Wind turbines - Measurement and assessment of power quality characteristics of grid connected wind turbines has-digital Test methods – Tone valueBS 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
