- Scope
- The wind farm benchmarking evaluation index system uses a total of 7 indicators in five categories as basic statistical indicators, all calculated using the single machine method. The wind farm index is the average of all single machine indicators in the wind farm. The calculation of single machine indicators is based on the two data of wind speed and active power of the wind turbine. The wind turbine is divided into five states: data interruption, normal operation, limited load operation, shutdown, and standby. The duration, theoretical power generation, and actual power of each state are calculated. Power generation, of which the theoretical power generation refers to the "Wind Farm Standard Energy Availability Evaluation Procedure". After the SCADA wind speed is corrected to the actual wind speed in front of the hub, twin power curves are used for unified calculation to ensure the status division of the wind turbine and the lateral alignment of the wind farm. The target is objective, fair and impartial.
