结合变电站运维管理的工业现场特点，和无线传感器网络时间同步协议的研究，提出了汇聚节点的双向时间同步定时偏差补偿与传感节点虚拟双向同步相结合的时间同步算法。在网络部署的初期，按照模型布置网关节点和汇聚节点，汇聚节点和传感节点采用不同的时间同步方法。仿真实验表明网络收敛时间和同步精度具有良好性能。

With respect to the characteristics of industrial operation/maintenance management of substations and research on wireless sensor network time synchronization protocol, this paper presents a time synchronization algorithm combining the timing deviation compensation of the bidirectional time synchronization at aggregation nodes and the virtual bidirectional synchronization at sensor nodes.In the early stage of the network deployment,gateway nodes and aggregation nodes are arranged according to the model,and aggregation nodes and sensor nodes use different time synchronization methods.Simulation experiments show that this method has good network convergence time and synchronization precision.
