DESIGN

• How does the LES6000 regulate its speed? The LES6000 knows how fast the turbine blades are spinning. If the blades momentarily attempt to spin faster than the maximum rpm due to gusting winds, then a brake load is deployed to slow the blades down. If the wind speed has increased beyond the level for generating maximum power, then the turbine points itself out of the wind so that not as much of the wind’s energy is harvested.
• Why doesn’t the LES6000 have a tail? The LES6000 employs large wind turbine technology to sense how fast the wind is blowing and from what direction. Knowing where the wind is coming from, the LES6000 uses an electric gear motor to move the turbine nacelle around the tower, pointing the blades either into or out of the wind as required.
• Why are there 3 blades on the LES6000? 3 is the minimum number of blades which gives the most stable and balanced mechanical arrangement. 2 blades can set cause the tower to oscillate at certain wind speeds.
• Can I monitor the output of the LES6000?. A kilowatt hour meter is mounted on the control panel to record the amount of energy the system has produced.
• What measures have been take to make the LES6000’s controls secure from theft, vandalism, etc? The LES6000’s control equipment is housed within a steel enclosure which incorporates a 3 point locking mechanism and a key lock.
• How safe is the LES6000? All of the LES6000’s systems are designed to fail safe. If the grid fails, or the wind speed increases to severe gale force or the turbine over speeds, the system shuts down in a controlled manner and parks itself. Additionally, the system and its components have been thoroughly tested in both laboratory and field conditions.
