What is RETROFITTING?
Adding a component or accessory to a product that did not have it when it was manufactured.
This can be answered by considering the operating plant costs for:
- Frequent maintenance and re-calibration
- The level of manual intervention to operate
- Unreliable equipment breakdown
- Non scheduled shut down
- Difficult to diagnose situations causing extended outages.
Experience has shown that failures are mainly due to:
In other words, the core engine is robust and reliable; it is the control and instrumentation equipment that causes the majority of failures.
What can TCL retrofit?
When considering a retrofit always try and move as many control functions from hydro-mechanical equipment to software, electronic or electrical control. This will always improve reliability.
A typical scope of a controls system retrofit might include:
- Plant sensors including:
- Switches replaced with transmitters (pressure and temperature)
- Control functions including:
- Temp, Press Monitor
- Vibration monitor
- Overspeed Trip
- Emergency Shutdown
- AVR, Gen Protection
- Load Management
- Operator Interface
- Event Recorder
- Remote Control
- Plant driven devices such as:
- Fuel control valves, gas/liquid
- MCC Starters
