Section 5.3 – Turbine and Engine Governors
Overview
• Equipment Control is needed for steady state output and equipment protection.
• Governors limit equipment speed and load.• Governors work in harmony in a dynamic
control system.• High speed equipment requires over speed
protection.

Dynamic Response and Speed• System response is only as fast as its slowest
component.• Response rate prevents overspeed or bog
down.• Feedback is used to prevent overspeed and
bog down.• For electric generation, speed is the key
feedback parameter.• Steam, water or fuel flow is adjusted to
maintain speed.
