Relay protection monitoring, diagnostics and operation assessment system



About system

RTSoft Relay protection monitoring, diagnostics and operation assessment system is a comprehensive solution for automating the workflow of protection engineers who service relay protection devices (IEDs) in power utilities, oil & gas and industrial enterprises.
Download our detailed product presentation, which includes a brief customer reference, to explore features, architecture, and the benefits of implementation. For an in-depth technical overview, see our CIGRE Session paper on PMD System implementation.
Real-time remote monitoring and diagnostics of protection IEDs:
  • Timely detection and notification of malfunctions, with proactive diagnostics to identify hidden failures
  • Automatic verification of IEDs settings against reference values
  • Support of condition-based maintenance strategies
Fault event analysis in HV & MV electrical grids, with assessment of protection operations correctness:
  • Automatic data collection from IEDs & SCADA
  • Notifications about fault events and protection operations
  • In-depth analysis of fault events using real-time signals, event logs, and fault records
  • Automated generation of reports with analysis results
Information and data exchange about protection devices state and fault events analysis between transmission & distribution control centers, power generation companies and grid operators

Benefits

Reliability
Reduces incorrect protection operations and enhances grid reliability through timely detection of hidden protection IED malfunctions.
Time-saving
Minimizes the time required to analyze fault events and supports objective decision-making in protection operations assessment.
Prevention
Decreases the number of grid shutdowns caused by relay protection malfunctions or misoperations.
Cost-effectiveness
Condition-based maintenance of protection IEDs helps optimize operating costs by reducing unnecessary preventive maintenance activities.
