摘要

This paper describes prudent considerations for applying asynchronous transfer mode (ATM) transmissions, which can provide broadband and multimedia communications as well as flexible, efficient and wide-area networks, to microprocessor-based current differential teleprotection systems. As both functions of current data transmission and simultaneous sampling among remote terminals are required for the telecommunication systems, measures against cell losses and cell delay variations in ATM network elements such as terminal adapters and switches are proposed for the present delay-sensitive teleprotection systems. Allowable system configurations are examined under severe delay constraints in Japan. A new concept of an ATM-native teleprotection system employing time synchronous systems such as GPS is also proposed.
