Data breakpoint resuming method for new energy centralized control system

Abstract

The invention discloses a data breakpoint resuming method for a new energy centralized control system, which comprises the following steps that: when communication is interrupted, a power station caches real-time data, copies and stores a real-time library of a centralized control master station as a real-time library copy at the moment, and records a corresponding communication interruption eventin an inversion control library resumeDB; after the communication is recovered, the compressed file is uploaded to a centralized control main station; the centralized control master station fuses thecompressed file and the real-time library copy to form an inversion packet and complements the communication interruption event; the centralized control main station consumes data in the inversion packet in a periodic micro-batch processing mode according to the completed communication interruption event record and inversion packet, and performs time sequence and time section calculation on the basis of the data to obtain cooked data; and the cached real-time data and the cooked data are stored into a historical library. According to the method, seamless fusion of continuous transmission dataand real-time monitoring historical data is realized, the problem of data loss in a new energy centralized control system is solved, and high requirements of operation and maintenance and analysis services on historical data integrity are met.

Description

technical field [0001] The invention relates to a data breakpoint resume transmission method of a new energy centralized control system, belonging to the technical field of data processing of a new energy centralized control system. Background technique [0002] The main network architecture of the new energy centralized control system, such as figure 1 As shown, the new energy data gateway machine on the power station side (hereinafter referred to as the power station side gateway machine) accesses the data of each subsystem on the power station side, and sends it to the front communication server of the centralized control master station (hereinafter referred to as the centralized control station) through multiple 104 protocol links. The front server of the main station), and then enter the real-time processing server of the centralized control master station in each application collection library (the data of the booster station enters the collection library of the booste...

AI Technical Summary

Problems solved by technology

[0005] The operation, maintenance and analysis business of the new energy centralized control system has high requirements on the integrity of the historical data of the centralized control system. However, in actual projects, the network structure between the main and sub-stations is complex, and most of them use operator networks. There are security access areas, vertical encryption, etc. In many links, the communication stability is not as good as that of the electric power private network, and data loss is inevitable

[0006] When the data flow of the new energy centralized control system passes through the five different links of the new energy substation gateway, the main station front server, the real-time processing server, the history server, and the history database, the data identification systems adopted are different; at the same time, in the real-time The processing of the server link also needs to go through multi-dimensional calculations of time series and time sections, which makes it impossible for the new energy centralized control system to fill in missing data based only on the breakpoint resume technology at the communication level
