摘要： A steam turbine system including a steam turbine which has a turbine housing and at least one turbine shaft accommodated in the turbine housing and sealed by seals, a condenser connected fluidically to the steam turbine, an evacuation unit connected fluidically to the condenser, and a dry air source which is connected fluidically to the steam turbine, wherein the steam turbine system is designed in such a way that the evacuation unit is optionally fluidically connectable to the dry air source. A method for preserving components of a steam turbine system to prevent idle-state corrosion is also provided, which the steps: shutting down a steam turbine of the steam turbine system and sucking dry air into the steam turbine using an evacuation unit which additionally functions during intended operation of the steam turbine to exhaust a resulting amount of gas into a condenser.

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： The invention relates to a control system for reducing rotor vibrations, in particular the variability thereof, in shafting, in particular turbine shafting, in which the temperature of the bearing (6) of the shaft is measured and the oil (8) supplied to the bearing is adjusted to a temperature as is assigned as the output variable in an allocation for minimised rotor vibrations with the measured temperature of the bearing as the input variable. The allocation can, for example, be provided by an initial measurement of the rotor vibrations or by a self-learning system. According to the invention, the variability of the rotor vibrations is restricted.

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.
