摘要： A method and associated control device for synchronizing a turbine with an alternating current network having a network frequency, having the following steps: A) accelerating the turbine up to a frequency in the range of the network frequency; B) sensing an angle difference between the turbine and the alternating current network; C) sensing a speed difference between the turbine and the alternating current network; D) accelerating or decelerating the turbine such that the turbine follows a desired trajectory, wherein the desired trajectory is a trajectory calculated in advance that indicates, in dependence on the angle difference, a desired speed difference that should be present such that a target angular position between the turbine and the alternating current network suitable for synchronous feed-in is achieved when the speed of the turbine and the speed of the alternating current network correspond.

摘要： A method for synchronising a turbine with an AC network having a network frequency, having the following steps: A) accelerating the turbine up to a stated rotational speed, without taking into consideration a difference angle between the turbine and the AC network; B) detecting a difference angle between the turbine and the AC network; C) accelerating or decelerating the turbine in such a way that the differential speed follows a target trajectory, wherein the target trajectory is a trajectory that indicates a target rotational speed depending on the detected difference angle, such that a target angular position that is suitable for a synchronous supply is achieved between the turbine and AC network.

摘要： A method for starting a steam turbine system having a steam generator, a steam turbine which is connected to the steam generator and includes at least two turbine stages that, at the time of starting the steam turbine system, have different outlet temperatures, a condenser connected to the steam turbine and a consumer driven by the steam turbine, in which the steam generated in the steam generator is used to start the steam turbine, wherein, until the steam generated in the steam generator reaches a predetermined temperature that at least corresponds to the temperature requirement of the turbine stage with the higher outlet temperature, only the turbine stage with the lower outlet temperature is operated, and in that the turbine stage with the higher outlet temperature is brought on-line only once the predetermined temperature has been reached.

摘要： A method for operating a combined cycle power plant, wherein the combined cycle power plant has a gas turbine and a steam turbine and also a shutting-down device, and wherein, for shutting down the gas turbine and the steam turbine, the gas turbine and the steam turbine are operated within a time window that extends from the beginning of the shutting-down procedure at a first time to the falling of the steam temperature to a lower limit value at a second time by the shutting device in such a way that the gas turbine and the steam turbine are relieved substantially at the same time and the block power falls to zero, thermal energy that is stored in the combined cycle power plant preventing immediate falling of a steam temperature to operation below a minimum power output of the gas turbine within the time window.

摘要： 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.
