European Definitions

EU JRC
Reliability HDVC is a measure of the capability of the HVDC link to transmit power above some minimum defined value at any point in time under normal operating conditions. [1]

Reliability is normally expressed as the number of times in one year the scheme is incapable of transmitting power above a minimum defined value. This inability to transmit above a defined power level is termed Forced Outage Rate (F.O.R.).

International defintions

IAEA

Reliability: the ability of an item to perform a required function under given conditions for a given time interval. [2]


National Definitions

Brazil

Confiabilidade:
1. Capacidade de desempenho de componentes, de equipamentos ou sistemas, em função de padrões preestabelecidos.
2. Probabilidade de um equipamento ou sistema desempenhar correta e satisfatoriamente suas funções específicas, por um período de tempo determinado, sob um conjunto estabelecido de condições de operações. É uma medida de qualidade e depende da variável tempo. [3]

Reliability: The ability of an item to perform a required function under stated conditions for a specified period of time. [7]


Reliability: The probability that a functional unit will perform its required function for a specified interval under stated conditions. [7]


Reliability: The continuous availability of communication services to the general public, and emergency response activities in particular, during normal operating conditions and under emergency circumstances with minimal disruption. [7]

Affidabilità: La combinazione di due condizioni: (1) Disponibilità: idoneità a far fronte staticamente ed in ogni istante alle richieste globali di potenza ed energia elettrica dei clienti nei punti di connessione, tenendo in conto i fuori servizi programmati e forzati dei componenti del sistema elettrico, (2) Sicurezza: idoneità ad affrontare i disturbi improvvisi come cortocircuiti o perdita forzata di componenti del sistema elettrico. Tale aspetto considera quindi proprio gli effetti delle transizioni non affrontate con il precedente criterio. [8]


Japan

信頼性: 定の期間、宣言された条件下において要求された機能を行うシステムの能力.
