Functional Description

IC3600SOSF1E is a LVDT Oscillator Card developed by GE. It is a part of Mark I and II control system. It is designed to provide the excitation signal required to operate LVDT-based position sensors, which are commonly used for accurate measurement of valve positions and other linear displacements in turbine applications.

Functionality and Role in the Control System

• In the Mark I and II control systems, LVDTs are essential for monitoring the position of critical turbine components such as gas control valves, fuel valves, and IGVs (Inlet Guide Vanes). The oscillator card generates a stable AC excitation signal—typically in the range of several kilohertz—that powers the LVDT sensors. The resulting output from the LVDTs is then processed and interpreted by other control components to ensure accurate position feedback and precise control.
• The Speedtronic Mark I and II systems were designed to offer dependable control and protection for gas turbines, incorporating features that support a wide range of operational scenarios. The card contributes to this by ensuring precise and continuous position sensing, which is essential for real-time control decisions.

System Features

• Multi-Point Annunciator System: The control system is equipped with a multi-point annunciator to detect, display, and alarm abnormal conditions during startup and normal turbine operation. This allows for proactive fault management and system diagnostics.
• First-Out Flashing Alarm: A first-out flashing feature highlights the initial fault detected by the system. This aids operators in troubleshooting by identifying the root cause of shutdowns or alarms quickly and effectively.
• Modular and Customizable Design: The Mark I and II platforms were designed to be flexible and adaptable, supporting a variety of application-specific requirements. Common options include:
  • Multi-fuel configurations (e.g., gas and liquid fuel)
  • Black start capability
  • Remote operation
  • Deadload pickup
  • Variable airflow control for heat recovery applications
• Emissions Control Compatibility: For systems employing steam or water injection to reduce NOx emissions, the control system can be configured to include monitoring and recording tools for environmental compliance, including meeting EPA regulatory requirements.
• Advanced Operational Options: Depending on site needs, Mark I and II systems can support a wide range of features such as Fast start and fast load functionality, Automatic load control, Power augmentation methods, and Inlet heating for cold-weather performance.
