Providing time synchronization signals for power network automation devices such as fault recorder, event recorder, microcomputer relay protection device, microcomputer measurement and control device, merging unit, intelligent terminal and various safety automatic devices, telecontrol and microcomputer monitoring system, dispatching control system, etc.
The standard clock used for frequency monitoring, means the system frequency error accumulation is compared with the schedule by the difference between the power frequency clock and the standard time.
The synchronous clock used for phase measurement, the GB8007 is used for synchronizing the sampling pulse, and the synchronization error is very small, which can ensure the accuracy of phase measurement.
For fault location, especially for the development of dual-terminal traveling wave ranging principle of the device to create conditions.
For relay protection device test, inspection line longitudinal protection (high frequency phase difference protection device).
FEATURES
Independent GPS/BeiDou binary system has wide signal coverage, high signal intensity and convenient distributed installation. Especially suitable for power plant, substation, communication base station and other equipment time synchronization.
All-weather signal coverage, independent two-star system each other to ensure a long continuous high-precision timing.
Multiple 32-bit high-speed microprocessors + large-scale integrated FPGA chips, parallel high-speed data processing and various code, excellent performance.
High-precision punctuality frequency is derived from adaptive synchronization technology, closed-loop control punctuality technology to tame constant temperature crystal oscillator, to achieve long-time high-precision punctuality.
Automatic selection of clock source according to priority, when receiving and decoding external IRIG-B (DC) code, automatic delay compensation correction technology is used to improve timing accuracy.
Separate 10 M/100M network ports (each port has a separate MAC address), flexible configuration, can be used in different sub-nets or different physical isolation networks, using NTP/SNTP protocols to provide time synchronization services.
