摘要：
The invention relates to a method for operating a combined cycle power plant, which includes a steam turbine powertrain with a high-pressure steam turbine, an intermediate pressure steam turbine and a low-pressure steam turbine, whereby intermediate pressure steam flowing from the exit of the high-pressure steam turbine to the inlet of the intermediate pressure steam turbine is reheated by means of the reheat device, and which is connected to a solar thermal plant, that generates additional solar steam for being used by said steam turbine powertrain. The output of the solar steam generator is used more effectively, and the overall plant performance, flexibility and operability are enhanced by at least part of the additional solar steam reaching the intermediate pressure steam turbine without being reheated in said reheat device.
