Abstract

The invention provides a wind power generator set transmission chain optimization method and device. The wind power generator set transmission chain optimization method comprises the steps that an evaluation factor set of transmission chain design schemes is confirmed; separate evaluation is performed on all factors in the evaluation factor set according to a single-factor evaluation matrix obtained from a fuzzy mapping set; and fuzzy synthetic decision is performed on all the transmission chain design schemes according to a given weight matrix and separate evaluation results of all the factors, and the optimal transmission chain design scheme is obtained. By means of the wind power generator set transmission chain optimization method and device provided by the invention, comprehensive optimization on the wind power generator set transmission chain design can be realized.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method and device for optimizing a transmission chain of a wind power generating set. Background technique [0002] The transmission chain is the main actuator of the wind turbine. Doubly-fed wind turbine technology is mature. Its transmission chain can basically be divided into components such as wind wheel, main shaft, speed-up gearbox, generator and so on. The transmission chain does not include the wind wheel part in the patent of the present invention. The transmission chain structure of the wind turbine is complex, and there are many important components, which directly affect the stability, safety and economy of the unit operation. Its design optimization process is a complex multi-objective optimization problem. The method of using fuzzy mathematics to model the target that needs to be evaluated, and then comprehensively evaluate the factors that affec...
