Functional Description
IC3600SDCA1A is a PCB Board developed by GE. It is a part of Mark I and II control system. The board offers signal processing capabilities for managing inputs and outputs critical to safe and efficient turbine operation. The board's function could involve data conditioning, relay driving, sequencing logic, and system protection.
Protective Systems of Mark I and II
- High reliability in the turbine's protective system is achieved by incorporating a significant degree of redundancy throughout the design. Redundancy ensures that even if one component or pathway fails, backup systems are immediately available to maintain protection and prevent damage to the turbine.
- One key aspect of this redundancy is the use of at least two independent methods for shutting off fuel to the turbine in the event of a fault or unsafe operating condition. These independent fuel shut-off mechanisms guarantee that the turbine can be safely brought to a halt, even if one method becomes inoperable.
- The primary shut-off valves are typically operated hydraulically, ensuring quick and reliable closure when needed. To further enhance reliability, the hydraulic operations are controlled through redundant electronic circuitry and supported by multiple independent sensors. These sensors constantly monitor critical parameters such as speed, temperature, pressure, and oil levels, providing real-time feedback to the control system.
- In addition to the electronic and hydraulic protections, heavy-duty turbine units are equipped with an additional layer of safety through a hydromechanical trip system. This system provides mechanical backup protection in case of electronic system failure. It is specifically designed to respond to critical failure events such as:
- Overspeed conditions (where turbine speed exceeds safe limits),
- Loss of lubricating oil pressure (which could lead to bearing damage or seizure),
- Manual trip commands (initiated by operators during emergencies).
- Each of these protective elements—electronic, hydraulic, and hydromechanical—works together in a redundant arrangement to maximize the safety and reliability of turbine operations. The redundancy ensures that a single point of failure will not compromise the entire protection system.
- The arrangement and interactions of these redundant protective system elements are illustrated in detailed system diagrams, emphasizing the thorough, layered approach taken to safeguard turbine operations.
