Functional Description

IC3600AVIA1 is a Voltage Isolator PC Board developed by GE. It is a part of the Mark I and II control system.The primary function of the board is to provide voltage isolation between different parts of the control circuitry. Voltage isolation is a critical function in turbine control systems, as it ensures that high-voltage signals or noise from one section of the system do not interfere with or damage sensitive control logic components. By electrically isolating signal paths, this board helps prevent ground loops, reduces the risk of electrical interference, and enhances overall system stability.

Design Features

• The control system incorporates built-in features specifically designed to support both the gas turbine’s operation and the operator’s control capabilities. Among these features is the Minimum VCE System, which plays a crucial role during fuel cutback scenarios. This system ensures that the turbine receives a minimum, controlled level of fuel flow referred to as Valve Control Equivalent (VCE) to prevent flame-out conditions. By maintaining this minimum fuel supply during transitions or reductions in load, the system safeguards combustion stability and prevents turbine shutdowns due to loss of flame.
• Another notable feature is the Manual VCE Control, which provides operators or start-up technicians with the ability to directly manage the VCE during initial start-up or troubleshooting procedures. This manual control function offers greater flexibility during sensitive operational phases, such as ignition or load ramp-up, allowing for hands-on management of fuel delivery and turbine behavior.
• Importantly, even when the Manual VCE mode is engaged, the system’s protective logic remains active. The manual input is still subject to the minimum value gate, a mechanism that continuously monitors and limits fuel flow based on critical parameters such as turbine speed and temperature. This ensures that the turbine is protected from overspeed or overheating, regardless of manual intervention, by automatically reducing fuel if necessary.

FREQUENTLY ASKED QUESTIONS

What is IC3600AVIA1?
It is a Voltage Isolator PC Board developed by GE.

Why is preventing flame-out important in gas turbines?
Flame-out refers to the loss of combustion within the turbine, which can cause operational interruptions, mechanical stress, and potential safety risks. Preventing flame-out is essential to ensure continuous, reliable, and safe turbine operation.

What is Manual VCE Control and when is it used?
Manual VCE Control allows an operator or technician to manually adjust the turbine's fuel flow during startup or troubleshooting. It gives direct control over the VCE, enabling precise adjustments during sensitive operational phases such as ignition or loading.
