A new energy centralized control system data breakpoint resume transmission method

Abstract

The invention discloses a data breakpoint resume transmission method of a new energy centralized control system. When communication is interrupted, the power station caches real-time data, copies and saves the real-time database of the centralized control master station at that time as a real-time database copy, and resumeDB in the inversion control database Record the corresponding communication interruption events in the system; after the communication is restored, upload the compressed file to the central control master station; the centralized control master station fuses the compressed file and the real-time library copy to form an inversion package, and completes the communication interruption event; According to the completed communication interruption event records and inversion packets, the master station consumes the data in the inversion packets in the form of periodic micro-batch processing, and performs timing and time-section calculations on the basis of the data to obtain cooked data; the cached real-time Data and cooked data are stored in the historical database together. The invention realizes the seamless integration of continuous transmission data and real-time monitoring historical data, solves the problem of missing data in the new energy centralized control system, and satisfies the high requirements of operation and maintenance and analysis services on the integrity of historical data.

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
