BS EN 61400-21:2008 Wind turbines. Measurement and assessment of power quality characteristics of grid connected wind turbines BS EN 61400-21 is the European standard for testing of wind turbines, though it contains information that may also be useful for testing of wind farms. BS EN 61400-21 of IEC 61400 includes:

Definition and specification of the quantities to be determined for characterizing the power quality of a grid connected wind turbine Measurement procedures for quantifying the characteristics Procedures for assessing compliance with power quality requirements, including estimation of the power quality expected from the wind turbine type when deployed at a specific site, possibly in groups.
