Abstract
This disclosure relates to an apparatus, computer readable medium and a method for estimating a frequency of an electrical signal. The method comprises converting a first signal having three components into a second signal having two components in accordance with a first transformation, wherein each component of the first signal corresponds to a phase component of a three-phase electrical signal and the two components of the second signal are representative of characteristics of the three-phase electrical signal. The method further comprises filtering the second signal in accordance with a previous frequency estimation. Then the method comprises converting the filtered second signal into a third signal having a single component in accordance with a second transformation, wherein the single component of the third signal is representative of characteristics of the three-phase electrical signal. Finally, the method comprises estimating a frequency of the third signal, wherein the estimated frequency of the third signal is indicative of a frequency of the three-phase electrical signal.
