How do two online generators share the load?

• A. They equally share the load, each supplying 50%.
• B. The first generator carries 70% and the second 30%.
• C. The bus directs power to the APU to balance.
• D. The GPUs handle the load.

Answer: (A)

When two generators operate in parallel, the load they supply is managed by their control systems so the bus stays at the correct voltage and frequency. Each generator has a governor that senses the system frequency and adjusts the mechanical input to match the required electrical output. If both units are identical in rating and tuned the same way, their governors respond similarly, so the load splits evenly. In that ideal case, each generator handles about half the total demand.

The other ideas don’t describe how parallel sharing works: power isn’t steered to an APU or directed by GPUs for balance, and those concepts don’t apply to how electrical generators share load.
