An electrical distribution architecture has a vital impact on the performance of an installed system throughout its lifecycle. The architecture of an installation involves the configuration, the choice of power sources (utility and alternate power source), the definition of the different distribution levels, and the choice of equipment. Previous papers have introduced a language program for analyzing and transcribing the instructions of the safety procedures for each working zone and of the integrity procedures for each source node versus the loss of service continuity (the Parise program). Each node presents a kit of instructions as a logic gene, describing a complete and reversible evolution of the component switching means from an opening status to a closing one. This paper deals with the architecture of a power system and the combination of procedures in the operation on a nodes system. It will show the impact of the architecture on the comprehensive procedures for a complex system. To enhance the integrity of power system analysis and operation, the design could adopt the cut&tie rule, introducing ring configuration and floating nodes. The suggested advanced approach assists in the elaboration of the procedures for switching from one set or configuration of a power system to another and will help the training of operators in defining the instructions to be used in the development and the operating of each power system.
