Embodiment Construction

[0022] Such as figure 1 As shown, a time-serving device 1588 self-adaptive time synchronization method includes steps:

[0023] S100: Connect the 1588 message to the time service device respectively through multiple time service networks, wherein the time service device has a built-in local clock.

[0024] The full name of 1588 is "Precise Clock Synchronization Protocol Standard for Network Measurement and Control Systems", which is a general specification to improve the timing synchronization capability of network systems. It is mainly compiled with reference to timing networks, so that distributed communication networks can have strict timing synchronization. And applied to industrial automation systems. The basic idea is to synchronize the internal clock of the network device (client) with the main clock of the master computer through hardware and software, and provide an application with a synchronization establishment time of less than 10 μs. Specifically, the time serv...

Abstract

This invention provides a self-adaptive time tick method and system of a being-timed device 1588. The method comprises the following steps: accessing 1588 messages to the being-timed device through a plurality of time service networks; performing parallel synchronization to the input 1588 messages to perform identification and time mark in a plurality of time service networks; according to a 1588 protocol, acquiring precise time tick time of each time service network; inputting the precise time tick time of each time service network to a local clock of the being-timed device; acquiring the running state information of the being-timed device; and according to the precise time tick time of each time service network and the running state information, dynamically adjusting a preset following strategy so as to perform self-adaptive adjustment to the time service network selected by the time service device. In the whole process, 1588 messages are transmitted at the same time by redundant multi-networks; and the time service device is adjusted in a self-adaptive way to select the time service network so that the time service reliability is improved effectively.

Description

technical field [0001] The present invention relates to the technical field of electric power systems, in particular to a method and system for adaptive timing of the timed device 1588 . Background technique [0002] With the continuous development and progress of substation automation technology, smart substations provide the basis for various advanced applications due to the adoption of information digitization, and have become the main direction of substation automation technology development. [0003] IEC61850 has a clear definition of the network level of intelligent equipment after substation digitalization. The information exchange between process layer and bay layer equipment replaces traditional substation primary equipment (such as AC sensors and circuit breakers) and secondary equipment (such as relay protection, automation, etc.) The signal connection between devices) has high requirements for safety and reliability. [0004] Due to the digitalization of signal ...
