SIRIUS SCADA system enables the operator to monitor  and control a hydro-power plant by integrating with Governor controllers, protection equipment, energy meters, temperature scanners etc. Generating Units are auto-started through a sequence which completes with auto-synchronization of the unit with the grid. A comprehensive protection system ensures  the safety of  Generators, Transformers and Lines. A tripping in the plant is reported in SCADA system for immediate action and analysis. Events resulting from a tripping, known as Sequence of events (SOE), are time stamped of millisecond resolution for ensuring correct chronology which is essential for trip analysis. SCADA system keeps track of total energy imported/exported to the grid. Reports on total power production, plant’s electrical/mechanical parameters, CB trips, line trips are generated.

SIRIUS can monitor and control power transmission lines, including EHV, HVAC, HVDC systems. Sequence of events recording, monitoring of analog parameters, generation of log sheets, etc. can be performed. Further, different makes/models of SERs, Disturbance recorders can be integrated into SIRIUS for a single point of monitoring/control access. SIRIUS can also act as a slave /master (Inter-Center Communication) for exchange of substation parameters in a hierarchical topology. With support for both proprietary and standard protocols (IEC 870-5, IEC 61850) SIRIUS can be employed in both old and modern substations.

Power distribution substation consist of a number of incoming and outgoing feeders, transformers for stepping up/down the voltage levels, equipment for reactive power control, circuit breakers and isolators etc. SIRIUS based Substation SCADA system performs the following functions:

Status monitoring of all incoming and outgoing feeder CBs  Monitoring of all electrical parameters and declaration of alarms Control operations  Keeping track of energy import/exports  Sequence of Events (SOE) for trip analysis. Time stamping at 1 ms resolution  Interface to protection  system  Comprehensive sets of reports including daily log sheets, voltage profile, CB trip time,
Line trip report, disturbance report etc.  Husky RTU has been approved by Northern Region Power Committee for deployment in the Grid Substations.

SSS has been approved by Indian Railways through RDSO for supply of SCADA system for traction power monitoring and control in its electrified network. SIRIUS SCADA along with its latest generation of Husky RTUs have been deployed on various sections throughout the country. This system is used for remote monitoring and control of traction power distribution in Railway networks. System also helps in day-to-day maintenance of the traction power network by facilitating power block from the remote control room in the sections where maintenance work is to be carried-out. The system also helps in fast restoration of power in cases of failures such as transformer break down, by allowing extension of power from adjacent section. Automatic Fault Localization function helps in locating and isolating the faulty sections. The system also monitors maximum demand, energy consumption and control of power factor.

Cross-Country Pipelines are used to transport crude oil, refined products and gas. SIRIUS SCADA system is installed for monitoring and control of pipeline & brings into its scope Pump Stations, Block Valve Stations, Tap-off-points and Terminal stations set up along the pipeline. SIRIUS SCADA system along with Husky RTUs are installed at each pump station, tap-of-point and terminal station for local monitoring and control of equipment. SCADA system installed at a central location called Master Control Station (MCS) remotely controls various equipment for each station so as to control the flow of oil/gas to terminal locations, as required to meet the daily delivery targets. MCS acquires hydraulic data (Pressure & Flow) and the physical data (Product Densities, Temperatures etc)available from various stations along the pipeline. This data is utilized by SSS’s Pipeline Management System for a variety of applications, e.g., Leak detection and location, pig tracking, batch tracking, pipeline simulation etc.
