IEC 61850 Quality Flags and Their Mapping to SCADA Protocols
A quality-first mapping guide covering q attributes, quality-change events, target-protocol limitations, HMI display, control gating and fault injection.
Analog Scaling, Deadbands and Engineering Units for SCADA Measurements
An end-to-end measurement-chain guide for preventing ratio, unit, sign, word-order and duplicated-scaling errors while controlling analog traffic.
Alarm Management for Substations: Priority, Flood Suppression and Rationalization
A practical alarm lifecycle that separates alarms from SOE/status, prioritizes operator action and controls floods without losing forensic evidence.
Cybersecurity Zoning and Conduits for MV Switchgear Automation Networks
A risk-based substation zone-and-conduit design that contains cyber compromise while preserving deterministic protection and essential local control.
Redundant SCADA Servers, Gateways and Communications: Failover Design and Testing
An end-to-end redundancy guide that proves failure-domain independence, safe command ownership, event continuity, failover and controlled failback.
Protocol Conversion and Data Mapping Without Losing Quality Information
A semantic mapping and fault-injection method that prevents values from appearing healthy after protocol conversion has lost quality, time or control meaning.
RTU and Gateway Selection for Multi-Vendor MV Switchgear Projects
A procurement and acceptance framework for multi-vendor RTUs and gateways covering IEC 61850, IEC 104, DNP3, Modbus, sizing and failover.
Sequence-of-Events Resolution and Time Synchronization for Fault Analysis
A rigorous guide separating timestamp resolution from physical-event accuracy and proving event order, time quality, holdover and fault-record correlation.
SCADA Permissives, Interlocks and Blocking: Where Logic Should Reside
A practical cause-and-effect method for placing MV switchgear logic where speed, safety, availability, failure containment and testability require it.
Local, Remote and Supervisory Control Authority: Safe Mode Selection
A practical authority-state design for MV switchgear that prevents competing commands and safely handles mode changes, stale data, failures and maintenance.
