Study Of Substation Automation And Real Time Database

A new integrated substation automation system based on the development and application of computer,communication and net-work is put forward, The main work focuses on the research and realization of this new system.。The structure and features of integrated substation automation system in common use are analyzed. Based on the analysis of the insufficiency of usual integrated substation automation system, a new integrated substation automation system on the basis of the model with four-layer architecture is put forward, and the layered function modularization design idea is applied to developing this system. Furthermore, with the modularization and universal of software and hardware, the configuration of system will be diverse according to the connection ways of primary equipment in different type of substation. The reliability, maintainability and opening of new system are improved. The structure and principle of this system are expounded in the paper.With an aim at the limitation of the relative database system existed in the real-time application of substation automation system, the paper analyses the composition of the real-time database (RTDB) of substation automation system according to the feature of substation Automation. A method of realizing data model and interface using Object-Oriented technology is given. The system structure, distribution mechanism and some system's features is introduced also.The design and realization of different software module is introduced also, with the using of Object-Oriented technology, the software is easy to be updated.Last, a summary and further work of this system are given.
