PROBLEM TO BE SOLVED: To provide a steam turbine system capable of stably performing overload operation.SOLUTION: A main steam pipe is supplied with steam from a boiler and allows the supplied steam to flow therein. A main steam regulator valve is installed on the main steam pipe and regulates a flow rate of the steam flowing therein. An overload steam pipe, where a portion of the steam diverging from the steam flowing from the boiler in the main steam pipe flows into the overload steam pipe at an upstream side of the main steam pipe closer to the boiler than an installation position of the main steam regulator valve, allows the diverged steam to flow in the overload steam pipe. An overload valve is installed on the overload steam pipe and regulates the flow rate of the steam flowing therein. One end of a warming pipe is connected to a section downstream of the main steam pipe closer to the steam turbine than the installation position of the main steam regulator valve and the other end of the warming pipe is connected to the section downstream of the overload steam pipe closer to the steam turbine than the installation position of the overload valve. |
