Reads turbine data from a TBL file.

Examples¶

A TBL file is a csv file with space as separator and two header lines. The followind lines denote wind speed, ct, P.

• first row will be ignored

• second row: H D ct-stand-still rated-power-in-MW

• further rows: ws ct P-in-kW

For example:

45 175.0 290.0 0.03 22.0 3.0 0.820 102.9 3.5 0.800 444.0 4.0 0.810 874.7 4.5 0.820 1418.7 5.0 0.820 2100.9 5.5 0.830 3021.2 6.0 0.830 3904.7 6.5 0.830 5061.7 7.0 0.810 6379.0
