ABSTRACT
In this paper, the problems exposed by the third generation of SCADA (Supervisory Control And Data Acquisition) based on the POSIX (Portable Operating System Interface of Unix) standards for UNIX systems are analyzed. Then it makes a brief description of the advantages of the new generation power SCADA system based on the J2EE (Java 2 Platform, Enterprise Edition) framework by using open architecture and object-oriented technologies. The integration bus characterized by standardization and component-based is one the key technologies in implementing this new SCADA system which is based on IEC (International Electrical Commission) 61970. By replacing tightly-coupled CORBA (Common Object Request Broker Architecture) to realize CIS (Component Interface Specification) interfaces, Web services components provide more standard and open interfaces for the information sharing and interoperability among application systems of power enterprises. CIM (Common Information Model) is used to describe power system resources and establish models for the database and SVG (Scalable Vector Graphics) elements. As the graphic expression method of the system, SVG with a combination of CIM achieves integrative graphic model library. The use of advanced design patterns also contributes the scalability to some extent and makes the system much more powerful in dealing with constant changes.
