The kite is programmed to fly in a pre defined direction, similar to the path that the tip of a wind turbine blade would make. The flight speed is high – over 100mph in 20mph winds.
Strong aerodynamic lifting forces are produced by the wing of the kite, and exerted against its network of bridles.
The tension causes a 100-200m line to be spooled out from a drum on the ground, which is connected to a generator – thus creating electricity.
The first kite must now retract to its starting position, consuming the minimum amount of energy.
We change the pitch of the wing, as this will minimise aerodynamic resistance, and the kite exits its generating flight pattern, gliding back towards the starting point.
Line tension is reduced by a factor of 10 or more, resulting in a net energy gain during the cycle.
The KPS cycle has two kites flying in the same airspace at any given time, so that while one is generating power, the other can be retracted.
Energy production is therefore continuous, and the alternator is kept rotating at optimal speed.
WE USE TWIN KITES: they share a common foundation and one generator.
WE CAN EASILY MAINTAIN OUR SYSTEMS: all components are serviced at an accessible height.
WE USE A SPECIALIST MATERIAL: this helps to minimise drag and maximise yield.
WE HAVE CONTROL: we can programme the kites to fly high above the ground.
WE DON’T NEED THE GRID: our technology is grid compliant, but can also operate off-grid.
WE USE A UNIQUE WINCH DESIGN: this optimises the entire system.
A significant problem that conventional wind energy faces is access for maintenance. At KPS, we have ensured that planned operations and repairs can be swiftly managed.
This means that the maintenance can be carried out in remote locations – whether it’s an onshore or offshore problem.
