What devices maintains equal power factors on paralleled AC generators automatically?

🔍 Key Concepts

• Paralleling AC generators and how load (kW) and reactive power (kVAR) are shared • Difference between voltage control and speed/governor control on generators • What device or control affects power factor / reactive power when machines are in parallel

💭 Think About

• When two AC generators are operating in parallel, which control is mainly responsible for how they share reactive power and maintain similar power factors? • Which option is more closely related to protection (tripping on abnormal conditions) rather than continuous automatic control of power factor? • Think about which device acts all the time to control output, and which ones only act during a fault or abnormal condition.

✅ Before You Answer

• Identify which choices are primarily protective relays that trip or isolate equipment, not continuous controllers • Decide which device directly adjusts terminal voltage and reactive power (kVAR) of a generator • Confirm which control (speed vs voltage) mainly affects kW sharing and which mainly affects kVAR/power factor sharing between paralleled generators
