🔍 Key Concepts

• Real power (kW) vs reactive power (kVAR) and which one changes with speed/governor versus voltage/field • How paralleled generators share load: one device mainly adjusts frequency/speed, another adjusts voltage/reactive load • Difference between devices used for measurement and those used for control/load sharing

💭 Think About

• When two AC generators are in parallel and you want to change how many kilowatts each one carries, what physical quantity must you change: speed/frequency or voltage/excitation? • Which component on a generator directly affects engine speed and fuel input, and which affects field excitation and terminal voltage? • Look at each choice and ask: does this device actually control kW load sharing, or is it meant for voltage control/field current or just measuring RPM?

✅ Before You Answer

• Be clear on which device controls speed/governor setting → kW (real power) sharing • Separate in your mind voltage/reactive power (kVAR) control from real power (kW) control • Eliminate any option that is only a measurement tool or is primarily for field voltage adjustment rather than active power sharing

What device is used so that the kilowatt load sharing can be adjusted on paralleled generators?

field rheostat

governor control

automatic voltage regulators

hand tachometer
