SOGI–FLL Based Adaptive Filter for DSTATCOM Under Variable Supply Frequency

Journal of the Institution of Engineers (India): Series B, 2016
This paper presents an adaptive filter based on second order generalized integrator–frequency locked loop (SOGI–FLL) for distribution static compensator (DSTATCOM) operating under variable supply frequency with nonlinear load. It is observed that under variable supply frequency, the FLL provides an excellent frequency tracking performance.

An Enhanced Virtual Inertia Control Strategy Based on an Improved SOGI-FLL Scheme for Energy Storage Converters

2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021
A frequency derivative-based virtual inertia method for energy storage converters (ESCs) using a second order generalized integrator-frequency locked loop (SOGI-FLL) is used to address the lack of inertia concern. However, the existence of the dc component in the input of the SOGI-FLL leads to fundamental frequency oscillations in its measured results.

Fuzzy sliding mode observer with dual SOGI-FLL in sensorless control of PMSM drives

ISA Transactions, 2019
To improve the performance of permanent-magnet synchronous motor (PMSM) drives, a sensorless control scheme based on a sliding mode observer (SMO) with a fuzzy logic controller (FLC) and a dual second-order generalized integrator-frequency locked loop (DSOGI-FLL) is proposed in this paper.

A SOGI-FLL-Based Type-3 Synchronization System for Single-Phase Grid-Connected Applications

IEEE Transactions on Industrial Electronics
Synchronization systems are crucial for the efficient functioning of grid-connected power converters, typically designed around the phase-locked loop (PLL) concept. While type-2 PLLs are commonly featured in literature, the need for enhanced phase tracking, such as in applications like more-electric aircraft, necessitates the exploration of type-3 PLL ...

ARM based implementation of sogi-fll method for power calculation in single-phase power system

2017 5th International Conference on Electrical Engineering - Boumerdes (ICEE-B), 2017
For the proper and stable operation of a microgrid, an accurate estimation of the key parameters under various disturbances is the most important task for the rest of the control blocks. In this paper, a SOGI-FLL scheme aimed for voltage and current parameters estimation in single-phase power system is implemented using high speed ARM microcontroller ...
