Electromagnetic mechanism of synchronous operation of the brushless doubly-fed machine
IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002The brushless doubly-fed machine is a machine which incorporates the robustness of the squirrel cage induction machine and the speed and power factor control of a synchronous machine. The electromagnetic environment within the brushless doubly-fed machine is investigated using simple formulae in order to develop an intuitive feel for the mechanism ...

A brushless generation system for microgrid operation utilizing dual stator induction generator
2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014Modern micro-grid needs to integrate all possible and economically attractive renewable energy resources. In many cases these generations are not smooth in nature and are situated in remote locations where regular maintenance is difficult. This paper proposes a brushless generation system using a dual stator winding induction generator (DSWIG).

Analytical and experimental modeling of brushless excitation system at normal operating conditions
2005 IEEE Russia Power Tech, 2005In this paper, modeling and identification of the excitation system in the thermal unit #3 of Touss power plant in Iran is presented. Two approaches of modeling, i.e. analytical and experimental modeling are used. In the analytical method, first, using the documents and circuit diagrams in the power station, a block-diagram for excitation system was ...

Sensorless operation of brushless DC motor drive designed for air conditioners
2017 International Conference on Innovations in Electrical, Electronics, Instrumentation and Media Technology (ICEEIMT), 2017This paper presents the simulation for sensorless operation of BLDC motor drive with speed control, designed for Air conditioners. As the motor starts to rotate back EMF is obtained from the motor terminals using a voltage divider along with a low pass filter. Control pulses for inverter are generated based on the zero crossing of back EMF. The results

Modelling a laminated brushless exciter-alternator unit in all modes of operation
IEE Proceedings B Electric Power Applications, 1991The brushless exciter is now widely used in alternator excitation systems as it offers the advantage of reduced maintenance. An accurate modelling of the exciter-alternator set is important for design and operation engineers. In the paper, an accurate detailed model of the set is presented. The exciter is modelled as a synchronous machine in the direct
