This paper proposes a redefinition of the power system quantities often said to be described by a synchro-phasor and measured by a phasor measurement unit. Problems with what are often called “synchronous phasor measurements” include the facts that they are not truly synchronous, and the quantity being measured is not truly a phasor. This paper proposes a new method of making measurements that overcomes these problems. It tests the proposed definitions and measurement methods with “synthetic” signals, and shows that the method provides understandable and consistent results.
