Scope

Scope: This standard applies to grid-connected wind power farms; Main technical content: The benchmarking evaluation index system for wind power farms uses five categories and seven indicators as basic statistical indicators, all of which are calculated by the single-machine method. The wind power farm indicators are the average values of all single-machine indicators in the wind power farm. The single-machine indicators are calculated based on two data of wind speed and active power of the wind turbines, which are divided into five states: data interruption, normal operation, load-limiting operation, shutdown, and standby. The duration, theoretical power generation, and actual power generation of each state are statistically analyzed. Among them, the theoretical power generation refers to the provisions of the "Evaluation Procedures for Standard Energy Availability of Wind Power Farms". After correcting the SCADA wind speed to the actual wind speed in front of the hub, the twin power curves are used for calculation to ensure the objective, fair, and just evaluation of the wind turbine states and the horizontal benchmarking of wind power farms.
