Comprehensive power system real-time data management method based on memory key value database

Abstract

The invention provides a comprehensive power system real-time data management method based on a memory key value database. The comprehensive power system real-time data management method comprises thefollowing steps that a, enabling a comprehensive power system physical domain to obtain a field periodic measurement value as an original data source of an information domain energy management subsystem; b, transmitting the original data of the equipment to a sub-system area controller in a centralized manner through a sub-system area field data network / bus; c, enabling the subsystem area controller to analyze and process the equipment on-site original data in the area, and storing a key value data model in a lower computer memory key value real-time database; and d, periodically reading thelower computer memory key value real-time database of the region by each subsystem according to the data management requirement of the region. The timeliness and the transverse expandability of real-time data management are guaranteed through the memory key value database technology.

Description

technical field [0001] The invention relates to the technical field of real-time data management, in particular to a method for real-time data management of an integrated power system based on a memory key-value database. Background technique [0002] Judging from the current research results of real-time data management in integrated power systems, the access to real-time data will be very time-sensitive under the premise of small real-time data. However, when the scale of real-time data continues to increase, or real-time data contains a large amount of semi-structured / unstructured data, many real-time data management methods are difficult to meet the timeliness and scalability required by business scenarios such as real-time monitoring of integrated power systems. [0003] The meaning of the integrated power system in the present invention refers to the ship's integrated power system, including physical domain subsystems such as power generation, transmission, transformat...
