RPM sensor

Monitoring the rotational speed of the wind turbine blades can help with power performance measurements. This post shows various techniques to measure the rotational speed of a ‘wild AC’ output small wind turbine. In this system, the wild AC is rectified into DC and either delivered to a battery or to a grid-connected inverter. The … more

Low-Cost Wind Datalogger

Wind speeds are very site-dependant – with topology, ground roughness and other factors affecting the local wind speed. Knowing the wind speed and frequency of the wind speed at a particular location allows us to make a more accurate resource assessment. An accurate resource assessment is required for ensuring the wind turbines are sited correctly … more

V3 wind turbine

Renewable Energy Innovation was asked to help install a small (700W) hand-built wind turbine on Shabel Farm, an organic dairy farm in Oberner Stollenhof, Nr. Rechburg, Schwabel Gmund, Germany.The wind turbine was based upon Hugh Piggotts design and had been built by Matthias Kössler, after he had been on one of V3 Power’s wind turbine … more

Fibreglass wind turbine blades

This was a practical guide produced while for SIBAT, an NGO working in the Philippines, on the construction of fibre-glass wind turbine blades for a 1kW wind turbine. This work was part of a one-year placement in the Philippines funded by Engineers Without Borders UK. … more
