Windflow turbine tested and rested
Windflow Technology’s prototype wind turbine at Gebbies Pass (near Christchurch) has been halted for minor repairs and
design improvement work.
“We’ve achieved a milestone of 120 hours of continuous operation through some strong and turbulent nor-west winds,” said
Windflow Chief Executive Officer Geoff Henderson. “We decided to shut down the machine when the pitch actuating tube
fractured. It’s a small, but important part of the turbine’s control mechanism and in hindsight it is obvious why this
happened. We’ll replace it with a new one that we have designed. We will also take this opportunity to improve the
cladding mounts and refine the control software before re-starting the turbine.”
The company will do the retrofit work in Christchurch and expects to have the turbine running again in couple of weeks.
“This is just normal prototyping stuff as we continue to refine the details and learn how well the machine performs in
gusty winds,” Mr Henderson said. “These modifications will be incorporated into the next turbines we build. Our next
objective is to achieve 240 hours continuous running without any faults.”
