🔍 Key Concepts

• How real power (kW) sharing works between generators operating in parallel • Difference between governor speed setting (frequency/real load) and voltage regulator setting (voltage/reactive load) • Interpreting the kW meters on Panel 1 and Panel 3 in the EL-0003 diagram

💭 Think About

• When two generators are in parallel and one kW meter shows a higher reading, which control (governor vs voltage regulator) directly changes real power output of that machine? • If Generator 3 is carrying too much real load, what adjustment would you make to its control, and what opposite adjustment would you make to the other generator so the bus frequency remains within limits? • Looking at the illustration, which controls are tied to the turbine/governor versus to the exciter/field, and how does that guide which knobs you should touch to balance kW?

✅ Before You Answer

• Be sure you are adjusting real power (kW), not reactive power (kVAR) or power factor. • Confirm which panel controls are labeled for governor speed and which for voltage regulation in the EL-0003 layout. • Verify that your chosen procedure changes the kW sharing between generators without unintentionally changing overall bus voltage.
