VAWT design must be robust, to meet climate change challenges
Our 5-blade, H-shape turbines are optimized for tough and varied environmental conditions across Australia and are ideally suited to turbulent wind conditions. Annual average wind conditions vary substantially from coastal to inland areas and are affected by many topological conditions. ATD Energy is focused on customers with a genuine commitment to effective climate change reduction and a commercial necessity to reduce their energy costs – not simply the means to generate income from dwindling Feed-In-Tariffs.
Industries depend on energy when they need it – not when it’s generated.
Wind resources are not uniform across an area, or a grid of say 5 square km. As well, different topologies and surrounding obstacles such as buildings, trees, and hilly terrain will impact wind flow. Our VAWTs combine five aerodynamically curved aerofoil blades connected to a centrally mounted permanent magnet generator. By adjusting the blade angle in real-time per rotation, the blade obtains the best angle at any azimuth, increasing the driving torque in both upwind and downwind positions. This means that each blade can supply and sustain power from any position using what is called ‘pitch angle regulation’.
Mounted high on a 12-metre pole, they require a low start-up torque, or a light gentle breeze to drive them and generate power. We currently provide these in 3kW, 5kW, and 10kW sizes to suit any environment from urban and rural, to industrial and commercial locations. High-end small-scale turbines are fast becoming a necessary addition to renewable energy systems.
Our turbines supplement solar energy limitations. Connected to battery storage systems, they provide a 24-hour energy resource.
