Q

A diesel generator has just been paralleled with an AC turbo generator, but the load can not be properly divided. This could be caused by __________.

🔍 Key Concepts

• Real power (kW) load sharing between paralleled AC generators is controlled by the governor/speed-droop characteristics, not by voltage regulators • A reverse power relay is a protection device that trips under certain conditions; think about whether it affects steady load division or prevents motoring • Understand the difference between droop governing and isochronous governing when generators operate in parallel

💭 Think About

• When two generators are in parallel and one is taking too much or too little load, which governor-related adjustment most directly affects how the kW load divides between them? • Would a faulty reverse power relay typically cause improper load sharing, or would it more likely cause one generator to trip or fail to stay on the bus? • If two units do not share the same governing mode or their droop/speed settings are mismatched, what happens to how the real power load is split?

✅ Before You Answer

• Verify which component directly sets the speed–load (droop) curve for each generator and therefore its share of kW when paralleled • Check whether reverse power protection is normally active and stable during normal load sharing, or only during abnormal power flow (motoring) • Compare whether "different speed setting" and "droop/isochronous settings" are describing the same underlying issue or if one is more technically precise for parallel load division problems
