  The earlier work of the author on Frequency estimation in three-phase power
systems ( that is included as the reference number 1) is expanded to the
distributed setting in order present a framework for the implementation of such
a frequency estimator in real-world power distribution networks. For rigor, the
mean and mean square performance of the distributed frequency estimator is
analysed. The performance of the developed algorithm is validated through
simulations on both synthetic data and real-world data recordings, where it is
shown to outperform standard linear and the recently introduced widely liner
frequency estimators.
