Transformer substation real-time data rapid distribution synchronization system and method based on edge calculation

Abstract

The invention discloses a transformer substation real-time data rapid distribution synchronization system and method based on edge computing, a real-time data packaging module and a data distributionmodule are deployed on a monitoring host, and a data receiving and processing module are deployed on a monitoring standby machine and a comprehensive application server; the real-time data packaging module provides a series of synchronous interfaces, performs unified encapsulation on the real-time data message and the corresponding processing process, forms a synchronous data packet and loads thesynchronous data packet to the data synchronous buffer pool; the data distribution module is used for establishing a data synchronization buffer pool for a process needing to send synchronization dataon the monitoring host and quickly distributing the synchronization data to other synchronized equipment; and the data receiving and processing module receives the synchronous data message and carries out localized calling after packaging, thereby realizing consistency synchronization of real-time data and a processing result of the synchronized equipment and the remote monitoring host. The datasynchronization efficiency is greatly improved; a real-time data synchronization function can be completed only through a small amount of configuration, and the maintenance workload of operation and maintenance personnel is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of substation automation, in particular to a system and method for rapid distribution and synchronization of real-time data of substations based on edge computing. Background technique [0002] With the continuous development of the application functions of the substation monitoring system, the number of station control layer equipment continues to increase. The hardware composition mainly includes monitoring hosts and comprehensive application servers, and the monitoring hosts generally include 2 or more. In order to meet the normal operation of application functions on different devices, consistent access to real-time data has become one of the essential basic functions of the integrated monitoring system. [0003] In order to ensure the synchronization of real-time data between multiple hosts in existing substations, the method of synchronizing real-time databases or relational databases is often used, th...

Problems solved by technology

From the point of view of practical application, this method can meet the requirements of consistent data access of the main and standby machines, but it has high requirements on the processing capacity of the host. Distribution and synchronization operations consume a lot of resources, and the data synchronization operation can only be performed after the real-time data processing is completed, which has a great impact on the synchronization delay of real-time data, especially when the amount of data is large, the performance bottleneck is particularly obvious
