“…The stability of the internal components of wind turbine generators significantly affects the power quality, and the generating voltage and frequency must be as stable as possible in order to produce high-quality power [8]. Hydraulic transmission can maintain the output at an almost constant voltage and frequency by continuously controlling the capacity of the hydraulic motor according to the variable wind speed conditions.…”

Featured Application: SimulationX is graphical-user-interface-based commercial software that is considerably useful for developing and analyzing a mechanical system as a single simulation environment because it can be easily applied in various research fields such as structural analysis, flow analysis, controllers, and dynamics.Abstract: Wind turbine generators are eco-friendly generators that produce electric energy using wind energy. In this study, wind turbine generator efficiency is examined using a powertrain combination and annual power generation prediction, by employing an analysis model. Performance testing was conducted in order to analyze the efficiency of a hydraulic pump and a motor, which are key components, and so as to verify the analysis model. The annual wind speed occurrence frequency for the expected installation areas was used to predict the annual power generation of the wind turbine generators. It was found that the parallel combination of the induction motors exhibited a higher efficiency when the wind speed was low and the serial combination showed higher efficiency when wind speed was high. The results of predicting the annual power generation considering the regional characteristics showed that the power generation was the highest when the hydraulic motors were designed in parallel and the induction motors were designed in series.

“…The main disadvantage of the downwind configuration is the tower shadow that can cause periodic loads. This periodic load may result in fatigue damage to the blades and may impose a ripple on the generated electrical power; however there is some smoothing effect in the power fluctuations if we consider OWTs as a wind farm [8,9]. These effects can be decreased by a teetering hub and an individual pitching mechanism while on the contrary these increase the complexity and the associated maintenance.…”

“…Finally, it is worth noting that in wind power plants a large number of high power converters are usually used, therefore each wind turbine unit output power provides a high level of harmonics. By applying an active filter solution output harmonics can be alleviated in order to accomplish with the required power quality standards [3][4].…”

Abstract.This paper presents a control design and implementation analysis of a three level grid connected converter to be deployed in large scale wind turbine applications, which main purpose is to obtain enhanced grid interaction by limiting its harmonic injection capability. The implementation of advanced power converter control in high power converters allows the proposed wind turbine system to provide active and reactive power supply while performing active filter functionalities for the 5th and 7th harmonic current components. Finally, the performance of the system is verified under several practical study cases by performing a laboratory analysis of the obtained results.
