AuTOMATIC SYSTEM FOr rEGuLATING ThE PErFOrMANCE OF ThE TurBINE DrIVEN PuMPS OF AN NPP POWEr uNIT WITh A WWEr-1000 rEACTOr This article discusses the technological section of the turbine driven pumps group belonging to the second circuit of the NPP power unit. Тurbine driven pumps are designed to supply feed water from deaerators through a high-pressure regeneration system to steam generators. «ПТА 3750-75» turbine driven pumping units are used at NPPs with a VVER-1000 reactor. The main regulated parameters is the discharge water flow rate[1, p. 99-102]. The control of turbine driven pumps is carried out with the help of digital PI-regulators on the basis of the automatic control system of the turbine compartment.
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.
