StationCentral – Substation Automation Solution (SAS)


Substation Automation Solution (SAS)

Survalent’s substation automation system, StationCentral, is an advanced SCADA solution that provides a resilient data acquisition engine, information aggregation and processing, and an HMI for utility operations at the substation level.  

The application, fully scalable from single to quad redundancy can be configured in a distributed architecture over multiple substations and offers seamless interoperability between the substation and the control room.  It supports a wide range of open and legacy protocols which run in native mode, so there is no need for an external protocol converter, internal converter, or front-end processor.

With two GUI options available, you have the flexibility to choose the display interface that best meets your substation automation needs – StationCentral VU or SmartVU.



StationCentral offers a wide range of features and optional applications to help you address all your substation automation requirements:

  • Seamless Communications Interoperability
  • Robust Data Acquisition Engine
  • Advanced Supervisory Control
  • Comprehensive Database Editing Capabilities
  • High Performance, Scalability & Availability
  • Flexible Reporting Capabilities
  • Advanced viewer option
  • Reduce Commissioning time with automation tools

Featured Project

Data Acquisition Engine & Gateway

Included with StationCentral is STC Explorer, database editing software to manage all database points, access control, control zones, system parameters, and setup of advanced applications. The database editor provides a graphical, tree-like representation of the complete database and supports easy navigation throughout the database to the desired items to be edited.  The Gateway solution converts protocols from substation devices to standard protocol allowing you to communicate with systems outside of your substation.

The application is capable of accommodating an unlimited quantity of status and control points, analog input points, text points, communication lines, RTUs, IEDs, reports, and graphic symbols. The displays on all workstations are updated and responsive to controls throughout an alarm burst. The application is third-party tested and meets the system availability requirements in accordance with IEEE standards.

StationCentral supports a wide range of protocols including ICCP, MultiSpeak, OPC, SNMP, DNP3, Modbus RTU & TCP, and the family of IEC protocols (IEC 61850 Edition 1 & Edition 2, IEC 60870 101, 104).

StationCentral VU

StationCentral VU features multi-server support that gives users a complete overview of processes and systems being monitored in a single view that is easy to read and navigate.  Display access is based on established user rights, allow a view only screen, supervisor screen or full editing mode.

Available with an enhanced alarm and trend graphs package, users can extract the value of all alarms and display them in a singular, tabular view.


SmartVU offers an enhanced graphics visualization and editing capabilities to manage complex substation assets. It features an intuitive, Windows-based GUI that makes it easy to view, manage, edit, and share all aspects of substation information. The interactive, well-organized & customizable interface provides an in-depth view of all substation assets which greatly enhances the productivity of operators making it possible for them to monitor and maintain precise, local control.

Optional Applications

Survalent Comtrade Viewer, provides operators with a variety of analytics, calculators, and visualization capabilities to conduct data forensics and enable advanced substation automation. Users can examine relay data in tables, graphs, and animations to better understand outages, identify root causes and faults, monitor the health of assets, and prescribe protective maintenance.

IED Wizard, automates the creation of the database for intelligent electronic devices (IEDs), significantly reducing commissioning time by enabling increased productivity and through the elimination of point addressing errors.

Express DB, a powerful visual tool for setup, integration and commissioning work.  Building new databases and maintaining existing ones is dramatically simplified, eliminating the need for use of multiple tools/applications to perform rapid database modifications.
