主 题:Wind turbine(WT) pitch system fuzzy comprehensive evaluation state evaluation
摘 要:To ensure wind turbine(WT)safe operations and improve the utilization rate of wind energy,effective evaluation of the operation state of the pitch system is ***,a new method was proposed to evaluate the operation state of the pitch system of WT based on fuzzy comprehensive ***,based on SCADA data,the working state of the pitch system under rated power state and power state of WT were ***,through the analysis of characteristic parameters and physical mechanism of the pitch system,the consistency principle of characteristic parameters,the stability principle of power under rated state,and the stability principle of blade angle underpowered state were ***,based on the aforementioned principles,the evaluation indexes were established,and the fuzzy comprehensive evaluation method was used to establish the operation state evaluation model of the pitch system under rated power state and under power state of the ***,an example was provided to verify the effectiveness of the *** evaluation model established in this study can be used as a technical reference for the online monitoring of WT pitch systems to ensure the safe and stable operation of WTs.
