What are the most common definitions and deliverables that customers expect from a Genset?
They expect measurable power density, load acceptance, emissions, fuel consumption and noise. Power density measures the rating over the volume of the engine; the higher the power density is the more effective the Genset can be. Load Acceptance – Gensets are often used for standby/emergency power, where they will be expected to start-up, run up to running speed and then accept a large % of maximum electrical load. Load acceptance is measured in terms of a % frequency dip and a recovery time, and is defined by ISO 8528-5 and NFPA 99/110. Additional requirements are customer driven demanding typically 80% of the prime rating within 10 seconds of start-up, within ISO 8528-5 limits. Engine load acceptance has been demonstrated as a linear function of trapped mass.
