Dynamic Modelling and Simulation of a Planetary Speed Increaser

Abstract

Many applications of wind turbines or hydro power plants include speed increasers meant to better harmonize the high input speed requirement of the electric generator with the typically low output speed of the converting turbine. This paper deals with a new variant of a planetary speed increaser used in wind or hydro turbines and presents some relevant aspects of the kinematic and dynamic modeling of the proposed planetary transmission. Based on a numerical example of a wind rotor - planetary speed increaser - DC electric generator, the dynamic response of this energy converting system is obtained by using the MATLAB Simulink software.
