According to the definition of power measurement, the active power and reactive power
of the fundamental and each other harmonic can be expressed as:
EQUATION C-39:
EQUATION C-40:
Substituting Equation C-31, C-32, C-33 and C-37 into Equation C-39 and C-40, the
power of each harmonic component can be obtained with the following:
EQUATION C-41:
EQUATION C-42:
Total active power and reactive power can be expressed as:
EQUATION C-43:
EQUATION C-44:
