{"@type": "dcat:Dataset", "accessLevel": "public", "bureauCode": ["019:20"], "contactPoint": {"@type": "vcard:Contact", "fn": "Olivia Vitale", "hasEmail": "mailto:ov35@cornell.edu"}, "dataQuality": true, "description": "This dataset was generated during the Heterogeneous Wave Energy Converter (HetWECs) experimental campaign conducted at the O.H. Hinsdale Direction Wave Basin at Oregon State University.  Experiments include system identification, hydrodynamics, and power take-off (PTO) tests. The experiments feature 4- and 5-body heterogenous WEC arrays consisting of both oscillating surge WECs and heaving point absorbers. Data was collected using Qualysis motion capture of the device motion, resistive wave gauges to capture wave height data at 20 locations throughout the basin, S-shaped load cells to measure wave excitation force and radiation force, and a Vesc 6 75 to measure motor current, motor RPMs, and FOC current. The submission includes post-processing MATLAB code is to support data handling and figure generation as well as test matrices detailing the sea state conditions for each experimental run.\n\nThe code is structured as follows:\ndata_and_code: overarching folder containing all raw data and post processing codes\n- PostProcessing_codes: folder containing 3 post processing codes which also stores the processed data\n1. primary_postpro: cleans and analyzes raw data from experiments based on user inputs.\n2. secondary_postpro: codes to create plots from the cleaned data\n3. processed_data: folder that stores data once it is cleaned with primary_postpro scripts. secondary_postpro pulls data from this folder.\n- Force_Sensor_Data: raw data from the S-shaped load cells attached to the devices during fixed wave excitation and forced oscillation testing.\n- qualysis: raw data from Qualysis motion capture DAQ for every trial. .QTM files have been removed for brevity and only .mat files remain. .QTM files available upon request.\n- Vesc_Data: raw data from on-board Vedder Electronic Speed Controller (Vesc) tracking motor angular velocity and current as well as input voltage. Applies to forced oscillation and PTO engaged tests.\n- wave_gauges: raw data from resistive and optical wave gauges for every trial. \n- README: contains \"data_and_code\" structure and additional notes/instruction on data and code use\n\nPre-processed data is provided to reproduce the figures in the Post Access Report (PAR). Pre-processing will be required to analyze data not explicitly plotted in the PAR. \n\nTo correlate dates and trial numbers to a specific test, reference the Test Matrices available in the MHKDR submission. Each test is labeled with a date and trial number.\n\nAll scripts are run through MATLAB. Though unfortunately MATLAB is not open-source, much of our data was output as .mat files (i.e., Qualysis and the wave gauges). Therefore, MATLAB was chosen as the data analysis software.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://mhkdr.openei.org/files/637/Test%20Matrix%20Hom4b%20%281%29.xlsx", "description": "This test matrix describes the sea state conditions for each trial run on the homogeneous 4b configurations.
