Substation Comprehensive Automation System Software Engineering & Realization

Electric power network automatization is faced with the information technology full of vitality and the management mechanism of the electric power network, and that substation comprehensive automation system is an important element of electric power network. So it requires high characters of reliability, real-time, simultaneity and distribution of the automation system.The paper bases on the practical project . It is researched by means of design and empolder in laboratory and lots of locale debugging . The main tasks that have been finished are list as follows:1) It analyzes the functions and characteristics of the 110KV substation comprehensive automation system and designs the hardware structure > scheme blueprint through it' s requirement.2) It overcomes the shortcomings of the method with configuration and the limitation of ecumenical way to realize SCADA. It puts forward the ways and means of empoldering with Component Object Model. It also designs and realizes substation comprehensive automation system frame and software model which not only have plenty of interfaces including three-layers applied mode and open data, but also have nothing to do with quadratic equipments.3) Different objects are distilled from three layers applied mode, and the objects' configurations,dynamic and abstract.4) CIS system is realized by means of objected-orient and module. It can make wiring diagram and transfer interfaces.5) Interrelated parts are realized succeedly with COM. The stability and the currency of the system software are enhanced.6) The whole software of the substation comprehensive automation system is realized with the rapid-developed language Visual Basic which is object-oriented.The work has been used well in practice, which builds up basement and makes some experience for class databases of substation comprehensive automation system software. The contents in the paper have a good use for reference to exploiture 220KV or 500KV Substation comprehensive automation system, even higher Voltage.
