AbstractAccording to the requirements and characteristics of wireless recording system in transformer substation, the feasibility of Referenced Broad Synchronization (RBS) algorithm is analyzed. As the RBS has large overhead and poor fault tolerance, an improved RBS algorithm based on the best linear is proposed. The improved RBS algorithm establishes a new synchronization model on the basis of the system features and reduces the synchronization cost. It estimates clock offset and clock skew by using the minimum variance unbiased (MVU) estimation to compensate for the time, and also improves the synchronization accuracy by filtering abnormal data points. The simulation results demonstrate that the improved RBS algorithm can effectively reduce the number of exchange times of synchronization messages and improve the synchronization accuracy.
