Protection fault information processing system based on dynamic load balance and mutual hot backup

Abstract

The invention discloses a protection fault information processing system based on dynamic load balance and mutual hot backup, which can cause a master station system to adjust concurrent data processing in the master station system in real time in accordance with load conditions. The technical scheme is as follows: the system comprises a dispatching machine and a plurality of preposed processors, wherein the dispatching machine is connected with each preposed processor; the dispatching machine is connected with an online client-side so as to sort and allocate external data processing requests to the preposed processors uniformly in accordance with a dynamic allocation principle and then perform task adjustment and secondary allocation in accordance with response conditions; and a symmetrical system structure is formed among the preposed processors, and each preposed processor separately provides services for the outside and processes the data requests after receiving the data processing requests allocated by the dispatching machine.

Description

Technical field [0001] The invention relates to a fault information processing system, in particular to a system for processing protection fault information on the dispatch end of a power system. Background technique [0002] In the power system, the protection information management main station system runs on the dispatching side. On the one hand, it communicates with the protection information management sub-station of the plant side through the data network to obtain real-time operation data of the related secondary equipment at the plant side. Each on-line terminal of the master station system of the terminal protection information management can query the historical data of the master station and related information of the secondary equipment at the plant station in real time, and can perform statistical analysis on the historical fault information of the master station's power grid through various fault data models. figure 1 Shows the structure of the traditional protection...

AI Technical Summary

Problems solved by technology

[0005] 1. The central server of the main station system can only rely on the server itself to perform corresponding data backup work. If the central server of the main station system fails, it is difficult to recover in a short time

[0006] 2. With the obvious increase in the number of connected factories and stations, a large amount of concurrent data processing will inevitably occur. Therefore, it is required that the central server of the main station system must have the ability to provide a large amount of concurrent data processing

In this way, the concurrent data processing capability of the central server of the main station system has become a technical bottleneck for the stability of the main station system

[0007] 3. With the increase of applications and demands on the scheduling side and the rapid accumulation of historical faults, fault analysis based on historical fault data is becoming more and more important. The slow processing of large data volumes will directly affect the data access efficiency and response of online clients degree
