This chapter presents a state-of-the-art on fragility models for the components of Electric Power Networks (EPNs) available in the technical literature. First, the main characteristics of an electric power network and its taxonomy are introduced. Then, the main recent works on fragility functions of electric components are listed, and details are provided for a few selected ones. In the last section, the fragility curves which are most suited for use in the European context are selected, with the indication of parameters and relevant information. The selection has been based both on the data supporting the models and on the adopted systemic approach to the simulation of EPN within the SYNER-G general methodology for infrastructural systems’ vulnerability assessment. The latter adopts a capacitive, detailed flow-based modelling with short-circuits propagation over the network and requires the modelling of the substation internal logic.

Abstract
This chapter presents a state-of-the-art on fragility models for the components of Electric Power Networks (EPNs) available in the technical literature. First, the main characteristics of an electric power network and its taxonomy are introduced. Then, the main recent works on fragility functions of electric components are listed, and details are provided for a few selected ones. In the last section, the fragility curves which are most suited for use in the European context are selected, with the indication of parameters and relevant information. The selection has been based both on the data supporting the models and on the adopted systemic approach to the simulation of EPN within the SYNER-G general methodology for infrastructural systems’ vulnerability assessment. The latter adopts a capacitive, detailed flow-based modelling with short-circuits propagation over the network and requires the modelling of the substation internal logic.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
