GE IC3606SASB1

A turbine startup is a complex, multi-step process that requires perfect timing and coordination. The IC3606SASB1 ensures this by:

  • Startup Logic: The card contains the logic that governs the startup sequence. It ensures that each step—such as igniting the fuel, accelerating the turbine, and synchronizing with the grid—occurs only after the previous step has been successfully completed and verified.
  • Signal Integration: It works by receiving input signals from various sensors (e.g., speed sensors, pressure sensors) and other control cards to verify that the turbine is in the correct state to proceed.
  • Providing Control Outputs: Once a step is complete, the card provides an output signal to the next part of the control system, which then initiates the next step in the sequence. For example, it might signal a fuel control card to increase fuel flow once the turbine has reached a minimum ignition speed.
  • Safety and Interlocks: It is a critical component for safety. If a condition is not met during the startup sequence (e.g., if oil pressure is too low), the card will halt the sequence and can trigger an alarm or a protective shutdown, preventing damage to the turbine.
  • Robust Design: Like all GE industrial control boards, it is built to withstand the harsh conditions of a power plant, including vibrations, temperature fluctuations, and electromagnetic interference.

Applications

 

The IC3606SASB1 is a legacy component, so it is primarily used in power generation facilities that still operate GE’s older Mark I and Mark II turbine control systems. It is an essential component for:

  • Automated Startup: It automates a process that would otherwise require complex manual intervention.
  • System Reliability: By ensuring a safe and repeatable startup, it contributes to the overall reliability and longevity of the turbine.
