Description:
In this unit, trainees will learn what logic diagrams are and how they are used to represent the functions carried out by plant protection equipment. Common types of logic gates are identified and described, and interlock logic is examined. The unit also describes how logic diagrams can be used to represent conditions that cause boiler trips, turbine trips and generator trips, and it explains how the protection systems for boilers, turbines and generators are interrelated.

Objectives:

  • Logic Diagrams
    • Describe what logic diagrams are and how they can be used to represent functions carried out by plant protection equipment.
    • Describe the functions of AND gates, OR gates, NOT gates and time delay (TD) gates in logic circuits.
    • Describe what interlocks are and how the actions of interlocks associated with boiler operations are represented in logic diagrams.
  • Trip Logic
    • Describe how logic diagrams can be used to represent conditions that cause equipment trips.
    • Identify conditions that can cause a boiler trip and describe how a logic diagram can be used to illustrate those conditions.
    • Identify conditions that can cause a turbine trip and describe how a logic diagram can be used to illustrate those conditions.
    • Identify conditions that can cause a generator trip and describe how a logic diagram can be used to illustrate those conditions.
    • Describe how the protection systems for boilers, turbines and generators are interrelated.
