It is widely applicable to various power plants, conventional substations, and intelligent substations.

　　1. Redundant input of multi-source signals

　　The power time synchronization device supports the access of multiple external time signal sources, which can automatically identify and switch available signal sources. It can also manually customize priority strategies to reduce the timing impact caused by the interruption of a single signal source and ensure the continuous availability of the timing link.

　　Compatible with commonly used external timing signal access methods, it can adapt to existing timing network architectures on site without requiring significant changes to the original wiring system.

　　2. Multi type timing signal output

　　The professional power time synchronization device is equipped with rich hardware interfaces and network protocol output capabilities, covering the mainstream time synchronization requirements on the power site. One device can meet the time synchronization needs of multiple types of terminals throughout the station:

　　Network timing: compatible with mainstream network timing methods such as NTP network timing and PTP precision time protocol;

　　Adaptation terminal: It can connect various power equipment such as station protection devices, merging units, recording devices, servers, measurement and control terminals, etc.

　　3. Stable punctuality and time-frequency processing capability

　　The power time synchronization device is equipped with a mature time-frequency processing architecture and a high stability timing module, with excellent performance in normal timing; When the external timing signal is temporarily interrupted, the equipment can independently maintain stable time output to ensure that the timing of the station equipment is not disrupted during critical periods.

　　The device is equipped with an adaptive calibration mechanism, which can smoothly correct the timing drift caused by long-term operation of the device, suitable for long-term uninterrupted online operation scenarios.

　　4. Industrial grade hardware adaptation to on-site environment

　　In response to the complex electromagnetic environment and large temperature and humidity fluctuations in power rooms and substation control rooms, the power time synchronization device adopts industrial grade hardware design:

　　4U standard rack structure, solid body structure, suitable for long-term cabinet fixed installation;

　　Support dual power backup architecture to reduce the probability of single point power failure;

　　Suitable for wide temperature working range, with good anti-interference ability, and adaptable to complex working conditions on power sites.
