STEAM-TURBINE NUCLEAR POWER PLANT WITH POWER MODULATION

摘要

FIELD: energy.SUBSTANCE: invention relates to atomic power engineering and is intended for use at steam-turbine plants of nuclear power plants (NPPs) of the double-loop type with water-water energetic reactors. Steam turbine NPP includes a steam generator of the reactor plant connected with a steam line to a lock-and-control valve with a turbine consisting of high and low pressure cylinders installed on one shaft with an electric generator. Cylinders are interconnected with a steam line, herewith upstream the steam there are a separator and a two-stage steam-steam superheater. Steam turbine NPP additionally contains a boiler house, which is connected with a turbodrive of the supply pump by means of a steam line with a valve of steam supply from the boiler house. Boiler house is connected to the gas pipeline from the main gas line and with the condensate pipeline from the condensate reserve tank, on which the valve of condensate supply to the boiler house is installed.EFFECT: technical result is receiving additional power and maneuverability due to generation of additional steam in the already available boiler house (BH) and its supply into the feeding pump turbodrive at the hours of electrical load schedule peaks covering.1 cl, 1 dwg
