Grid synchronization using fixed filtering with magnitude and phase compensation

This paper describes a grid synchronization technique for single phase systems using only fixed filtering and compensation networks. Compared with other phase locking techniques, the proposed approach has the advantage of requiring no feedback control and a simplistic and predictable design. The paper uses test scenarios and metrics described in IEEE C37-118.1 for testing phasor measurement units (PMUs) to evaluate the performance of the proposed method. The dynamic response of the proposed approach is compared with the second order generalized integrator phase locked loop (SOGI-PLL) and second order generalized integrator frequency locked loop (SOGI-FLL).
