AWEA 2012 Show Recap

Despite comments from many attendees saying booth traffic was slow, I think AWEA’s Windpower 2012 was a success. I even have the blisters to prove it. AWEA hosted the show in Atlanta, a major manufacturing hub, and consisted of two huge halls with well over 1,000 exhibitors. The “slow” traffic can be attributed to the state

Wind Reliability: Maintenance-free hydraulic accumulators

Wind turbine pitch, yaw, and brake systems use either electric or hydraulic actuation. The hydraulic systems use high-pressure, gas-charged hydraulic accumulators. Typically, either a bladder or a piston accumulator is used. Maintenance-free, metal bellows accumulators can offer an advantage in these applications. A piston accumulator consists of a cylindrical metal body with end caps and

New Wind App: Wind Turbine Cost Model

After previously launching Wind Expert, Michael Blaize is at it again with his new Wind Turbine Cost Model. The app brings a detailed and advanced model to evaluate the cost of any horizontal wind turbines above 750kW. Based on the validated NREL cost model, Wind expert Wind Turbine Cost Model gives an in-depth understanding of
