Abstract: The shaft-type instrument (1) has a shaft part (2), fixedly connected at one end to a shaft grip (3), and a sliding part (4). The sliding part (4) is displaceably mounted relative to the shaft part (2) and is, at one end, in operative connection with a pretensioned handgrip (5) such that by actuating the handgrip (5), the sliding part (4) is displaceable counter to the pretension. A respective lever arm (7, 7?) is articulated at two spaced apart shaft articulation points (6, 6?) on the shaft part (2) or shaft grip (3). The handgrip (5) has a coupling section (8) which connects the lever arms (7, 7?) and coupling joints (9, 9?) to one another such that same can pivot in the same direction. The coupling joints are spaced apart and a grip section (10) extends transverse to the coupling section (8) and to the shaft part (2).

Abstract: During an adiabatic compressed air energy storage (ACAES) system's operation, energy imbalances may arise between thermal energy storage (TES) in the system and the thermal energy required to raise the temperature of a given volume of compressed air to a desired turbine entry temperature after the air is discharged from compressed air storage of the ACAES system. To redress this energy imbalance it is proposed to selectively supply additional thermal energy to the given volume of compressed air after it received thermal energy from the TES and before it expands through the turbine. The additional thermal energy is supplied from an external source, i.e. fuel burnt in a combustor. The amount of thermal energy added to the given volume of compressed air after it received thermal energy from the TES is much smaller than the amount of useful work obtained from the given volume of compressed air by the turbine.

The method can include providing an overspeed control system with a control valve configured and located to adjust a speed of the steam turbine, the control valve having a control position. The method can also include monitoring the control position of the control valve and detecting a deloading event. Upon detection of a deloading event, a control system fault alert is generated when the control valve does not achieve a predefined control position within a predefined time from the deloading event.

In this location, an AC current is passed through the coil thus heating the component.

Abstract: During operation of a power plant, which basically comprises a gas turbogroup, a compressed air accumulator, an air turbine which is equipped with at least one generator, the compressed air which is extracted from the compressed air accumulator is directed through a heat exchanger which operates on the downstream side of the gas turbogroup, and is thermally conditioned there. This thermally conditioned compressed air then charges the air turbine for producing a quantity of electricity. Furthermore, the power plant is extended by a steam turbine, which in combined operation is operated with steam which is produced from the exhaust gases of the gas turbogroup.

Abstract: A storage power station (S), for example an air storage plant, that includes a compressor unit (V), a turbine unit (T) and a storage volume (100) can be operated using a specific method of operation, which allows as fast a reaction as possible to changes in the load demands. Rapid changes in the load demands can be satisfied by controlling the power consumption of the compressor unit (V), which results in a variable net power output, with the power output from the turbine unit (T) remaining constant. The power of the compressor unit can be controlled approximately one order of magnitude more quickly than the power generation machine can be controlled. In the extreme, the compressor unit can simply be shut down, thus resulting in its drive power becoming available to an electricity grid within seconds. During this process, the turbine unit can continue to operate normally, and can slowly follow the power demand, thus reducing the load on the turbine.
