About the Wind Turbine

The H15 Class IV wind turbine was erected at RAL in February 2018, and commissioned on the 22nd February. . It is a modern horizontal-axis up-wind machine with a tower height of 18m and a 3-bladed rotor with a 13.1m diameter, and has a rated power of 12kW. The blades are fixed pitch and the rotor operates at variable speed, optimising energy production at low wind speeds. Therefore it is suitable for supporting research projects at RAL that require electricity generation from a renewable energy source.

The power in the wind increases rapidly with increasing wind speed. A power curve is generally used to characterise wind turbine performance, with significant points on the curve at the cut-in wind speed (around 3 - 4 m/s, when the wind turbine starts to generate), the rated wind speed (about 12 m/s above which the output power is regulated to the rated power), and the cut-out wind speed (about 14 m/s when the wind turbine starts to be shut down for safety and to avoid excessive stress).

The H15 wind turbine was manufactured and installed on the RAL site by Britwind: http://www.britwind.co.uk/
