Zusammenfassung |

[EN] There is described a method of determining a source parameter value (Uv,WEA, Iv,WEA) and an impedance parameter value (Zv,WEA) for an electrical model (1, 2) of a wind turbine generator, wherein the electrical model is representative of a selected harmonic occurring during operation of the wind turbine generator. The method comprises obtaining (310) a set of measured voltage values (Uv,NAP) and a set of measured current values (Iv,NAP) corresponding to the selected harmonic, calculating (315) an initial source parameter value (Uv,WEA,0) and an initial impedance parameter value (Zv,WEA,0) based on the set of measured voltage values and the set of measured current values, calculating (330) a respective fitting index (r) for each of a plurality of candidate combinations of respective candidate source parameter values and candidate impedance parameter values, wherein each candidate source parameter value is obtained as a multiple of the initial source parameter value divided by a first predetermined number and each candidate impedance parameter value is obtained as a multiple of the initial source parameter value divided by a second predetermined number, selecting a subset of the candidate combinations for which the corresponding fitting index is maximal, and determining (360) the source parameter value (Uv,WEA,opt) and the impedance parameter value (Zv,WEA,opt) based on the selected subset of candidate combinations. |
