Customer Requirements
Project Background：
The customer needs to conduct on-site load testing of the ship's power generation system to verify:
Rated output capacity of the generator set；
Steady-state voltage and frequency performance；
Response capability under load variation；
Power factor adjustment capability；
Compliance with classification society acceptance requirements；
Due to limited space on board the vessel and the requirement for operation in marine environments, the customer requires a large-scale load testing solution featuring:
▸ High power density；
▸ Outdoor protection design；
▸ Mobile deployment；
▸ Precise load control；
▸ Support for resistive-inductive testing；
