🔍 Key Concepts

• Paralleling alternators: what conditions must be matched before closing the breaker (frequency, phase, voltage) vs. what is adjusted after they are on the same bus • Difference between voltage/reactive (kVAR) sharing and kW (real power) load sharing between generators • How changes in governor speed setting vs. voltage regulator setting affect load sharing

💭 Think About

• Once two alternators are already synchronized and the breaker is closed, which quantity is normally used to control how much real power each machine carries? • Which quantity, when adjusted after closing the breaker, mainly affects reactive current and power factor rather than real kW load? • Think about what you would watch on the switchboard meters right after you parallel the second alternator: which meter do you try to equalize so that one machine doesn’t do most of the work?

✅ Before You Answer

• Verify which parameter (voltage, frequency, phase) must be matched before closing the breaker, not after • Identify which control (governor vs. AVR) primarily changes real power (kW) sharing between paralleled alternators • Confirm which adjustment is used mainly for reactive power and power factor sharing, not for balancing the real load
