Power Network Port Measurements Synchronization

This work introduces a new procedure for software synchronization of electrical power signals collected over a large geographical area. The idea is to use not necessarily synchronized, but stable, local clocks, and synchronize the sparsely collected data windows by an offline procedure. An approach for the estimation of non monitored internal system buses serves as a basis for the synchronization process. The electrical power network description yields the desired phase corrections, compensating the loss of data window synchronism. Typical sub determined situations are avoided by a proposed alternative network monitoring scheme, illustrated by a case example. Simulation results emphasize the method robustness with respect to usual network parameters uncertainties.
