🔍 Key Concepts

• Mechanical-hydraulic governors: how small mechanical motion is turned into hydraulic power • Pilot valve and servomotor: how they work together to move larger valves or mechanisms • Difference between speed/load control and voltage control on a turbo-generator

💭 Think About

• Ask yourself: what is the basic job of a hydraulic servomotor in any control system – is it to sense, to amplify force, or to measure electricity? • Think about which part of a turbo-generator actually needs a large force to move, and how a small governor movement can control that large movement. • Decide whether the governor mainly controls electrical characteristics (like voltage) or mechanical ones (like steam flow, speed, and load).

✅ Before You Answer

• Identify whether pilot valves usually handle small control flows or large main flows of fluid. • Determine which component in a turbo-generator actually controls steam flow to the turbine. • Separate in your mind the role of the excitation/AVR (automatic voltage regulator) from the role of the mechanical-hydraulic governor.
