The dataset file contains data regarding the electrical and mechanical operational actual quantities and parameters obtained and recorded by the internal inverter controller of a Skystream 3.7 small wind turbine (SWT) installed on the roof of the High Voltage Laboratory at the Institute of Energy and Environment (IEE) of the University of Sao Paulo (USP), Brazil, recorded from 2017 to 2022. The main electrical parameters are the energy, voltages, and currents in the connection grid point and power frequency. Mechanical information can be retrieved, such as the rotation and the wind speed. The temperature, measured in some location points to the nacelle and inverter, is also recorded. Several other parameters concerning the SWT inverter operation, such as the dc voltages on its internal bus, alarms, and flags, are also presented. The files in the dataset are named as "data_swt_iee_usp_YYYY.csv" where YYYY is the referring year. In the files, the semicolon symbol (;) is used as a column separator, while the dot symbol (.) represents the decimal separator. The first row of the CSV file corresponds to the header row to help identify data as described in the file "data_description.txt". Sampling rate one record per minute. The first line on each year-based file represents the header table description of the data columns. The complete and detailed information about the installation, localization,and analysis is in the article published at: https://doi.org/10.3390/wind2040037 LIST OS STATUS CODES - Skystream 3.7 Premise: Binary logic, where each status is represented by a specific bit within an integer value. Numeric Code Turbine Status Grid Status System Status 0 Normal. Run with energy generation Normal (No faults detected) Normal (System operating without errors) 1 Low Windspeed L1 Low Voltage HS Backoff 2 Braking L1 High Voltage SIP TX Too Long 4 Overspeed L2 Low Voltage Improper Reset 8 No Stall (Normal Operation) L2 High Voltage Battery Timeout 16 High Wind Test Offset Limit Drive Off 32 Anemometer mode Phase Error Slave Shutdown 64 Ramp Frequency Low Temp Shutdown 128 TSR Incr Frequency High High Temp 256 Power High DPLL Unlock Run (Normal Operation) 512 TSR Limit Grid Disconnect Disabled 1024 Quiet Anti-Islanding Waiting 2048 Incr Delay Temp Backoff 4096 RPM Control Bad Setpoints 8192 Vin High Bad CRC These codes can represent cumulative causes, adding values when multiple causes occur. EXAMPLES: Turbine status = 0 => Generating/Run Turbine status = 1 => Low Windspeed Turbine status = 3 => Low Windspeed and Braking Turbine status = 9 => Low Windspeed and No Stall Turbine status = 33 => Anemometer mode and Low Windspeed System status = 1024 => Waiting System status = 256 => Run Grid status = 512 => Grid Disconect
