| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 91 === With the widespread use of nonlinear loads nowadays, the system voltages and currents may be imbalanced and distorted. Traditionally, the definition of power components and the power factor are under the balanced and distortionless voltage and current waveforms. However, the conventional definitions for such power quantities need to be redefined if the voltage and current are no longer ideal.
This thesis intends to give an literal overview for the definitions of power components and the power factor under imbalanced and/or distorted waveforms for both single- and three-phase system. To verify the usefulness of those reviewed approaches for the new definitions, four test cases are studied for comparison purpose.
