STCE-NG/STCE-NGS

Remote terminal unit for gas transport networks

STCE-NG is a system developed with the aim of supervising and remote controlling the gas transmission networks. It is a new generation RTU born in the current market context in which operators aim to rationalize and optimize their networks in a sustainable way by serving their industrial and thermoelectric consumers, and urban distribution networks in an increasingly performing way. Based on innovative technologies and characterized by a high level of intelligence, it is able to monitor and intervene on the transportation network system in coordination with the control centers.

STCE-NG is a modular and scalable solution, suitable for network scenarios of various sizes, available in two versions, the Small STCE-NGS model for use in small systems and the Expandable STCE-NGE model for larger nodes. It is able to manage information from and to the plant, allowing quick, timely and flexible communication with the network management centers. It deals with acquiring digital and analog signals, imposing commands and set-points, collecting information from remote devices or local DCS. STCE-NG is configured only remotely for security reasons and monitored locally through an optimized HMI interface, while remotely a web-based management software is available to guarantee simple, timely and effective maintenance interventions. The system also has an advanced synchronization and chronological management capability. The expandable version is synonymous with high availability and robustness thanks to the redundancy of the centralized parts.
