The relevance of the architecture of electrical power systems in hospitals: The service continuity safety by design

The power system architecture of hospitals supports by design an enhanced electrical behavior also adequate to the better withstand to external forces, if actual, as earthquake, fire, flood, applying a “Darwinian” approach. The architecture of the power system, supported by supervision control systems and a business continuity management (BCM), must guarantee operational performances that preserve the global service continuity such as: selectivity of faults and immunity to interferences among the system areas; easy maintainability of the system and its parts; flexibility and expandability. The paper deals with sample cases of systems in complexes of buildings applying the micro approach to satisfy hospital requirements and medical quality performances.
