1 KW WIND TURBINE SYSTEM CONSTRUCTION AND PERFORMANCE MONITORING

Project Supported by:

Renewable Nepal Programme

Collaborations:

Kathmandu University: (DOEEE)

Wind energy is comparatively less mature in Nepal compared to other alternative energy technologies like micro-hydro, biogas and solar. Due to lack of successful demonstration, inadequacy in awareness level-technical capacity-R&D facility, the development of this renewable energy sector is comparatively very slow. KAPEG has been working on developing small wind turbine system and facilitate off-grid communities having good wind potential.

The objectives of the project was to construct 1kW wind turbine system (Hugh Piggot 4.2m turbine designs) using locally available resources at Kathmandu. A 1kW turbine was constructed at KAPEG and later installed at location "Nagarkot".

The performance of the turbine was monitored using datalogger and sensors assembled at KAPEG lab. The data monitoring system stores the value of battery voltage, generator current, wind speed, wind direction and frequency in order to be able to plot power curve and efficiency curve.
