Abstract

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.

Performance of Axial Generator for a Small Vertical Axis Wind Turbine

“…( 3 Individual small wind turbines can be used to generate electricity on a small scale [4]. As the wind turbine generators exhibited a significant difference in power generation, depending on the installation area and the wind occurrence frequency [31]. The small-scale applications of wind turbines in the long run with the development of generator technology, and the utilization of wind energy are still promising [32].…”
