Steady State Performance

<p>This paper concerns the experimental investigations of the three-phase line commutated SCR inverter fed synchronous motor.  The fabricated system consists of a line-commuted inverter, a three-phase synchronous motor with the excitation winding connected in series to the inverter input, a terminal voltage sensor and a gate-pulse generating circuit. The firing pulses for SCRs of the inverter are generated by the microprocessor in proper sequence with the help of synchronizing signal derived from the terminal voltages of the synchronous machine. The steady state performance characteristics are obtained experimentally using the fabricated system. The experimental results show that a three-phase synchronous motor supplied by a line commutated inverter with the excitation winding connected in series to the dc link provide  excellent characteristics of the conventional dc series motor.</p>

Characteristics Analysis

This paper presents steady-state characteristics analysis of a self-excited single-phase induction generator (SPIG) which supplies an isolated load. The self-regulated characteristics of a SPIG by connecting external capacitors are examined. The system consisting of both shunt and series capacitors in short shunt and long shunt connections to improve voltage regulation of SPIG has been analyzed. Based on two-phase symmetrical components equivalent circuit model, a fast iterative approach to simulate the operated state of a SPIG is developed. To demonstrate the effectiveness of the proposed approach, the approach has been tested on a practical motor-driven SPIG. Very close agreement between experimental and simulated results has been obtained.
