GF8007 BeiDou/GPS Binary Multi-source time Synchronization Server
IDescription
The GB8007 time synchronization system provides accurate synchronization time signals to various power system automation devices by using the second synchronization signals and time information messages sent by Beidou navigation system, GPS( GPS) satellites.
Ifeatures
1. 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.
2. All-weather signal coverage, independent two-star system each
other to ensure a long continuous high-precision timing.
3. Multiple 32-bit high-speed microprocessors + large-scale
integrated FPGA chips, parallel high-speed data processing and
various code, excellent performance.
4. 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.
5. 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.
6. 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.
7. Having two PTP V2 high-precision timing ethernet interfaces
while down-compatible with V1 protocols, telecom-level timing
accuracy, support multicast and unicast transmission modes, and
support the best master clock selection algorithm.
8. Time interface using plug-in structure, users can be customized
based on demand, a variety of configuration methods, it’s
convenient to manage and upgrade.
9. Providing group programmable pulse, each group can be set
separately to PPS, PPM, PPH, flexible and convenient.
10. High performance, wide range switching power supply, AC-DC
compatible input, convenient and reliable, stable operation.
11. All signal input and output interfaces are photoelectric
isolation measures, safe and reliable.
12. 3U Frame structure, 19 inch standard chassis, plug-in
functional interface module, easy installation and maintenance.
Iapplication
1. 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.
2. 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.
3. 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.
4. For fault location, especially for the development of
dual-terminal traveling wave ranging principle of the device to
create conditions.
5. For relay protection device test, inspection line longitudinal protection (high frequency phase difference protection device).
