SAS-Survalent StationCentral


Survalent’s StationCentral, SurvalentOne is an advanced, utility-grade solution that provides a resilient data acquisition engine, information aggregation and processing, and an HMI for utility operations at the substation level. It offers seamless interoperability between the substation and the control room by aggregating and storing real-time data from Intelligent Electronic Devices (IEDs) locally, processing this information, and then sending the resulting data to the control room. As well, the solution is fully scalable from single to quad redundancy and can be configured in a distributed architecture over multiple substations. The graphical user interface (GUI) SmartVU – gives you the flexibility to choose the display interface that best meets your needs. Quick to deploy, easy to manage, and highly scalable, StationCentral protects your investment in mission-critical substations.

Product details
  •  Seamless Communications Interoperability
    StationCentral supports a wide range of open and legacy protocols including ICCP, MultiSpeak, OPC, SNMP, DNP3, Modbus RTU & TCP, and the family of IEC protocols (IEC 61850 Edition 2, IEC 60870-5-101/104). All protocols run in native mode, so there is no need for an external protocol converter, internal converter, or front-end processor.
  • Robust Data Acquisition Engine
    StationCentral data exchange servers supports multiple status changes from control commands, and monitors analog and digital values such as volts, amps, watts and VARs at each substation. Values can be displayed on the StationCentral VU or SmartVU GUI, and with alarm limit checking and historical storage at definable interval and retention periods. It can also accumulate kilowatt-hour pulses from pulse initiators at each substation, freeze counts by RTU on a user definable interval, and convert the counts into interval and hourly deltas.
  • Advanced Supervisory Control
    StationCentral uses a Select Before Operate procedure that is fully compliant with IEEE standards. Secure handshaking with the RTU/IED is required before any controls are executed or an alarm is raised. An optional multiple status change validation feature is available to handle cases where a control causes multiple status changes to occur. Operators can inhibit control of devices by means of a secure, multi-level tagging feature, giving them the ability to apply up to eight tags to each point.  Alarms and operational events are continuously synchronized in real-time to the standby host server. StationCentral is able to handle a minimum of 1,000 alarms or events per second per operator console, with 10 alarm priority levels. As well, StationCentral can be partitioned into 128 areas or zones of responsibility. The user has the ability to assign any combination of the 128 zones to each telemetered or calculated database point and/or
    to each login account. An operator is able to manipulate only those points whose zones overlap those of the login account. Each user account is assigned a set of user rights that determines the actions that the user may take, providing individual control over various operating and editing functions. The system can handle an unlimited number of user accounts with their corresponding user rights and privileges.
  • Comprehensive Database Editing Capabilities
    StationCentral includes Explorer, database editing software to manage all database points, access control, control zones, system parameters, and setup of advanced applications. It also includes station clones and point modeling features. 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. All changes and updates of the database are completed and validated while the system is in online operation. Real-time system operation is not interrupted or disturbed by the database editing and maintenance process.
  • Flexible Reporting Capabilities
    StationCentral supports a report generation capability that allows the user a high level of flexibility in defining, formatting, and scheduling on-demand and periodic reports. The Report Editor allows the user to definable reports by specifying a database table, a set of desired data fields and the selection criteria for retrieving records from the database table. Reports can be exported to a spreadsheet or PDF
  • SmartVU
    SmartVU is available for utilities that need 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
