A method is provided for carrying out a sound test for detecting and/or analyzing material faults and/or mounting faults of at least one component, in which the component is excited, by striking, to experience vibrations which generate soundwaves, after which the generated soundwaves are detected and conclusions are drawn about material faults and/or mounting faults on the basis of the detected soundwaves, wherein the striking of the component and the detection of the vibrations are carried out using an endoscope device. In addition, embodiments of the present invention relates to an endoscope device which is configured to carry out the method.

Method for carrying out a sound test of atleast one component and endoscope device used for the same

A method for operating a steam power station is provided. The steam turbine power station includes at least one steam turbine and a process steam consumer, wherein a steam mass flow is subdivided into a first partial mass flow and a second partial mass. In a first operating state, the first partial mass flow is supplied to the steam turbine and the second partial mass flow is supplied to the process steam consumer. In a second operating state, at least part of the second partial mass flow is supplied to the steam turbine at least after the first turbine stages. A steam power station is also provided.

Method and device for operating a steam power station comprising a steam turbine and a process steam consumer

A method for operating a gas and steam turbine system is provided. The system includes a frequency converter which is assigned to a starting device of a gas turbine, and a generator which is assigned to a steam turbine. The intention is to be able to obtain a particularly high level of operational flexibility with particularly low mechanical complexity. For this purpose, the electrical power of the generator is fed into a consumer system via the frequency converter.
