Power systems information delivering system using Internet technology

Computer network technology and distributed information processing technology have been developing rapidly. In the meantime, deregulation is starting and will be spreading in the electric power industry in Japan. Consequently, customers request low cost power supply and high quality services from the power suppliers. Corresponding to these requirements caused by deregulation, the authors developed a prototype power systems information delivering system supplying useful power systems information such as power failures. The prototype system was developed based on SCOPE (system configuration of power control system) architecture that we had already proposed. SCOPE architecture assures flexibility and scalability for power systems. The prototype system consists of an application layer based on a Web browser, an information model layer which reflects the power systems behavior and a distributed object management layer using CORBA and OS/Network layer. In this paper, we introduce the concept, functions, implementation of the prototype system and its evaluation results.
