Q

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

If the question has a related picture, it will appear here.

🔍 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
