Big data combined complex terrain wind electric field design platform and method

Abstract

The invention discloses a big data combined complex terrain wind electric field design platform and method. The big data combined complex terrain wind electric field design platform comprises a simulation platform, a big data workstation and an optimization layout platform; the simulation platform comprises a meso-scale numerical simulation module, a down-scale wind resource model module, a terrain considered wind field flowing model module and a wake stream model module which are connected successively; the data workstation comprises a wind electric field big data platform and a data analysis model module; and the optimization layout platform comprises a wind electric field generating capacity calculation model module, and a wind electric field optimization layout calculation model module. According to the big data combined complex terrain wind electric field design platform and method disclosed by the invention, a generating capacity model is corrected based on the big data workstation; operation modes and geographical factors which affect fan equipment are embodied in generating capacity calculation to reduce a fatigue loading rate of a fan; and thus, the maintenance cost is reduced, and the fan arrangement is optimized reasonably.

Description

technical field [0001] The invention belongs to the technical field of wind power, and in particular relates to a complex-terrain wind farm design platform and method combined with big data. Background technique [0002] Early wind farms were mostly built in places with rich wind energy resources and relatively flat terrain, but as wind farms became larger and more numerous, wind farms began to be built in areas with complex terrain. At present, the key technologies for the optimal design of complex wind farms in my country (including macro site selection, wind measurement, micro site selection, etc.) are still relatively weak, and the design and control of wind farms based on foreign experience cannot meet the needs of my country's special terrain, wind conditions and national conditions From the perspective of the completed wind power projects, there is still a large room for optimization in the design and control of wind farms, especially for wind farms in complex areas, m...

Problems solved by technology

In addition, due to the interference of many practical factors during the operation of the wind turbine, the power generated by the wind turbine calculated by the mechanism is usually different from the actual one.

The model correction technology based on big data is a research hotspot in recent years, but it has not been used in the design optimization of wind farms
