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 collection, processing and storage services are the basic functions of distribution automation systems, and also the basis for advanced applications such as automatic processing of feeder faults, real-time topology analysis, and dynamic grid coloring. In the case of a large capacity, stress testing, that is, simulating a large number of remote signaling and telemetry changes in a short period of time, may cause the distribution automation system to lose real-time data. At this time, it is necessary to switch computer nodes or communication links. Real-time data is also lost. A common method used in power distribution automation systems to prevent data loss is to use...
