Common problems with 800kw diesel generator
Can you design a containerized “power house” solution around an 800kW generator?
Absolutely. We specialize in designing and fabricating modular, containerized power plants that house the 800kW genset, fuel system, switchgear, and cooling in a single, weatherproof, and transportable unit.
How do you manage harmonic distortion in such a large generator?
We employ design techniques in the alternator and can recommend/add external harmonic filters to ensure total harmonic distortion (THDi) is kept below 5%, protecting sensitive connected equipment.
What are the typical requirements for factory acceptance testing (FAT)?
FAT is a critical step. We conduct full-load, performance, and control logic tests at our facility. Clients are welcome to witness the FAT, and we provide a detailed report with all results for project documentation.
What is your experience with EPC contractors?
We regularly work as the designated power system supplier for global EPC firms. We understand the requirements for detailed documentation, milestone payments, and strict adherence to project schedules.
