The article presents the concept of an electromagnetic circuit generator with permanent magnets mounted on the surface rotor core designed for single phase work. Computation field-circuit model was shown. The spectrum of time course of voltages in the idle work was presented. The cross section with graphically presentation of magnetic induction in particular parts of electromagnetic circuits wa...

Wind energy is a leader area of application for variable-speed generators operating on the constant grid frequency. This paper depicts the power quality enhancement in wind power system using permanent magnet synchronous generator (PMSG) and Quasi Z-source Inverter. The PMSG is connected to the power network by means of a quasi z-source inverter (qZSI). The PMSG are used by these technologies d...

This paper focus on the advancement of SVPWM (space vector pulse width modulation) inverter fed permanent magnet synchronous motor (PMSM).The paper deals with a space vector pulse width modulation (SVPWM) algorithm applied to electrical drives. Anextensive and detailed study of the space vector pulse width modulation design process hasbeen done, that indicate some practical sign for implementat...

Abstract Intermittent power generation of renewable energy system is the active reason affecting stability grid, and adjusting load imbalance between supply through hydrogen production unit main means to reduce impact natural conditions ensure continuous stable supply. In this paper, simulation model permanent magnet direct drive fan for established, wind used achieve effect output power.

In electric power generation, customers want generators with high efficiency. Nowadays, modern turbo-generators have efficiencies greater than 98%. Although this amount should not be obtained for all kind of machines, efficiency will remain one of the main parameters for customer choice. Efficiency is also linked to the life of the machine: the higher the efficiency is, the longer the machine’s...
