Abstract:Many researches have focused on the stability analysis of power systems based on frequency response models. A constant gain value is often used to represent a governing system of a prime mover, which may be proper for a classic hydraulic governor but not suitable for modern digital electro-hydraulic (DEH) control systems. PID controllers, pressure or load feedbacks, frequency deviation feed-forwards and coordinated boiler-turbine controls are used widely for practical generation units to optimize the response … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
