In applying knowledge based systems (KBS) to power system operations the solution method was known first and the problem came later. This meant that possible uses for expert systems in power system operations were investigated, without a clear target being defined in the beginning. Due to the rapid prototyping in KBS development, the analysis of the problem for a KBS has been weak. In the switching planning project called EKA, we faced problems in knowledge acquisition and the design. The problems were thought to be avoided by doing the problem analysis more clear and by constructing documents of each phase of it. This study introduces a systematic method for the selection of power system applications for KBSes. The method is based on the assumptions that the role of a KBS is to support existing activities in the power system control center and that the domain can be described with activities. The study also presents a systematic approach to problem analysis containing two phases: - The role specification, in which the environment of the problem domain and the modules within it are analyzed. Based on the analysis, KBS modules are specified. - The KBS structure description, in which the contents of the selected KBS applications are described. The proposed methods are illustrated with the applications for switching planning, restoration, and fault diagnosis.
