Static torque, no load, constant speed, and sinusoidal oscillation test data for a 10hp, 300rpm magnetically-geared generator prototype using either an adjustable load bank for a fixed resistance or an output power converter.

Project and generator specifications and initial prototype test data for flap-type wave energy converters (WEC)

This data is a result of an experimental campaign to characterize the hydrodynamics and performance of a laboratory-scale oscillating surge wave energy converter (OSWEC). The device was 85 cm wide, 1.4 meters tall, and 14 cm thick and was tested in the Sea Wave Environmental Lab (SWEL) wave tank at the National Renewable Energy Laboratory which is 2.5 meters wide with a water depth of 1.3 meters. The device included fifteen pressure sensors on the flap face, two 6-axis load cells at the hinge, an encoder to measure flap position, and a motor to emulate a PTO and absorb power. We provide a full summary of the device and experiments in the TEAMER Post-Access Report titled "Optimal control of an oscillating surge wave energy converter". This DropBox directory contains data from four types of experiments: 1. Buoyancy Tests - We measure the torque required to hold the flap at different angles to characterize buoyancy torque as a function of position. 2. Locked Flap (Excitation) Tests - We measure the torque on a locked flap subject to different wave parameters to extract the excitation torque coefficient. 3. Forced Oscillation (Radiation) Tests - We force the flap to oscillate at different periods and amplitudes to extract added inertia and radiation damping coefficients. 4. Control Tests - We subject the flap to different waves and use a linear damping controller to emulate a PTO and extract absorbed power and capture width ratio (CWR) as a function of wave and control parameters. This data set includes raw and processed time series data from the encoder and load cells, as well as calculated hydrodynamic and performance parameters from the tests. We include a README document as well as a spreadsheet with individual test details as a reference. Funding for this experimental campaign was provided by the TEAMER Program under RFTS 10 and was a collaboration between the University of Washington and the National Renewable Energy Laboratory.

In order to generate a public data set that can be used to validate Wave Energy Converter (WEC) numerical codes, such as WEC-Sim, Sandia National Laboratories led an experimental testing campaign of a 1:33 scale Floating Oscillating Surge Wave Energy Converter (FOSWEC) in the Directional Wave Basin at Oregon State University's Hinsdale Wave Research Laboratory. Testing was performed in two phases; Phase 1 testing was completed in November - December 2015, and Phase 2 testing was completed in May - June 2016. This experimental testing report details the selection and design of a FOSWEC, experimental setup and tests, and overview of the resulting dataset from Phase 1 and Phase 2 testing.

The TidGen Power System generates emission-free electricity from tidal currents and connects directly into existing grids using smart grid technology. The power system consists of three major subsystems: shore-side power electronics, mooring system, and turbine generator unit (TGU) device. This submission contains supporting CFD files, case files and geometry for the Advanced TidGen. TSR = Tip speed ratio Cp = Power coefficient Cl = Lift coefficient Cd = Drag coefficient

Input data and heave results (unsteady RANS-VOF overset simulations performed in Star-CCM+) for a float with an ellipsoid geometry. Five extreme sea states were considered, as detailed in the conference paper "Application of the Most Likely Extreme Response Method for Wave Energy Converters" by Quon et al. (see resource below). These sea states were extrapolated from conditions near Humboldt Bay, California. Focused waves were generated using the MLER module of the Wave Design Response Toolbox (WDRT) and specified at the inlet boundary conditions. The device was constrained to heave only and a PTO was not modeled.
