Impact of PLL Frequency Limiter on Synchronization Stability of Grid Feeding Converter
IEEE Transactions on Power Systems, 2022It is well known that grid-feeding converters that synchronize to the grid through a Phase-Locked Loop (PLL) can become unstable after a fault. An often-neglected element that plays an important role in the converter synchronization stability is the PLL ...

2012 IEEE/AIAA 31st Digital Avionics Systems Conference (DASC), 2012
• Local oscillators/hardware clocks operate at slightly different rates, thus, they drift apart over time. • Local logical clocks, i.e., timers/counters, may start at different initial values. • The synchronization problem is to adjust the values of the local logical clocks so that nodes achieve synchronization and remain synchronized despite the drift

Synchronization Stability Analysis of Grid-Forming Inverter: A Black Box Methodology
IEEE transactions on industrial electronics (1982. Print), 2022Driven by the demands of carbon footprint reduction, the conventional fossil-based generators are gradually being replaced by grid-forming inverter. One crucial aspect of grid-forming inverter is synchronization stability, which is not only related to ...

An Adaptive Synchronous Machine Stabilizer
IEEE Power Engineering Review, 1986An adaptive synchronous machine stabilizer utilizing the least-squares identification with varying forgetting factor and a self-searching control strategy is proposed in this paper. The use of varying forgetting factor in the identification algorithm improves parameter tracking under both transient and dynamic conditions, and the use of a self ...
