Abstract

Aiming at the shortage of traditional phase-locked method in the three-phase unbalanced conditions of power grid, this paper proposed a novel software phase-locked loop control strategy. This paper introduces in detail the working principle and designing method of the digital PLL by comparative experiment. The experimental results demonstrated that the new method is feasible and robust. In conclusion, the new control algorithm can quickly and accurately detect the correct phase voltage.
