Abstract

The invention provides a wind generating set limit load data processing method and system. The wind generating set limit load data processing method comprises the steps of acquiring multiple sets of load time sequence data output by a wind generating set model within a target time range; for each set of load time series data, traversing each limit load data in the set of load time sequence data according to a time sequence, determining the change trend of each limit load data relative to the previous limit load data, and determining the previous limit load data as inflection point data when the change trends corresponding to two adjacent limit load data in the time sequence are different; sequentially connecting the initial limit load data and the inflection point data in each set of loadtime series data to generate a corresponding load curve; and displaying at least one load curve. The inflection point data determined through the method is more accurate and not prone to distortion, the drawn load curve can better reflect the overall change trend of the load time series data, and the requirement for limit load analysis is better met.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, the present application relates to a method and system for processing limit load data of a wind power generating set. Background technique [0002] Load calculations are the first key elements of wind turbine development and site-specific evaluation of the wind turbine. Through the load calculation, the performance and bearing level of the wind turbine can be determined, which is the premise input for the analysis and design of the wind turbine components. [0003] In the prior art, the load engineer needs to separately simulate the ultimate load of each component of the wind turbine under specific working conditions. Under the working conditions specified in the IEC standard, the fan components and their bearing levels that load engineers are concerned about include but are not limited to: (1) main bearing: ultimate load at the hub center; 15 degree ultimat...
