Abstract: | This paper presents frequency feedback loop based Cascaded Delayed Signal Cancellation PLL employed for dynamic voltage restorer (DVR) application to compensate grid voltage disturbances. The primary and key function of PLL is continuous tracking of grid voltage angle in a precise manner and feed it to DVR control. The conventional CDSC-PLL performance during frequency variation is poor which affects the estimation of grid voltage angle and thereby leads to maloperation of DVR control. Thus in this paper FFL is added to the CDSC-PLL to adapt for frequency variations for effective operation of DVR control. The performance analysis of FFL based CDSC-PLL is presented for various disturbances. Finally, FFL based CDSC-PLL is incorporated in the 10 kV, DVR system and the simulation results of the system for different voltage disturbances by using MATLAB/SIMULINK. © 2020 IEEE. |
