Functional Description

IC3600TILA1B is an Inverter Limit Board manufactured by GE Fanuc. It is a part of Mark I and II control systems. The board regulates and limits the operation of the inverter section within the turbine control framework. It ensures that voltage, current, and frequency outputs remain within specified safety limits, protecting downstream components and maintaining stable system performance.

The Sequential System in Turbine Control

• The sequential system plays a crucial role in the automatic control of turbine operations, including startup, loading, and shutdown. Its primary function is to ensure that these processes occur in a logical and safe sequence. Beyond managing the turbine’s core functions, the system also activates various auxiliary systems, such as auxiliary lubrication pumps and fuel forwarding systems—critical for safe and efficient turbine operation.
• Designed with a fail-safe philosophy, the system ensures that in the event of a fault or malfunction that could endanger operation, the turbine will be automatically and safely shut down. This approach helps protect the equipment and maintain operational safety. The system’s high reliability is a result of the careful selection and engineering of both electronic and hydromechanical components.

Components of the Sequential System

The sequential system consists of a variety of input and output devices:

• Input Devices: These include pressure switches, temperature switches, and other sensors that detect operational conditions.
• Output Devices: Examples include solenoid valves, motor starters, and actuators, which carry out control commands.
• The internal logic—such as timers, speed relays, and sequencing functions—is implemented using solid-state electronic devices, enhancing reliability and response time.

Automatic Sequence of Operation

• Activates the auxiliary systems, such as lube oil pumps and fuel forwarding pumps.
• Engages the clutch to connect the turbine to the driven load (if applicable).
• Cranks the unit, rotating the turbine shaft to bring it up to firing speed.
• Turns on fuel and sets the proper amount for firing.
• Ignites the fuel and detects flame presence to confirm successful ignition.
• Sets up the warm-up cycle, managing warm-up duration and fuel flow.
• Determines key speed points, used to monitor and control startup progression.
• Detects completion of the startup sequence, ensuring all conditions are met.
• Initiates synchronizing to match the generator's output with the grid.
• Closes the generator breaker, connecting the unit to the electrical load.
• Loads the unit, gradually increasing output to the desired power level.
