Streszczenie

Kluczową kwestią przy analizie efektywności turbin wiatrowych jest zjawisko pełzania momentu siły zarówno pod obciążeniem, jak i bez obciążenia. Zjawisko to ma istotny wpływ na poprawne działanie przetworników momentu siły, dlatego wymaga zastosowania odpowiednich algorytmów do analizy danych pomiarowych. Metoda najmniejszych kwadratów jest odpowiednia do takiej analizy. Zastosowano regresję liniową do zbadania samego trendu pełzania, a nieliniowa krzywa wielomianowa trzeciego stopnia pozwoliła na jego wizualizację.

Słowa kluczowe

Analysis of Creep in Torque Transducers for Wind Turbine

Abstract

A crucial aspect to consider when assessing the effectiveness of wind turbines is the phenomenon of torque creep, both under load and without load. This phenomenon significantly affects the proper functioning of torque transducers, thus necessitating the utilization of suitable algorithms for analysing measurement data. The least squares method is well-suited for this type of analysis. Linear regression was employed to study the creep trend, while a third-degree non-linear polynomial curve enabled a more precise visualization of creep, yielding valuable insights.
