RTU iRTU according to Terna specification

Terna, in its "Code for transmission, dispatching, development, and network security," has established that the owners of plants whose operation influences the functioning of the National Electricity System must make all necessary information available for the purposes of supervision and control, remote regulation and disconnection, and remote monitoring of the plant.

To enable the correct performance of monitoring and control activities of the Network, Terna has determined that measures and signals must be made available to ensure the observability of every plant and the essential functions of electrical system management for: 

The information must be made available at Terna's Access Points (PA) in a manner fully compatible with the Terna Control System, as prescribed by annex A.13 of the Network Code. The data to be made available are both digital and analogue and depend on the number and type of systems connected to the NTG and include the states of the switching devices and the electrical measurements associated with the HV/MV system.The acquired data must be transmitted to the Terna Control System over a dedicated network with the IEC 60870-5-104 protocol.

Thanks to collaboration with its subsidiary IGRID T&D, Thytronic provides RTU (Remote Terminal Unit) systems compliant with the Terna specification (redundant CPUs) capable of acquiring the required signals both in wired (digital input, analogue input) and serial modes (RS485/422, Ethernet interfaces) using the most widespread industrial protocols:

The Thytronic RTU system can be perfectly integrated with the communication system (TLC) installed in the plant and managed by Terna, in particular, the CPU in a redundant configuration makes available respectively:

Our RTUs also integrate the following functionality:

The system can be supplied mounted in a RACK cabinet complete with accessories and configured as per Terna specification.
