind farm. Background technique [0002] As the core link of wind farm development, wind resource assessment and measurement play a very important role in the success or failure of wind farm benefits and wind farm investment. With the advent of wind power grid bidding or even grid parity, the investment benefits of wind power generation are gradually compressed, and the development of wind farms is at the break-even point. Therefore, it is becoming more and more important to improve the accuracy of wind resource calculation. [0003] At present, computational fluid dynamics (CFD) technology is used as the core to calculate wind resources in wind farms, and numerical simulation and calculation are often carried out with the help of micro-scale CF...
