This chapter shows the ways of optimising a medium power wind power electromechanical system, generating anything up to several tens of kilowatt electric power. The optimisation criteria are based on the cost of the electromechanical generator associated with a power electronic converter; on the power efficiency; and also on a fundamental parameter, often neglected in smaller installations, whi...

hydropower plant and especially micro-hydropower plant is an available, reliable and economical energy source. micro-hydropower plant is one of the most environment-friendly technology, use and development of which leads to reduction of energy consumption sporadically and worldwide. along with the growth of these power plants, the issues related to the control of electrical parameters such as l...

In the permanent magnet linear synchronous motor (PMLSM), force ripple is harmful, useless and disturbing. The force ripple is basically composed of two components: detent force and mutual force ripple. This force is influenced by the geometric parameters of the permanent magnet (PM) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stato...

In the present work, an integrated method of pole shape design optimization for reduction of torque pulsation components in permanent magnet synchronous motors is developed. A progressive design process is presented to find feasible optimal shapes. This method is applied on the pole shape optimization of two prototype permanent magnet synchronous motors, i.e., 4-poles/6-slots and 4-poles-12slots.

Accurate modeling of the wind energy conversion system is necessary to design and implementation of the control loop for the generator and the frequency converter, in order to extract maximum power from the wind and to investigate the effects of interconnection between wind farms and power system. In this paper the combination of a permanent magnet synchronous generator loaded with a diode rect...

<p>The development of axial-flux permanent-magnet (AFPM) machines has become a mature technology. The single-stator double-rotor (SSDR) AFPM structure advantages on the compactness and low up to medium power applications so microscale size low-cost are reachable be designed. research main objectives designing manufacturing lateral shifting from north poles first rotor face second (NN) sou...

This paper deals with the optimal control of interior permanent magnet synchronous machine (IPM) in the integrated starter-generator (ISG) application. IPM designed for flux-weakening operations are able to realise high performances. Nevertheless, the ISG environment imposes lots of constraints which must be taken into account in an appropriate control. After a presentation of machine design, I...
