The reheat steam turbine plant and the reheat steam

摘要

PROBLEM TO BE SOLVED: To provide a reheat steam turbine plant performing stable supply of steam to other system while keeping pressure of steam generated from a steam generator high even if stop command such as a trip is issued to a steam turbine, and a method for operating the same.;SOLUTION: This invented reheat steam turbine plant is provided with a ventilator system 43 connecting a high pressure turbine 25 and a middle pressure turbine 26, a first steam supply system 44 branching from a middle between a high pressure turbine bypass system 36 and a main steam stop valve 30 in a main steam system 32 of the steam generator 22, a second steam supply system 45 branching from a middle between a low pressure turbine bypass system 38 and a reheat steam stop valve 39 in a high temperature reheat steam system 41 of the steam generator 22.;COPYRIGHT: (C)2005,JPO&NCIPI
