Abstract
This paper presents an analysis of two stationary-frame fundamental positive sequence component detecting approaches applied to synchronous reference frame phase locked loop. The two approaches include selective band pass filter(SBPF) and double second order generalized integrator based positive sequence calculator(DSOGI-PSC). Derivation of the SBPF from a new perspective reveals that the SBPF is equivalent to the d-q method that adopts a first-order low-pass filter on the low pass filtering link. The performance of the SBPF and the DSOGI-PSC is compared de-tailedly by theory and simulation under different voltage conditions. Theoretical analysis and simulation results prove that the performance of the SBPF extremely approximates to that of the DSOGI-PSC in addition to a weaker attenuation for fundamental negative sequence signals when the both have a same parameter.关键词
