Synchronous clock system and method for double Beidou satellites

Abstract

The invention discloses a double Beidou satellite synchronous clock system and method, the system comprises a Beidou antenna, a power divider and a double Beidou synchronous clock device, the Beidou antenna is connected with the power divider, the power divider is connected with the double Beidou synchronous clock device, the Beidou antenna is used for receiving satellite signals, and the double Beidou synchronous clock device is connected with the power divider. The power divider divides received satellite signals into two paths of Beidou signals, the obtained two paths of Beidou signals serve as reference source signals, the reference source signals and IRIGB power clock signals are transmitted into the double-Beidou synchronous clock equipment at the same time, and the double-Beidou synchronous clock equipment is used for correcting and compensating deviation of the input IRIGB power clock signals. And reducing the deviation value and then outputting. According to the invention, the technical situation that the existing power grid time synchronization system in China excessively depends on the GPS system is solved, and the safety and reliability of the power grid time synchronization system are improved.

Description

technical field [0001] The invention relates to a power system time synchronization technology, in particular to a double Beidou satellite synchronous clock system and method. Background technique [0002] In recent years, with the rapid development and construction of my country's power system, smart substation equipment has been widely used, and the interconnection of the national power grid is also advancing rapidly, which makes the power system's requirements for time synchronization accuracy more and more stringent. As the core component of the power system function, the time synchronization network provides guarantee for the safe and stable operation of the power system. Its role is to provide a unified and accurate time reference standard for all intelligent devices and central control centers in the power system. [0003] my country's satellite navigation technology research started relatively late, and the research on related terminal equipment is still immature, so...

AI Technical Summary

Problems solved by technology

[0003] my country's satellite navigation technology research started relatively late, and the research on related terminal equipment is still immature, so the satellite timing service of the domestic power system mainly relies on the GPS system. Each time service terminal is a passive one-way receiving GPS time signal mode, it is not easy to realize the time synchronization and unification between various systems
