Abstract:
A system for synchronizing a first phase angle of a power source with a second phase angle of a power grid, said system comprising:a first portion which receives a grid voltage from said power grid and which uses said grid voltage to calculate said second phase angle; a second portion which is communicatively connected to said first portion, which receives said calculated second phase angle, and which uses said second phase angle to calculate a grid voltage frequency; a third portion which is communicatively connected to said second portion, which receives said calculated grid voltage frequency, and which uses said grid voltage frequency to generate an increment angle; a fourth portion which is communicatively connected to said first portion, which receives said second phase angle, and which generates an initial angle based upon said second phase angle; and a fifth portion which is communicatively connected to said third and fourth portions, which selectively receives said increment angle and said initial angle, and which uses said received increment and initial angles to generate said first phase angle having a value that is substantially identical to said second phase angle.
