Title:
CLEANING METHOD AND SYSTEM BASED ON OPERATION DATA OF WIND TURBINE GENERATOR SET
Document Type and Number:
WIPO Patent Application WO/2020/181786
Kind Code:
A1
Abstract:
A cleaning method and system based on operation data of a wind turbine generator set. The method comprises the following steps: obtaining the current operation data of a wind turbine generator set (S1); after normalizing the current operation data of the wind turbine generator set, calculating a distance from measured data to each pre-built wind turbine generator set theoretical operation curve in a wind turbine generator set theoretical operation curve model, and using the distance as a data deviation degree (S2); performing data cleaning on the basis of the data deviation degree and a data deviation degree threshold (S3), wherein the wind turbine generator set theoretical operation curve model is built by using behavioral parameters of the wind turbine generator set as parameters of the wind turbine generator set theoretical operation curve.
