← TechnologyWhich outcome results when a hydroelectric turbine's speed control system excessively dampens wicket gate adjustments?
A)Extended settling time occurs✓
B)Increased penstock water hammer
C)Generator over-speeding is reduced
D)Reduced turbine wear is seen
💡 Explanation
Excessive damping in the control loop employs critical damping, therefore a slower return to a steady state during load variations results, because it suppresses oscillatory behavior. This leads to extended settling time rather than water hammer issues; generator faults, or reduced mechanical wear.
