Abstract
A steam turbine system including a steam turbine is provided. The steam turbine system includes a high-pressure side steam inlet device, a low-pressure side steam device, and a control device for controlling the steam turbine. An additional steam inlet device is also included arranged between the high-pressure side steam inlet device and the low-pressure side steam device. The control device control a supply of steam via the additional steam inlet device as a function of operating parameters detected at the steam turbine system.

A steam turbine system including a steam turbine, comprising:
- a high-pressure side steam inlet device;
- a low-pressure side steam outlet device;
- a control device for controlling the steam turbine;
- an additional steam inlet device, arranged between the high-pressure side steam inlet device and the low-pressure side steam outlet device,
- wherein the control device is designed to control a supply of steam for power generation via the additional steam inlet device as a function of operating parameters detected at the steam turbine system,
- wherein the detected operating parameters include a temperature measure in a low-pressure section of the steam turbine, and
- wherein the control device is configured to effect a supply of steam for power generation via the additional steam inlet device when a certain temperature increase is detected in the low-pressure section of the steam turbine.
