Power Network Control Using Object- Oriented Term-Rewriting
Adam Steele · 2001
In this paper, we describe the use of the expert system shell CLIPS to define the network model in the Distribution Management System (DMS) for the Indonesian State Power system (PLN). Although, the DMS is implemented by a mixed CLIPS/C++ system, the rules defining the behavior of the system are developed using the framework of Object-Oriented Term-Rewriting (OOTR) to guarantee the asynchronous characteristics of the program’s execution. Another advantage of using OOTR is that we can describe both the power propagation in the network, and the alarm conditions which have to be monitored in a uniform fashion. We discuss the performance of the system, and the general approach of using OOTR as part of a rapidprototyping methodology for power networks and other reactive systems.
