Satellite synchronous master clock device

Abstract

The invention discloses a satellite synchronous master clock device, comprising a satellite time source module, a time source control module, a central control module, a display and control system, an output module, a time source detection module and a spreading device module, wherein the satellite time source module, the time source control module, the output module, the spreading device module, the time source detection module, the display and control module are connected with the central control module by motherboard buses, and the satellite time source module, the output module and the time source control module are connected by motherboard buses. By acquiring a satellite standard time signal, a local clock is adjusted to control time difference within a certain precision range so as to provide a standard time source for a peripheral. In addition, the invention also provides a set of independent, reliable and accurate distribution and control system with uniform time for units at different levels in a power system.

Description

technical field [0001] The invention relates to a time synchronization technology, in particular to a satellite synchronous master clock device. Background technique [0002] At present, the distribution of transmission terminals and receiving terminals in the power system is widely and scattered. There are real-time clocks inside the automation devices, or there are timing devices based on GPS (Global Positioning and Navigation System) in the stations, and the inherent errors are unavoidable. As the time increases, the accumulated error will become larger and larger, and the correct time measurement function will be lost. [0003] With the improvement of the technical level of power grid operation, most substations adopt comprehensive automation solutions, and remote centralized control and operation, which not only improves labor productivity, but also reduces the possibility of misoperation. Therefore, the time synchronization requirement of the real-time clock of the au...
