An object-oriented approach for implementing power system restoration package

Due to many unforeseen circumstances that could happen in today's bulk power systems, there is a possibility of a system wide outage. In order to provide aids to power system dispatchers following a complete collapse of the power system, a prototype expert system software package has been developed. Through an interactive and friendly graphic interface, the package suggests a guideline for the dispatcher to restore the power system. With the aim of improving ease of maintenance, object-oriented techniques were adopted to implement the package. The development of the software involved three stages: (1) object oriented analysis; (2) object oriented design; and (3) integration and testing. In this paper, the structure and the development procedure of the prototype system are presented.
