Design And Implementation Of Power System Real-time Database Based On Configuration Software

With quick development in the industry automation fields in China such as power, petroleum and coal, the industry automation has achieved brilliant achievements in China. With decrease of non-renewable resources in the world, energy saving is critical. Energy saving depends on technology innovation and scientific management, but real-time data in industrial production are required in two methods. The real-time data in the industrial production feature high magnitude and quick access. As one professional database system, the industrial real-time database system can collect and store the real-time industrial data sources in real time and has been extensively applied in the information system.For the real-time data in the industrial production, the traditional relational database ignores different real-time requirements in database scheduling and handling decision, so it is not suitable for time-critical application fields. Now the researchers at home and abroad store and display real-time data in industrial production by using memory-based real-time database and configuration software. Now colleges and research organizations at abroad are developing corresponding real-time database for teaching research and scientific research. Now research in this field lags in China, so this paper studies design and implementation of the real-time database system based on the configuration software in power system.This paper studies design and implementation of the real-time database based on the configuration software by analyzing features of industrial real-time data and user requirements for data as well as features of rbal-time databases at abroad. The main research contents are described as follows:1) Design structure of real-time database system based on configuration software and real-time database based on configuration software, including design of real-time database, configuration software, synchronization and backup tools.2) Study real-time data compression algorithm of real-time database based on the configuration software and proposed improved data compression algorithm based on the revolving door data compression algorithm. 3) Study historical data indexing algorithm of real-time database based on configuration software and propose improved B+data indexing algorithm based on B+data indexing algorithm.4) Study data collection interface of real-time database based on the configuration software. The complicated industrial data collection bus should be designed for flexible data collection and can collect real-time industrial data.Finally this paper proposes an application case of the real-time database based on the configuration software at a power plant, which proves that our designed real-time database based on the configuration software can reach our design targets and features technology advance, stability and practicability.
