Self - Excitation and Voltage Control of an Induction Generator in an Independent Wind Energy Conversion System

This paper proposes an excitation system and voltage control for a Squirrel Cage Induction Generator in an independent wind energy conversion system. Energy is considered to be very promising alternative for power generation because of its tremendous environment, social, and economic benefits. Of all wind power technologies, the variable speed systems employing the Squirrel Cage Induction Gener...

A Novel Voltage and Frequency Control Scheme for a Wind Turbine Driven Isolated Asynchronous Generator

This paper deals with the control of voltage and frequency of a wind turbine driven isolated asynchronous generator. The controller consists of an IGBT (Insulated Gate Bipolar Junction Transistor) based 3-leg voltage source converter and a battery at its DC link. The controller is having bidirectional flow capability of active and reactive powers by which it controls the system voltage and freq...

Wind turbine modelling and identification for control system applications

This paper deals with a model of a 3-bladed wind turbine and its identification. The linear, time-invariant state-space model has been developed at Fraunhofer IWES mainly for control engineering applications. Its parameters are obtained from an operational modal analysis carried out on a commercial 5MW turbine. The parameterised model is validated by comparison of estimated time series and meas...

A Wind Turbine Benchmark for Hybrid System Analysis & Design

Recent years have witnessed an enormous growth of interest in dynamic systems that are characterised by a mixture of both continuous and discrete dynamics, commonly referred to as hybrid or switching systems. Nevertheless, there is a notable lack of suitable benchmark problems on which to assess and compare competing analysis and design methods. The present paper provides a collection of detail...
