What must be done to manually equalize the power factor of two alternators operating in parallel?

🔍 Key Concepts

• Effect of voltage regulator on reactive (kVAR) load sharing between alternators in parallel • Effect of governor speed setting on real (kW) load sharing between alternators in parallel • Relationship between power factor, reactive power, and field excitation

💭 Think About

• When two alternators are running in parallel and you want to change power factor (not kW load), which control—voltage regulator or governor—directly affects reactive power? • If one machine is taking more reactive (kVAR) load than the other, in which direction would you move the controls to make their reactive loads more equal? • Does moving both controls the same way tend to keep them equal or make one take more and the other less?

✅ Before You Answer

• Identify which control affects kW (real power) and which affects kVAR (reactive power) • Focus on the control that changes field excitation/terminal voltage, not shaft speed, when dealing with power factor • Decide whether the adjustment to both machines should be in the same direction or opposite directions to equalize their reactive loads
