  • Publication number: 20210285333
    Abstract: A method for checking a steam turbine, wherein a first operating variable and a second operating variable are determined, wherein a correlation between the first and second operating variable prevails, and a confidence band having an upper maximum value and a lower minimum value is created, wherein a notification is generated as long as the second operating variable is outside the confidence band during operation.

  • Publication number: 20190305705
    Abstract: A method for supplying an excitation current to an excitation winding of a rotor of a three-phase generator of a system for producing a three-phase alternating voltage to be fed into a power network. A pulsed excitation current is supplied to the excitation winding if a rotational frequency of the rotor deviates from a network frequency of the power network.

  • Patent number: 10302527
    Abstract: 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.

  • Patent number: 10167742
    Abstract: A steam cycle for a power station, and to a method for operating, in particular for starting, a steam cycle. The steam cycle has a high-pressure turbine, a condenser and a steam generator. The steam generator is connected to the high-pressure turbine via a first line. Live steam quick-closing valves and live steam regulating valves for supplying the high-pressure turbine are arranged in the direction of the steam flow between the steam generator and the high-pressure turbine. A starting line is arranged downstream of the high-pressure turbine in the direction of the steam flow, the starting line connecting a waste steam region downstream of the high-pressure turbine with the condenser. At least one regulator regulates a closing of a starting valve for sealing the starting line, and an opening of the live steam valve, depending on the rotational speed, a temperature and load state of the high-pressure turbine.

  • Publication number: 20170183977
    Abstract: 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.
