Problems solved by technology

This is a process involving the deep participation of multiple designers, especially in the development and design of new models, which requires high manpower and resource costs
In addition, since the wind turbine is a complex system, the designer adjusts the parameters of the controller model for a certain load index may cause unpredictable fluctuations in other load indexes, so it is difficult to obtain relatively optimal parameters conveniently

Abstract

The invention provides a method and a device for optimizing the load of a wind turbine generator set. The method comprises the steps: obtaining at least one control parameter of the wind turbine generator set, wherein the loads of multiple locations of the wind turbine generator set are affected by at least one control parameter; obtaining the load values of multiple locations of the wind turbinegenerator set corresponding to at least one control parameter; quantizing the load values of multiple locations into single evaluation values by using a predetermined evaluation model; judging whetherthe evaluation values meet the predetermined conditions; optimizing at least one control parameter based on the evaluation values by using a predetermined optimization algorithm when the evaluation values do not meet the predetermined conditions to update at least one control parameter and obtaining at least one control parameter again; and using the obtained at least one control parameter as thefinal control parameter when the evaluation values meet the predetermined conditions.

Description

technical field [0001] The present invention generally relates to the technical field of wind power generation, and more particularly relates to a method and device for optimizing the load of a wind power generating set. Background technique [0002] The design of wind turbines usually starts with the load calculation. For this purpose, it is necessary to establish a mathematical model of the wind turbine and determine the control strategy, and the adjustment of the parameters related to the control strategy will obviously affect the results of the load calculation. [0003] In the design stage, designers usually adjust the relevant parameters of the controller model by analyzing the operating points derived from the linearization data of the wind turbine model in the time domain and frequency domain based on past experience and understanding, or by The unit model performs simulations of various working conditions, and the statistical analysis of the simulation results is us...
