Abstract
The optimal time source can provide accurate, stable and continuous time signal output for the time synchronization system, and ensure the power system to operate under a reliable time reference. Aiming at the problem that single time source in substation cannot meet the reliability requirement of system operation on time synchronization, this paper proposes an optimization algorithm of time source selection under the condition of multiple time signal sources input. Firstly, the validity of the time source signal is tested to determine whether the time signal is valid. The priority test is carried out for the effective time source from the aspects of time signal persistence and stability. Finally, the optimal time source is determined by the weighted synthesis method.
