Dataset Title: Operation SCADA Data of an Urban Small Wind Turbine in São Paulo, Brazil

Doi:10.5281/zenodo.7348454

1 record per minute.

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 line on each year-based file represents the header table description of the data columns, as presented below.

Listed below is the meaning of each column in the data file:
