Rapid evaluation and optimization method for wind field adaptability of wind generating set based on sector distribution

Abstract

The invention discloses a rapid evaluation and optimization method for the wind field adaptability of a wind generating set based on sector distribution. By building a wind resource parameter combination mode, sector control strategies are built, a wind generation set operation information database is built, interpolation calculation of the fatigue load and the generation power of the wind generation set is conducted, and the wind field adaptability is rapidly evaluated through an optimization algorithm. According to the characteristic that sector distribution of wind resource parameters is different, the corresponding sector control strategies are formulated and used as the input conditions for simulation of the wind generating set; and the wind generating set operation information database is built in a simulating mode in advance, and the optimization algorithm is adopted, so that rapid evaluation and optimization of the loads and the generating capacities of all machines in a wind field are achieved. The fatigue loads and the annual generating capacities of the machines in the wind field at the early design stage can be reasonably predicted, the design period is greatly shortened, the development cost of the wind field is saved, and fine design of the wind field is achieved.

Description

technical field [0001] The invention relates to a fast assessment and optimization method for wind field adaptability of wind turbines based on sector distribution. Background technique [0002] With the development of wind power generation, my country's onshore wind power is developing in the direction of distributed wind power generation. For the target wind farm to be built, it is necessary to conduct a wind field adaptability assessment on the wind turbines to ensure the safety and economic benefits of the wind turbines, and the main content of the wind field adaptability assessment is the load evaluation and power generation evaluation of the wind turbines. [0003] At present, more and more wind turbines are installed in mountainous and hilly areas, resulting in very complicated wind resources for wind turbines. At the same time, in order to obtain higher annual power generation and economic benefits, wind turbines are moving towards longer blades and The direction of...
