  • H15

    The Britwind H15 is something special for a small windmill. It's a best in class machine, designed by the same team that developed the market leading Britwind R9000 wind turbine. And it's a turning point for the small wind industry.

    Like the R9000, the H15 has been has been engineered with robustness, high reliability and low maintenance in mind, and the only wearing parts are the rotor bearing, the yaw bearing and the anemometer. On top of that though, the H15 also has class leading performance to installed cost ratio – which means you'll be getting your money's worth and then some!

    There are two versions you can choose from; the Class II (as per IEC 61400-2) for the windiest sites, and the large rotor Class IV, which has exceptional performance at lower wind speeds. The Britwind H15 conforms to IEC 61400-2 international standard and has accreditation in the UK under MCS.

    Feature

     

    Benefit

     

    Direct drive generator with the following features:

    - High efficiency – especially at low wind speed
    - Ability to act as the brake: both bringing the turbine to rest, and keeping it ‘parked’ in the most challenging wind conditions (known as the 50 year wind)

    Low cost of energy

    No wearing parts or maintenance

    Patented electrical braking concept – generator is simply switched to a ‘coil pack’ - achieving near constant brake torque at all rotor speeds

     

    Effective, yet simple with no wearing parts

     

    Free yaw with tail vane

     

    No wearing parts and minimal maintenance requirements

     

    Fail safe electrical brake with two independent microprocessors, that triggers in the event of rotor over speed, high wind speed, high vibration or electrical fault

     

    Highly reliable brake with redundancy – unlikely to ever fail.

     

    Secondary ‘one-shot’ emergency backup brake for over speed protection. This pitches one blade to stop the turbine. Needs a maintenance visit to reset

     

    Simple, reliable emergency back-up without wearing parts

     

    Purpose built inverter with bi-directional control allowing the rotor to be motored up to speed in low wind speed conditions

     

    Optimising performance and contributing to the low cost of energy

     

    Remote monitoring via GPRS

     

    Intended to detect abnormal behaviour and apply the brake before deterioration can occur and to allow improved maintenance planning

     

    Tilt-down tower for installation, servicing and maintenance

     

    Safe and full access to the turbine with no working at height Health and Safety issues
