Problems solved by technology

[0005] The existing simulation device does not consider the influence of the wind shear tower shadow effect on the operation of the wind turbine. It is simulated with a real direct-drive wind turbine, which is large in size and expensive, and has relatively high requirements for the experimental site.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, in particular to a wind power generation simulation platform. Background technique [0002] Existing permanent magnet wind turbine simulation platforms include: [0003] The motor drives the wind turbine through the transmission to simulate the wind turbine system; and, [0004] The simulation of the wind power generation system can be realized by building the model of the wind power generation system through the software. [0005] The existing simulation device does not consider the impact of the wind shear tower shadow effect on the operation of the wind turbine. It is simulated with a real direct-drive wind turbine, which is large in size and expensive, and has relatively high requirements for the experimental site. Contents of the invention [0006] The invention provides a wind power generation simulation platform. [0007] The technical solution of the present invention i...
