    摘要： The invention introduces a method for operating a gas turbine plant (1) having a gas turbine (100) and an electric generator (200) driven by the gas turbine (100). The method has at least the following steps: detecting an instantaneous power of the gas turbine plant (1); comparing the detected instantaneous power with a power limit value; and limiting the instantaneous power when the result of the comparison is that the detected instantaneous power is equal to or greater than the power limit value. According to the invention, a step of detecting at least one operating parameter of the gas turbine plant (1) and a step of determining the power limit value as a function of the at least one detected operating parameter are then provided, wherein the at least one operating parameter of the gas turbine plant (1) comprises an ambient pressure and the power limit value is increased when the ambient pressure increases.

    摘要： The invention relates to a method for operating a gas turbine system (2) in part load operation and to an arrangement (48) for controlling a gas turbine system (2) in part load operation, and to a gas turbine system (2) having a compressor pre-guide blade adjusting device (18). According to the method, a compressor pre-guide blade adjustment for part load operation is initiated in the case of a given state of a flow medium (6) which flows into a compressor (16) of the gas turbine system (12), a value (72) of the initiated compressor pre-guide blade adjustment is compared with a compressor pre-guide blade adjustment limit value (70) which can be determined depending on the state (96, 98, 102-106) of the flow medium (6) which flows into the compressor (16) of the gas turbine system (2), and, if the value (72) of the initiated compressor pre-guide blade adjustment meets a predefined condition with regard to the compressor pre-guide blade adjustment limit value (70), at least one measure is initiated for changing the state (96, 98, 102-106) of the flow medium (6) which flows into the compressor (16) of the gas turbine system (2) in part load operation. The arrangement (48) has an actuating device (50), a determining device (52) and a control unit (54) which are prepared for carrying out the method. The gas turbine system (2) has an anti-icing device (20) and/or an intake air heating device (12) and the arrangement (48).

    摘要： The invention relates to a heat shield element (22) for a heat shield having a support structure (24). The heat shield element (22) comprises a hot side (26) which can be exposed to hot gas, a cold side (28) opposite the hot side (26), and peripheral sides (30a, 30b) connecting the hot side (26) to the cold side (28). The heat shield element (22) can be fastened to the support structure (24) of the heat shield with the cold side (28) facing the support structure (24) and has a height (34, 36) running vertically to the cold side (26). The heat shield element (22) allows damage to components of a combustion chamber caused by the entry of hot gas to be avoided in a particularly effective manner. For this purpose, the height of the heat shield element (22) increases in a rising direction (32), the rising portion of the heat shield element (22) running in the rising direction (32) substantially up to at least one peripheral side (30a, 30b) or up to a projection (38) that extends the hot side (26) over the base surface of the cold side (28).
