Development and Analysis of a Novel Vertical Axis Wind Turbine - Paul Cooper and Oliver Kennedy - This paper describes the development of a novel vertical axis wind turbine used for teaching and research purposes. The device is designed to operate at low tip speed ratios and features blades that are symmetric about the mid-chord plane. The blades are actively pitched by means of a mechanical system so that the chord of each blade rotates by 180º for every revolution of the main rotor. One of the attractions of the device is that it is self-starting and produces relatively high torque. A multiple streamtube analysis of the device has been developed and numerical predictions for the performance of the device are presented. Commissioning and field tests of a prototype are described and some preliminary performance results are presented and discussed - From the University of Wollongong.

Effects of Complex Wind Regimes on Turbine Performance - Elisabeth Rareshide, Andrew Tindal1, Clint Johnson, AnneMarie Graves, Erin Simpson, James Bleeg, Tracey Harris and Danny Schoborg - Wind turbine power performance for the annual energy production calculations of wind farms has traditionally been modeled assuming a set of simple and average input meteorological conditions. Turbine power curve tests are also performed with this assumption, based on criteria defined in the IEC 61400-12-1 [1] standard. While this approach has proven to be adequate for the wind power industry for several years, the increasing size of wind turbines—coupled with an improved awareness of the wind flow variation throughout the boundary layer—has generated concern that the effects of complex meteorological conditions on turbine power performance are not well understood - from Garrad Hassan.
