| Wind turbine power characteristics,wind resources applicability,and wind turbine reliability are the important indicators of wind turbine.In a wind farm,these indicators will directly influence the wind turbine generating capacity.In this paper,the wind turbine performance was evaluated through analysis the data which are stored in wind turbine computer such as wind speed,power,downtime status,fault conditions,and so on.We also compare the actual wind turbine power curve with the standard power curve, and analyze the change of the power curve with the length increasc of the wind turbine operation term.Generating capacity,availability,and wind farms design post-evaluation are studied after the above data analysis.We put forward an evaluation method which is utilizable,simple,and easy to facilitate for a long-term.The wind turbine aging performance causing from long term running will lead to that the actual power is less than the reference power.Take the technical measures of pitch adjusting,and blade washing or repairing can impove the wind turbine power performance,and increase its generating capacity. |
