【 摘 要 】

By deploying the TMU device at stations and power plants, the time synchronization measurement of the station clock device and secondary device are performed. The automatic discovery of the device status and the real-time upload of the time difference data are realized based on the IEC61850 protocol. The time synchronization network configuration, alarm and performance datas are unified maintained, managed and monitored, to enhance the plant station time synchronization precision control ability, which has a good operability, scalability and compatibility.
