🔍 Key Concepts

• Parallel operation of AC generators – what conditions must match before and after closing the breaker • Real power (kW) vs. reactive power (kVAR) – which control affects which type of load sharing • Governor speed control vs. field excitation – which one mainly changes frequency and kW, and which one mainly changes voltage and kVAR

💭 Think About

• Ask yourself: when two generators are already synchronized and connected, what adjustment will make one unit pick up more or less kW (real power) without changing system voltage much? • Consider how you would correct a situation where one generator is taking more mechanical load (prime mover effort) than the other – what control on the engine or turbine affects that? • Think about which controls are mainly electrical (voltage/reactive power) and which are mainly mechanical (speed/real power). Which type of control would be used for equal kW sharing?

✅ Before You Answer

• Verify which device directly affects prime mover speed and torque, because that is tied to kW sharing between paralleled generators. • Confirm which control is primarily used to adjust voltage and reactive power (kVAR) rather than real power. • Eliminate any options that are mainly associated with voltage regulation components rather than with sharing of real power between generators.
