Lean management of wind farms is crucial for enhancing economic efficiency

with accurate quantification of power generation losses and analysis of their causes being a core aspect. Based on the 10-minute SCADA data of Turbine No. 23 in the K Wind Farm in January 2016

this study proposes a complete quantitative analysis method for the power generation losses in wind turbines. The relationships among theoretical power generation

actual power generation

and power loss of the wind turbine during January are analyzed. The feasibility of quantifying power loss electricity based on 10-minute SCADA data is verified

providing data support and a decision-making basis for wind farms to optimize maintenance strategies

improving equipment availability

and enhancing coordinate operation of the power grid.
