A novel flicker detection method for vertical axis wind turbine using two‐dimensional discrete wavelet transform

Abstract: Background Pattern recognition applications have increased dramatically over the past four decades. In power system, pattern recognition can be used in fields such as power quality. One of the important power quality aspects is flicker, which is caused by torque fluctuations in wind turbines. Aims In this paper, the various mechanical faults including single and double faults that cause flicker in vertical axis wind turbines (VAWTs) are modeled; then flicker caused by single and double faults are analyzed. The… Show more

“…Other scenarios such as LLG fault and switching a large capacitor are added to the mentioned harmonic sources. It is notable that wind turbines alone can be the cause of generating flicker and harmonic [34,40]. Combined PQDs were introduced in classes 11 to 15.…”

“…In the modern power systems, some events in diesel-engine driven generators such as misfiring in cylinders, and gearbox tooth crashing lead to generate flicker [33]. Also, some events in wind turbines such as tower shadow, wind shear, turbine blade break down, and blade pitching errors lead to generate flicker in the modern power systems [34]. To identify different combined PQDs in the modern power systems, a new method is presented in this paper.…”

“…There have been several studies on flicker source tracing, but they are not based on IEC 61000‐4‐15 23‐28 . Axelberg et al 29,30 proposed an analytical theory to detect the direction of the flicker source (FS) with respect to the monitoring points based on IEC 61000‐4‐15.…”
