Portrait modeling and evaluation method of wind turbine power generation performance based on operation data
摘要
Abstract
In view of the declining performance of wind turbines,it is of great significance to construct a set of objective,comprehensive and accurate dynamic modeling methods of wind turbine power generation performance for the identification of equipment operating conditions,operation and maintenance,and assessment of grid-connected performance.This paper establishes a framework for modeling the power generation performance of wind turbines,and establishes a hierarchical"input-output"index system for wind turbine power generation performance based on three types of criteria,namely,wind resource characteristics,output characteristics and operation characteristics;and utilizes the fuzzy hierarchical clustering analysis method and fusion data characterization method to construct a subjective and objective combination of multi-indicator empowerment scheme,and constructs an absolute performance evaluation model for the power generation performance of the turbine.The absolute performance evaluation model of power generation performance is constructed;the relative power generation performance scale evaluation model of wind turbine is constructed by using the data inclusion analysis method to characterize the operation efficiency of the turbine;the information entropy and temporal degree are introduced to calculate the dynamic time-sequence weighting matrix,so as to realize the dynamic evaluation of absolute and relative performance of wind turbine,and to analyze the operation condition and evolution trend;the operation data of wind turbine in a wind farm verify the effectiveness and reasonableness of the proposed system.A case study of wind turbine operation data from a wind farm verifies the effectiveness and rationality of the proposed system.关键词
