TIK-RVM extended monitoring system for GPU

Upper level - diagnostics expert's AWP / Operator's AWP

At the upper level of the system, there is an industrial workstation with installed SCADA-package and special-purpose modules (diagnostics expert's AWP).

Main screens of the system:

• General mnemonic diagram of the system;
• Mnemonic diagram of the unit;
• Mnemonic diagram of instrumentation;
• Reports;
• Trends;
• Event log;
• Bar charts;
• Review of samples;
• System configurator.

The main mnemonic diagram shows the current state of all units in the shop. When warning or alarm events occur, the indication having several degrees of priority, depending on nature of the fault, appears on the diagram.

When the color indication appears on the general mnemonic diagram, the window with the list of detected defects can be called up. Further recommendations for elimination of the detected defects are displayed in this window too.

The expert system detects the following equipment faults automatically:

• Loosening (defect of fixing);
• Damage of fastening to the foundation and connecting structures (rotor's self-oscillation);
• Defect of coupling;
• Misalignment of shafts;
• Surging and pre-surging condition;
• Stream nonuniformity, stall;
• Hydraulic shock;
• Cavitation;
• Impeller imbalance;
• Defect of blades;
• Defects of the stator;
• Defects of the rotor, rotor runout;
• Phase imbalance (nonlinearity of voltage);
• Rotor imbalance;
• Defects of bearing;
• Misalignment of bearing;
• etc.
  

The bottom part of mnemonic diagram contains navigation buttons. Current state of the unit assemblies, measured parameter values (vibration, temperature, pressure, etc.), and the general operating time are displayed on the mnemonic diagram. Performance indicators that allow to visually determine the time left before the scheduled, medium and major repair are displayed on the mnemonic diagram. Defective assemblies are marked with icons having various colors, depending on nature of the defect.

The progress window for all assemblies appears after pressing "Total operating time".

Event log

The event log describes all events that have occurred with the system. Operator's interface allows sorting the log by various features for easier finding the necessary event.

Reports

The software generates reports in graphical, text, or mixed form automatically.
