Case3:General Case
Denoting and :
Equation(1):
Define a reference quantity such as the terminal voltage (t) and other quantities are synchronized to it.
To compute phase angle of the DVR voltage, a fundamental of line current is extracted with respect to reference
quantity.
DVR voltage is then synthesized using magnitude from the equation(1) and phase angle that leads the
fundamental of the line current by .
