We are considering the integration of power system control and teleprotection signal transmission in ATM networks. To transmit teleprotection signals in ATM networks, we need ATM switching systems and terminal adapters which convert teleprotection signals into ATM cells and vice versa. In ATM networks we have to reduce delay times and delay variations of these signals.
This paper describes requirements of an ATM switching system and a terminal adapter to transmit teleprotection signals. The ATM switching system is required a delay priority control and a good shaping method. While a commercial terminal adapter sometimes is not satisfied transmission requirements of digital current diffirential teleprotection signals, we proposed configuration of a terminal adapter to be satisfied these requirements. We examined the number of repeaters in ATM networks when we transmit these signals applying above ATM switching system and a proposed terminal adapter.
