The electrical distribution architecture has a vital impact on performance of the installed system throughout its lifecycle. The design of a power system like an hospital has to be comprehensive in regard to the system traditional design configuration aspect as well as its operational safety aspect, such as management and maintenance.

The architecture of an installation involves the configuration, the choice of power sources (utility and alternate power source) the definition of different distribution levels and the choice of equipment.

To enhance the integrity of power system analysis and operation, the design could adopt the cut and 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.

Abstract
The electrical distribution architecture has a vital impact on performance of the installed system throughout its lifecycle. The design of a power system like an hospital has to be comprehensive in regard to the system traditional design configuration aspect as well as its operational safety aspect, such as management and maintenance. The comprehensive design has to survey and define both aspects during the different design phases and during the overall operational life cycle of the system. The architecture of an installation involves the configuration, the choice of power sources (utility and alternate power source) the definition of different distribution levels and the choice of equipment. Each node presents a kit of instructions as a logic gene describing a complete and reversible evolution of the component switching means from a opening status to a closing one. Previous papers have introduced a language-program for analyzing and transcribing the instructions of safety procedures for each working zone WZ and of integrity procedures for each sources node versus the loss of service continuity (Parise program). This paper discusses 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 and 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
