Substation SCADA & Electrical Control and Monitoring Systems

What this covers

• IEC 61850 MMS client integration with Siemens SIPROTEC, SEL, Schneider MiCOM and ABB Relion protection relays.
• Modbus TCP and RTU polling of multifunction power meters (Siemens PAC, Schneider PM series), battery chargers, UPS units and transformer temperature controllers.
• Profinet and OPC UA integration upstream to plant DCS and building management systems.
• Animated single-line mimic — breaker state (closed, open, tripped, racked out, earth switch closed), voltage, active and reactive power, and power factor.
• Sequence of Events logging at millisecond resolution with SNTP time synchronisation, so a cascading trip can be reconstructed in order.
• Power quality reporting — THD monitoring, load duration trends and energy consumption logs.
• Network architecture — segmentation, redundancy and the communication point schedule.

What you receive

• WinCC Unified, WinCC V8 or WinCC OA project, as the site standard requires
• Tag address map covering Modbus registers and IEC 61850 data objects
• Network architecture drawing and I/O communication point schedule
• Alarm and event configuration with priority classification
• FAT test script and witnessed test record

Standards and references

Communications are engineered to IEC 61850 for substation data and the relevant Modbus and Profinet specifications, with network segmentation reviewed against IEC 62443 principles for industrial control system security.
