January 25, 2012
A grid frequency rate limiting system (106) for a droop governor (136) is disclosed, the grid frequency rate limiting system (106) including: a rate limit calculator (130) for: obtaining data including at least one of: a transient power response requirement indicator (230), a turbo-generator power level indicator (236), a grid stability indicator (240), a fuel transfer indicator (250), a combustion mode timing indicator (260), or a temperature matching indicator (270); and defining rate limits according to the obtained data; a rate limiter (134) operably connected to the rate limit calculator (130), the rate limiter (134) for: obtaining a grid frequency reading associated with a grid frequency (210) of an electrical grid (200); obtaining the defined rate limits; and filtering the grid frequency (210) using the defined rate limits to provide a filtered frequency; and a droop governor (136) operably connected to the grid frequency rate limiting system (106), the droop governor (136) for: obtaining the filtered frequency; and providing a power response to the electrical grid (200) based upon the filtered frequency.
