The results presented here reflect work, extending over several years, to identify features underlying restoration processes that are common to almost all utilities and that can serve as guides for preparing and evaluating restoration plans, for developing expert system programs that will be widely useful, and ultimately for improving the effectiveness of restoration practices. Generality is achieved by identifying constituent elements of the process, namely a "target system", "restoration building blocks (RBBs)", "generic restoration actions (GRAs)", and process constraints, and the factors that distinguish among three clearly demarcated stages. This distillation of the constituent elements of the restoration process provides a basis for development of a comprehensive, knowledge-based restoration expert system appropriate to a broad spectrum of power system utilities.< >
