  • A DSP controlled resonant active filter for current harmonic mitigation in three-phase power systems

    Creator:
    Ünsal, Abdurrahman
    Abstract:
    Power quality has become an important concern to both electric utilities and end users due to the increased use of non-linear loads in modem power systems over the past decade. Nonlinear loads inject harmonics into the power system and thus may lead to poor power quality and lower power factor....

  • Active power filter for the cancellation of harmonic line current distortion

    Creator:
    Merk, Marcel
    Abstract:
    With the increased attention on high efficiency and energy savings, power electronic energy conversion equipment is increasingly incorporated in all levels of the power system. The drawback of such equipment is the generation of nonsinusoidal currents in the power distribution network due to the nonlinear operation. Harmonic currents may distort...

  • Power quality simulator for commercial office buildings

    Creator:
    Atluri, Prabha Krishna
    Abstract:
    The distortions of input voltage and current waveforms generated by switch mode power supply (SMPS) operation are a major cause of concern in the power quality performance of commercial office buildings. These distortions are usually evaluated by performing a site survey of the building. In this thesis, a power quality...

  • Investigation and mitigation of the adverse effects of PWM adjustable speed drives

    Creator:
    Zhang, Haoran
    Abstract:
    With the introduction of high speed semiconductor power devices and the increased application of adjustable speed drives (ASDs) for efficient speed control of ac motors, there has been a growing number of costly motor-drive related process failures. It has been found that the high dv/dt and high switching frequency have...

  • A comparison and assessment of hybrid filter topologies and control algorithms

    Creator:
    Chen, Lijun
    Abstract:
    The harmonic problem in power systems is gaining more attention as incidences correlated with harmonics increase. Conventional passive filtering techniques for harmonic mitigation have inherent problems, and purely active filters have the disadvantages of higher costs and ratings. Hybrid active filters inherit the efficiency of passive filters and the improved...

  • Reactive power optimization using adaptive excitation control of synchronous power

    Creator:
    Al Hamrani, Majed M.
    Abstract:
    Synchronous machines provide a practical way to control reactive power consumption of a plant. One of the main advantages of using synchronous motors in a plant is their ability to generate reactive power for plant loads. A new control scheme for synchronous motor excitation systems is developed to automate reactive...

  • A remotely controlled power quality test platform for characterizing the ride-through capabilities of adjustable speed drives

    Creator:
    Matheson, Evelyn
    Abstract:
    With the increased attention on high efficiency and controllability of industrial processes, as well as reduced weight, volume and cost of consumer products, the applications of nonlinear power electronic converters such as adjustable speed drives (ASDs) are showing a rapid rise. Power Quality (PQ) is becoming an increasing concern with...
