Synchronization is one of important operation in each substation with the complicated measurement of frequency difference and voltage difference. In order to improve the synchronization efficiency, this article introduces a new -algorithm of synchronization based on the voltage signal analysis of on substation synchronizing manipulation. Different with the traditional algorithms, this new one features less manipulation data, higher synchronization speed and precision and strong ability of anti-jamming. So it is a good application for power substations. This article also analyses some common problems and brings forward an integrated solution to these problems.
