Powers And Compensation In Three-Phase Systems With Nonsinusoidal And Asymmetrical Voltages And Currents, Prashanna Dev Bhattarai
LSU Doctoral Dissertations
A contribution to power theory development of three-phase three-wire systems with asymmetrical and nonsinusoidal supply voltages is presented in this dissertation. It includes: • contribution to explanation of power related phenomena • contribution to methods of compensation The power equation of unbalanced Linear Time Invariant (LTI) loads at sinusoidal but asymmetrical voltage is first presented. The different current components of such a load and the phenomenon associated with these current components are described. The load current decomposition is used for the design of reactive balancing compensators for power factor improvement. Next, the current of LTI loads operating at nonsinusoidal asymmetrical …
Working Active Power, Reflected Active Power, And Detrimental Active Power In The Power System, Tracy Nakamura Toups
Working Active Power, Reflected Active Power, And Detrimental Active Power In The Power System, Tracy Nakamura Toups
LSU Master's Theses
Study of decomposition of the active power into components with deeper economical meanings, namely working active power, reflected active power, and detrimental active power is the subject of the thesis. The decomposition of active power will be based on the Current’s Physical Component (CPC) Theory. Working active power is equivalent to useful power that is the rate of energy used to do work, such as mechanical power. Reflected active power is the rate of energy transfer that the load sends back to the supply which dissipates off the supply resistance. This reflected active power is not taken into account on …
Development Of An Algorithm For Switching Compensator Control Based On The Currents' Physical Components Theory, Samuel Pearce
Development Of An Algorithm For Switching Compensator Control Based On The Currents' Physical Components Theory, Samuel Pearce
LSU Master's Theses
Development of a three-phase switching compensator algorithm, based on the Currents’ Physical Components (CPC) power theory and capable of performing in real time, is the subject of this thesis. The compensator algorithm could be implemented to control a PWM Inverter, which would perform as a shunt switching compensator of harmonic, reactive and unbalanced currents or a customizable combination of the three. The hardware used to demonstrate the ability of the algorithm to perform within the restraints or real time operation is a Motorola DSP56F807 evaluation mode DSP board and a set of voltage and current sensors. The Evaluation Board was …
