Distribution Management System (DMS) applications can be used to track actual railway network conditions or test different scenarios in the safety of a simulated study-mode environment. The DMS helps the dispatcher see beyond the substations with the inclusion of a network model, a topology processor and a lightning-fast 3-phase, unbalanced load flow.

Telvent’s DMS is a suite of realtime and study-mode applications designed to support and enhance online distribution SCADA operations. The applications are seamlessly integrated with the OASyS SCADA system to provide a consistent user interface and also make the applications accessible from any operator or engineering workstation within the enterprise.

The Traction Energy Remote Control and Management System allows for the supervision and control of traction electric installations from one or several locations. Centralized management improves the availability indices of the installations, the outage response time, and the alternative solutions for reducing personnel requirements.

The system is based on Telvent’s OASyS SCADA system and incorporates a combination of Telvent’s experience, its know-how, and state-of-the-art open system architectures.

With the purpose of adding value to the information obtained from the remote control acquisition systems, Telvent has developed the following applications, which are seamlessly integrated with the SCADA system:

• Exploitation sequences reconstruction
• Installations remote monitoring via Web
• Energy metering and quality analysis
• Outage management system

Telvent’s distributed control system, comprised of a control cabinet, remote actuator and voltage detector is designed to increase the security, efficiency and maintainability of catenary systems, guaranteeing the security of the installations and their coordination with associated remote control systems.

This solution has been developed for the remote control of both catenary circuit breakers and railway auxiliary feed systems. In either case, the traditional centralized configuration solution is available.

Telvent provides integrated protection and control systems covering all voltage level substations using a unique approach that combines its own products, such as the Saitel and subCAT families of Remote Intelligent Units, and third-party products. This approach is possible thanks to Telvent’s extensive integration experience, proven expertise and strategic alliances with industry providers of protective relays, meter devices, and remote control equipment.

The Saitel and subCAT family, developed by Telvent, provides robust, reliable, open, extensible, flexible control platforms capable of handling the monitoring and local control of traction electric substations, in direct current (3.3 kV y 750 V) or alternate current (25 kV), thanks to its rich library of standard and legacy communication protocols, advanced software tools, extensive modularity and high processing capability.

Telvent owns a range of Acquisition Remote Terminal Units for integrating information coming from different locations along the railway line via its own or other third-party Remote Control Centers.

The solutions based on subCAT and Saitel technology guarantee this functionality in railway operative conditions as well as the modularity, expansion capability, reliability and interoperability of the system for substations, catenary distributed control systems and third-party solutions. The following are some examples of these data acquisition units’ components:

• Switching Centers
• Tunnel lighting cabins
• Switch heater
• Tunnel equipment
