    摘要: A pipeline system (10) for the controlled distribution of a flowing medium comprises a main line (11) which branches at a branching point (12) into a plurality of branch lines (13,14,15), in each of the branch lines a variable restrictor (V1,V2,V3), by means of which the mass flow in each of the branch lines (13,14,15) can be adjusted and, belonging to each restrictor (V1,V2,V3), a first pressure measuring device (PM1,PM2,PM3), by means of which the pressure drop of flowing medium at the respective restrictor (V1,V2,V3) is measured. Redundancy in measurement, at a limited additional outlay, is obtained in that at least between two of the branch lines (13,14, or 13,15 or 14,15) a second pressure measuring device (PM10 or PM11 or PM12) for measuring the differential pressure between the respective branch lines (13,14 or 13,15 or 14,15) is arranged downstream of the restrictors (V1,V2 or V1,V3 or V2,V3) in the direction of flow.

    摘要: When loading a power station in a grid without any energy, this power station must be able to cover all the short-term power requirements, and at the same time to keep the grid frequency within a permissible tolerance band. The invention specifies a method of providing this capability by means of an efficient combination system. According to the invention, the gas turbine (1) is loaded in a lower power range such that it is controlled in accordance with a predetermined load program, without having to react to load transients in the grid (50). Before the power station is connected to the grid, the heat recovery steam generator (5) is heated up as an energy store, and a steam turbine (2) is raised at least to its rated rotation speed, with the steam control valves (9, 15) being highly restricted. The steam turbine reacts in the event of short-term load requirements from the grid, which cannot be covered by the gas turbine.

    摘要: A method for controlling a power plant which delivers electrical power to an electrical grid. The grid has a grid frequency which fluctuates around a nominal frequency. A power output of the power plant is controlled as a function of a control frequency, in such a manner that the power output is increased when the control frequency decreases below the nominal frequency. On the other hand the power output is decreased when the control frequency rises above the nominal frequency. The grid frequency is continuously measured. The measured grid frequency is averaged to give, as a moving average, a slowly varying averaged trend frequency which is characteristic of the long term behavior of the grid frequency. The averaged grid frequency is used as the control frequency, if the measured grid frequency lies within a predetermined band around the averaged grid frequency. The measured grid frequency is used as the control frequency, if the measured grid frequency lies outside the predetermined band.

    摘要: In a method of setting a main controlled variable during the operation of a gas-turbine group, the gas-turbine group essentially comprises a compressor (40), at least one combustion chamber (43), at least one turbine (41) and a generator (46). A desired value (3) is compared with a measured value (4) and the resulting main control difference (5) is hierarchically allocated via a management unit (1) to at least one cascade (9, 18). The cascade (9, 18) is essentially composed of a main-controlled-variable controller (6, 15) and a downstream variable controller (8, 17) which acts on the respective variable actuator (14, 23).
