This paper mainly studies the PLL algorithms for TCSC, expecting the PLLs to achieve the following performances: rapidly and accurately tracking line current phase and frequency, effectively suppressing sub-harmonics and harmonics, robustness to the disturbances and other types of pollutions. The paper first describes the concept of PLL. Then on the basis of the comparison among several kinds of single-phase PLLs, it presents that the PLL based SOGI-FLL is a more appropriate synchronization scheme for TCSC.
