Measurement of Phasor-like Qualities

Devices called Phasor Measurement Units (PMUs) report the values of (for example) amplitude, frequency and phase of the power system. These parameters describe a mathematical entity called a phasor.  But the power system quantities are not phasors—they are 'phasor-like.' Their frequency and amplitude are not constant, and constant parameters are a requirement of a phasor. Further, the word phase is not even defined as a parameter relating two signals of different frequencies, and yet that is a required output of a PMU. This proposed work is based on finding another way to describe the power system that is being measured. It is important because unless a parameter being measured is defined, it is not possible to say whether it is being measured accurately.
