Plant Health Sensor – ADEX Control System Optimization Programs

Plant Health Sensor - ADEX

The ADEX Plant Health Sensor extends the features of existing Control System Optimizers and adds expert analysis on data to locate potential problems.

It is a tool to diagnosis non-obvious of elements of the Plant

  • Failures
  • Malfunctioning’s
  • Faults
  • Performance loses

As results, performance is increased once again, and plant availability is improved.

Power Plant Monitoring & Optmization Control System

ADEX Controllers could be used as non-intrusive sensors which listen to other elements. The ADEX Control System enables the proactive detection of problems in both critical variables under control and other indirect variables, e.g.:

  • Mechanical stress failures, temperature trips, corrosion, ashes, etc.
  • Malfunctioning of valves, meters, sensors, etc.

The Core of the Health Sensor: Stabilization of process outcome.

  • LEFT (with conventional control): If outcome is not stable enough even the best Big Data system cannot extract conclusions from changing behaviors on I/O.
  • RIGHT (with ADEX): But if it is stable, changes on I/O could be analyzed and warnings are extracted easily.

“We realized that a 30€ filter costed us 30K€ only in fuel plus the thermal stress”. Head of I&C at 1158 MW coal-fired power plant.

  • Health Sensor detected a malfunction on an attemperator spray valve: unexpected delay only when opening.
  • Plant Operator found a failure on vent valve filter, following Sensor indications.
  • Due to ADEX Control System the Plant was performing properly, so no warning at Dispatch, but working forced.
