Abstract

The invention discloses a data loss prevention processing method. The data loss prevention processing method comprises steps including firstly, acquiring data, secondly, processing the data, thirdly, caching the data, fourthly, entering the data into a real-time database, fifthly, comparing the data, sixthly, storing the data into local files, and seventhly, entering the data into a history database. The method has the advantages that 1, data cache is carried out according to optimal caching time, loss of the data is avoided assuredly, operation indexes of a system are guaranteed, and standard requirements of the power industry are met, 2, after changeover of a front-end processor of an automatic power distribution system, the data is compared, loss of the data can be prevented assuredly, and the same data is prevented from entering the real-time database, and 3, a two-level storage mode is adopted, accordingly, data loss due to abnormal conditions such as connector failure or connection errors of a commercial database is avoided, and data safety and system reliability of the system are further improved.

Description

Technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a data loss prevention processing method suitable for a large-capacity power distribution automation system with more than 400,000 data collection points. Background technique [0002] Data acquisition, processing and storage services are the basic functions of the distribution automation system, and are also the basis for realizing advanced applications such as automatic feeder fault processing, real-time topology analysis, and grid dynamic coloring. In the case of high-capacity stress testing, that is, to simulate a large number of remote signaling and remote measurement changes in a short period of time, it may cause the distribution automation system to lose real-time data. At this time, the computer node or communication link must be switched. The switching process is generally Real-time data will also be lost. The common method used in the distributio...
