WP6: Optimal Turbine Arrangement For Power Output and Quality
Objectives: Develop computational models to outline what the effect of varying turbine arrangements have on the power electronics and ultimately, the power quality and system efficiency.
Description of work:
Examine optimal turbine arrangements for efficiency and power quality using ORPC cross flow turbine designs. Major turbine characteristics that will be examined include: number of foils, foil twist angle, and the addition of turbine fairings. Power electronics will be standard COTS designs but will need sophisticated control algorithms to take into account torque and electrical current transients throughout a turbine’s rotation caused by the turbine foils reaching peak lift forces. These effects can introduce variance to the power output which can result in the output power not being grid worthy. This work package will develop torque vs. time curves for a range of different turbine arrangements which will be an input to the controls work package. The specific tasks undertaken as part of this work package are as follows:
Task 6.1: Outline the different turbine arrangements to be studied.
Associated deliverable: D6.1, Turbine arrangement drawing presentation. Due month 6. Confidential.
Task 6.2: CFD analysis for each turbine arrangement to output lift and drag forces for each option.
Task 6.3: Determine from CFD results what arrangement results in optimal power and energy outputs.
Associated deliverable: D6.2, CFD report and presentation on results. Due month 12. Confidential.
Task 6.4: Determine from CFD results how the turbine output will relate to electrical output.
