The Study Of Power System SCADA Software Based On Multi-Platform

Electrical automation system applies control technology, computer information technology and communication technology. It can do all kinds of operation automatically through computer software and hardware instead of manual work. It is a system that raises power system operation and management standard. Monitor and control systems of substation/hydropower station belong to upper computer part in the electrical automation system. Their software design and program running have close relationship to operation system of upper computer, which are various in the existing electrical automation system application. Furthermore, the situation of the various operation systems coexisting in the electrical automation system will be lasting for a long time in the future, so the development of Configuration Software which is compatible with multi-operation system is urgent affairs.The dissertation begins with structure and functionalities of the supervisor and control system, followed by the discussing of emphases and difficulties of the implementation of multi-operation system Configuration Software. And then the dissertation compares the difference of the platforms and the capabilities of developing tools. Based on this, a solution scheme fitting the requests of multi-operation system is given. This dissertation shows a means to achieve the compatibility and the capability of the Configuration Software to be used on different operation system platforms. To achieve that, it is introduced in the dissertation that the using of novel program developing tool package Qt into the design and implement of the Configuration Software of electrical automation system, and on the base of that, how to conquer the incompatibility between different operation system in the data base accessing and the development of graphical user interfaces is analyzed. On the base of technique analysis, a set of SCADA monitor and control system is developed and tested in the different operation system platform. The monitor and control system consists of real-time data base, drawing package, Human Machine Interface program, data communication part and data acquisition part, manage tools. As a supply for the Client-Server mode, it is also introduced briefly in this dissertation that the problem and technique to which the electrical system Configuration Software based on browser-server mode would come down. A method of adaptation of Flash technology to design Web application software is put forward in the dissertation.
