A Novel Phase locked Loop Scheme for Grid Voltage Synchronisation Using the Energy Operator

摘要

A well-known issue with existing power systems is rapid and accurate synchronisation to grid voltages when the system is unbalanced under grid fault conditions and corrupted with harmonics. This paper presents a novel phase locked loop technique for grid synchronisation technique using the energy operator. A comparative study is undertaken to investigate the accuracy and robustness of this technique compared to existing grid synchronisation techniques.
