A New PLL Simulation Validation for Three-phase Grid under Heavy Distorted Conditions
نویسندگان
چکیده
The precision of phase-locked loop (PLL) has a direct effect on the output performance for three-phase grid-connected inverter or three-phase active PFC. In this paper, a new three-phase digital closed-loop phase-locked algorithm is proposed on the basis of synchronous reference frame transformation. Synchronous simulation of the PLL techniques is a good choice even if the polluted three-phase grid such as the harmonics, phase jump and unbalance. Finally, MATLAB digital simulation results prove that the proposed PLL can fast and accurately track the positive sequence fundamental components of three-phase grid voltage.

متن کاملFrequency-Adaptive Modified Comb-Filter-Based Phase-Locked Loop for a Doubly-Fed Adjustable-Speed Pumped-Storage Hydropower Plant under Distorted Grid Conditions
The control system of a doubly-fed adjustable-speed pumped-storage hydropower plant needs phase-locked loops (PLLs) to obtain the phase angle of grid voltage. The main drawback of a comb-filter-based phase-locked loop (CF-PLL) is the slow dynamic response. This paper presents a modified comb-filter-based phase-locked loop (MCF-PLL) by improving the pole-zero pattern of the comb filter, and give...
