Operation SCADA Dataset of an Urban Small Wind Turbine in São Paulo, Brazil
- 1. University of São Paulo (USP), Institute of Energy and Environment (IEE), Center for Analysis, Planning and Energy Resources Development (CPLEN)
Description
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
