OBJECT-ORIENTED ONLINE NETWORK ANALYSIS

Object-oriented programming has gained widespread acceptance, as its a dvantages of flexibility and ease of maintenance have been recognized. In power systems analysis, its use in developing graphical user inter faces and database managers have become quite popular. Object-oriented numerical applications, however, poses an interesting problem because solution algorithms often require the manipulation of abstract mathem atical objects that may not have physical interpretations (e.g., eleme nts of a factorized matrix), and moreover, may be specific to the nume rical algorithm used. This paper presents a method for on-line network analysis using only physically based objects, the same ones that are routinely used in database and user interface applications. It is show n that network analysis, specifically topology processing and power fl ow, is feasible using message passing between physical objects but som e compromise in computation speed is needed to achieve it.
