Functional Description

IC3600AOAM is an Operational Amplifier Circuit Card developed by GE. It is a part of the Mark I and II control system. It functions within this framework by housing operational amplifiers used for signal conditioning and amplification. In turbine control systems, accurate and reliable signal processing is essential for maintaining control over vital parameters such as temperature, pressure, speed, and vibration.

System Features

• The gas turbine and its driven load—whether connected to a generator, compressor, or mechanical equipment—must be thoroughly protected against a wide range of operating conditions that could potentially cause damage or unsafe operation. Like any prime mover system, the protection strategy must be both comprehensive and reliable to ensure uninterrupted performance and system safety.
• These protective measures can generally be divided into two categories. The first includes simple trip signals, which are relatively straightforward and rely on basic devices such as pressure switches or system relays. These devices are designed to respond quickly to predefined fault conditions and trigger an immediate trip or shutdown of the turbine. Examples of such conditions include low lubrication oil pressure, generator differential faults, or high gas compressor discharge pressure. These events are easily detected through binary signals and require minimal processing to initiate corrective action.
• The second category involves the monitoring of more complex operational parameters that demand continuous analysis and nuanced evaluation. These parameters include overspeed, overtemperature, excessive vibration, and flame failure. Unlike simple trip signals, these conditions often require analog signal processing, multiple sensors, threshold logic, and sometimes redundant systems to ensure accurate detection. For instance, overspeed conditions must be managed swiftly to prevent mechanical destruction, while overtemperature situations can lead to thermal fatigue and long-term damage to critical turbine components. Similarly, excessive vibration can indicate developing mechanical faults, and flame instability poses serious safety hazards if not promptly addressed.
