What is Why is frequent switching on/off harmful??

During every cold start, increased mechanical stresses occur due to thermal expansion and insufficient pre-lubrication; more than 3 starts/day are considered critical — sufficiently large buffer tanks and optimised gas level control reduce starts.

What the AI reads from these values

What the AI reads
  • Increase in cooling water temperature as an indicator for thermal load cycles
  • Deviation from the setpoint due to unstable gas level control
  • Increased wear rate due to insufficient lubrication during cold starts
  • Degradation of heat exchanger efficiency due to thermal stresses
Scenario

Monitored: continuous

The scenario: a gradual drop in oil pressure or a drifting temperature remains below the alarm threshold until the emergency shutdown occurs — at the worst possible moment. The AI: detects the deviation from normal operation early and reports it before the protection trips. It identifies the trend before the limit value is reached.

Why this matters

Reduced start cycles minimise material fatigue and significantly lower maintenance costs. Stable operation reduces mechanical wear on critical components. This extends the MTBF (Mean Time Between Failure) and ensures the long-term availability of the plant. electrical power (kW) · supplied gas power (kW) → — % elec. efficiency Calculation: electrical power ÷ gas power × 100
