Embodiment Construction

[0017] It is known that the code slip period of the synchronous equipment is calculated by the frequency deviation. When the frequency deviation is better than ±1E-13, the calculated code slip period is 20 years, that is, the code slip will not occur when the synchronous equipment is returned, so Only need to make the frequency deviation between different main reference clocks PRC in the whole network better than ±1E-13, it can be considered as full synchronization.

[0018] Based on the above principles, the scheme adopts the method of controlling the frequency deviation of network operation, that is, using the existing frequency standard system to compare with the PRC main reference clock to improve the accuracy of the comparison. For the frequency deviation among the PRCs, adjust the PRC according to the deviation so that the frequency deviation is better than ±1E-13. The schematic diagram of the system structure is attached figure 1 As shown, the dotted line box in the fi...

Abstract

The invention relates to the field of electric power communication synchronization network full synchronization, in particular to an electric power communication synchronization network full synchronized evolution method by using Beidou two-way communication features. The method is used for changing the conditions that a plurality of large synchronization zones and a plurality of primary reference clocks (PRC) separately running exist in the current synchronization network and solving the problem that synchronization hidden troubles exist in the communication among the synchronization zones, especially solving the communication problem caused by non-synchronization of an electric power communication special network and other operator communication networks.

Description

technical field [0001] The invention relates to the field of full synchronization of electric power communication synchronous network, in particular to a full synchronous evolution method of electric power communication synchronous network utilizing Beidou two-way communication characteristics. It is used to change the situation that there are multiple large synchronization areas and multiple independently operating main reference clocks PRC in the current synchronization network, and solve the problem of synchronization hidden dangers in the communication between each synchronization area, especially the communication network between the power communication private network and other operators Communication problems caused by out-of-sync to achieve network-wide synchronization. Background technique [0002] Synchronization network for communication in foreign countries started early and has been fully researched, and has been relatively perfect after years of construction. ...
