What determines the division of kilowatt load between two paralleled alternators?

🔍 Key Concepts

• Real power (kW) vs reactive power (kVAR) sharing when alternators are operated in parallel • The role of governor speed droop in controlling active power output • The role of field excitation in controlling reactive power and power factor

💭 Think About

• When two alternators are running in parallel at the same frequency and voltage, which control (governor or excitation) mainly affects how much real power (kW) each machine carries? • Which control mainly affects reactive power (kVAR) and power factor, rather than the real kW load? • Think about how changing speed setpoint or droop on a governor changes shaft torque and kW output—how does that compare to what happens when you change the field current?

✅ Before You Answer

• Identify which option relates to governor control / speed droop, and which relate to field excitation • Decide which physical quantity you’re dividing between alternators: kW (real power) or kVAR (reactive power) • Verify which machine parameter directly affects torque and real power versus which affects voltage, reactive power, and power factor
