Scada Open System Model Based On Uml

SCADA is widely used in many power companies.It is the very important technology to support operation of power system.It is also the basic for dispatch automation.With the development of technology, more and more new software developing methods are emerging.With these methods we can build a new SCADA which is conform to the international standards, more flexible,more open ,more easy to integrate with other systems.This thesis discuss SCADA's analysis and design .Firstly,it deeply analyses the system,then builds a general designing model of the system conform to the IEC61970,and the last it gives a detailed model of the Event and Alarm subsystem.In the process of the develop,two software engineering technologies , UML and RUP mainly support the develop, they present a new kind of advanced software developing idea and method.
