  • Analysis of the Steady state performance of doubly fed induction machines 
    Zhu Jianguo; Boardman Gerard; Ha Quang (Australian Power Engineering Committee, 2002)
    This paper discusses the steady state maximum and minimum torque outputs and the operation at unity power factor of the doubly fed twin stator induction machine and the doubly fed induction machine using equations with ...
  • Applications of NSW condition monitoring technologies in the electricity transmission industry 
    Jones Steven; Kingsmill Andrew; Zhu Jianguo (Australian Power Engineering Committee, 2002)
    In recent years a number of new devices and sensors have become available in the electricity industry that perform continuous, online monitoring of key parameters or indicators of the condition of high voltage plant. ...
  • Design of a 500W PEM fuel cell test system 
    Holland Brett; Zhu Jianguo (Australian Power Engineering Committee, 2002)
    This paper describes the design of a 500 W PEM fuel cell test system which can be used for both validating fuel cell models and for measuring the fuel cell model parameters. The software controllable operation and wide ...
  • Direct Torque control of permanent magnet Synchronous motor based on fuzzy logic 
    Zhu Jianguo; Sun Dan; He Yi (Australian Power Engineering Committee, 2002)
    In the conventional direct torque control (DTC) of a permanent magnet synchronous motor (PMSM), hysteresis controllers are employed to select the proper voltage vector resulting in large torque ripples, and the inverse ...
  • General Reference frame modelling of the doubly fed twin stator induction machine using space vector 
    Zhu Jianguo; Boardman Gerard; Ha Quang (Australian Power Engineering Committee, 2002)
    This paper discusses the modelling of the doubly fed twin stator induction machine in the general reference frame using space vectors based on the cascade connection of two wound rotor induction machines that have, in ...
  • Modelling and steady state performance analysis of brushless doubly fed twin stator induction generator 
    Zhu Jianguo; Basic Duro; Boardman Gerard (Australian Power Engineering Committee, 2002)
    This paper presents an improved steady-state model and performance study of a brush less doubly fed twin stator induction generator (BDFTSIG). The proposed steady-state model is modified to take into account magnetic ...
  • Modelling polymer electrolyte membrane fuel cell 
    Holland Brett; Balkin Andrew; Zhu Jianguo (Australian Power Engineering Committee, 2002)
    The Polymer Electrolyte Membrane (PEM) fuel cell model proposed incorporates both analytical and empirical techniques. The model is based on a comprehensive literature survey and comparative study of fuel cell modelling ...
