Frequency Locked Loop in Estimating Active, Reactive and Apparent Powers

Frequency Locked Loop in Estimating Active, Reactive and Apparent Powers

Meris Lihić, Slobodan Lubura

In this paper, a new power calculation method has been presented. This method is based on a second-order generalized integrator frequency locked loop (SOGIFLL) and has enhanced features over classical methods for power calculation widely used in industry. The FLLs have a wide variety of applications such as power
converters, grid synchronization, sensorless flux estimation, and control of motor drives. The nature of the FLL allows for it to be a potentially perfect calculation method for power calculation. The obtained results showcase the effectiveness of the proposed power calculation method.
