  • Fuse Protection against the Regenerative Circuit Internal Commutation Fault
    Dr. Hidaia Mahmood Alassouli
    Current-limiting fuses are widely used to protect the thyristors in dc drive systems. In the event of the commutation failure when regenerating (inverting), the fuses need to interrupt in loop supplied by the ac and dc voltages acting in series which is the most difficult case for protection by fuse.In this paper, a detailed study of the complete interruption process has been i...

  • Reactive Power Compensation
    Dr. Hidaia Mahmood Alassouli
    Power systems have two components of apparent power: active and reactive power. Both components are necessary for functioning of electrical systems. The active power is the average power absorbed by the resistive load. The reactive power is the measure of energy exchange between the source and reactive power of load. Energy storage devices do not dissipate or supply power, but ...
