Definitions
- the invention relates to a method for avoiding pump surges in a compressor, in which a plurality of characteristics of the compressor is monitored during operation and a setpoint range for the plurality of characteristics is given, which in case of exceeding or falling below a number of characteristics from the setpoint range, a pumping shock counteracting reaction is triggered. It further relates to a compressor and a turbomachine with a compressor and a control device which is connected on the data input side to a plurality of sensors, which are designed to detect parameters during operation.
- Compressors especially gas turbines, tend to pump under certain operating conditions. If the counter-pressure in the direction of flow becomes too great, then the compressor can no longer convey air and the direction of flow reverses locally or even completely. With local backflow, a portion of the air trapped in the compressor and rotates with the blades with. One speaks of a rotating separation of the flow (rotating stall). In contrast, (deep surge) flows in so-called compressor pumps the medium completely back - there is a vehement shock opposite to the thrust direction ⁇ .
- a surge margin is defined, which is sufficiently far away from the surge limit in operation at design conditions.
- rea ⁇ len conditions such. B. with decreasing power frequency, high ambient temperatures and / or air humidity, low calorific values of fuels, but also by aging, contamination or damage to the compressor, it may happen that the surge line reaches the operating characteristic or even falls below. This then leads to immediate pumping of the compressor.
- a compressor pressure ratio limiting regulator is therefore often used.
- a controller of this kind looks at compressor characteristics (pressure ratio, line frequency, guide vane position and ambient conditions such as temperature and air humidity) and compares these with permissible values from a compressor-specific zifischen pumping limit map.
- a disadvantage of both mentioned methods is that they do not take into account aging, massive contamination or damage to the compressor and thus can no longer reliably prevent pumping of the compressor as the running time of the turbomachine increases.
- EP2375081 A2 proposes to use shock waves and other acoustic phenomena of the compressed air for pump prediction. Again, microphones or similar pressure sensors are used. The disadvantage, however, is that such sensors only have a limited service life at higher ambient temperatures.
- the invention is therefore based on the object to provide a method for preventing pump surges in a compressor, a compressor or a turbomachine, which reliably prevent pumping of the compressor even at relatively high mileage.
- the object is solved because ⁇ by that the plurality of parameters comprises a sound associated with the rotation of the compressor characteristic.
- the invention is based on the consideration that for a ne, even at higher mileage of the turbomachine reliable prevention of pump surges should not be resorted exclusively to pre-defined maps and controllable operating variables ⁇ , but rather current, for preventive detection of impending surge should be used appropriate measures. Predictive detection would be possible if an approximation to the surge limit in the form of the rotating stall, ie the rotating flow separation, could already be detected by appropriate measurements.
- Strömungsablö ⁇ solution vibrations generated in the compressor stages which lead to increased pressure pulsations and other vibrations.
- the measured characteristic assigned to the rotary sound of the compressor is advantageously a vibration amplitude and / or frequency of a component of the turbomachine.
- the pressure pulsations übertra ⁇ gen in fact on the components of the flow machine.
- the suitable sensors and encoders are less sensitive to the operating conditions mentioned and thus more durable.
- the shaft and / or the housing of the turbine and / or the compressor Based on the housing and / or wel- Vibrations of turbine and / or compressor, the rotary sound can be particularly well determined with regard to an imminent approach to the surge line.
- the characteristics used further include the shaft speed, the compressor discharge pressure and / or the Vorleitschaufelhorn.
- the predictive recognition of the pumping can be further improved, since the rotary sound can be determined particularly well with the aid of these additional parameters, for example in a computer specially provided for the measurement with special evaluation algorithms.
- the counteracting the pump surge reaction comprises a reduction of the target value ⁇ the turbine outlet temperature and / or a reduction of the fuel mass flow.
- the Strö ⁇ tion machine has a reduction of the nominal value of the turbines ⁇ outlet temperature means that the adjustable pre opens guide vanes of the compressor. This increases the distance to the surge line.
- the compaction ⁇ dioxideddruck and the compressor pressure ratio graces redu ⁇ .
- z. B. removed by the anti-icing valve of the compressor at the compressor end of the air ⁇ who. Improving then the air extraction via the anti-icing valve can be re-introduced at the compressor inlet. This makes the compressor pressure ratio is also redu ⁇ ed.
- a turbomachine with a Ver ⁇ denser and a control device for performing the method described is formed.
- the turbomachine having a compressor and ei ⁇ ner control means which is the data input side connected to a plurality of sensors designed to detect parameters during operation
- the Problem solved in that one of the sensors for detecting a rotational sound of the compressor associated characteristic is formed.
- the respective sensor is a sensor oscillations ⁇ supply.
- This is advantageously designed as a vibrometer.
- vibrometers which measure accelerations on a piezoelectric basis, such as, for example, the piezoelectric accelerometer CA 901 from Meggitt. This is especially durable and robust ge ⁇ genüber high temperatures, dirt and compressor washes.
- the respective sensor of the shaft and / or the housing of the turbine and / or the compressor is assigned.
- corresponding sensors are advantageously mounted at several points on the circumference of the compressor, ideally in Klingelbohrungen outside, d. H. not in the flow path.
- a power plant advantageously comprises a be ⁇ written turbomachine .
- the advantages achieved by the invention are in particular that can be seen by the targeted measurement of the rotational sound of the compressor of a turbomachine approach to the surge line or a rotating stall before an actual pumping occurs.
- This can be especially a ⁇ times achieved by appropriate vibration sensors, measure the pressure changes of rotating compressor blades of a stage.
- Other donors shaft speed, compressor discharge, Vorleitschaufel too
- As a computer with special evaluation algorithms determine. This also makes it possible to detect foreign bodies which can lead to damage to the compressor flow path and its Tei ⁇ len. Namely, such foreign bodies also lead to a change of the rotary sound. Subsequent damage to components downstream of the compressor can thus be avoided.
- FIG. 1 shows schematically a section through the upper half of a compressor of a gas turbine.
- the Strömungsmaschi ⁇ ne 1 shown in detail in Figure 1 is designed as a gas turbine. From the gas turbine, only the compressor 2 is shown.
- the compressor 2 comprises fixed to a housing 4 and thus fixed Leit ⁇ blades 6, which are located in a flow channel 8 between the compressor inlet 10 and the compressor outlet 12.
- the first vane 6 in the flow direction of the air is configured as an adjustable guide vane 14. As a result, the air supply can be regulated and throttled in the flow channel 8.
- each vane 6 14 16 blades 18 are each arranged on a shaft.
- the blades 18 and the guide vanes 6, 14 are each arranged in a star shape in rings in the flow channel 8.
- vibration sensors 20 are mounted in each 90 ° angularly mounted bell holes that detect mechanical vibrations and thus allow an image of the rotational sound of the compressor 2.
- the rotation sound is by means of an evaluation algorithm 22 it ⁇ averages, which as software on a non-illustrated control means, for. B. a computer is implemented.
- the evaluation algorithm data of the vibration sensors 20, the data of other corresponding encoder or sensors include the shaft speed, the compressor pressure ratio between the compressor inlet 10 and the compressor outlet 12, the guide vane position, the shaft vibration and the housing vibration at the compressor and turbine.
- the computer sends signals (binary or analog) to perform appropriate reactions to prevent pumping.
- the reactions include opening the anti-icing valve 24, lowering the turbine exit temperature 26 and reducing the amount of fuel 28. Other measures may also be provided.
- the reactions can be triggered as required depending on the determined by the evaluation algorithm 22 result ⁇ sen. Thus, for example, only a few of the reactions mentioned can take place or else a majority. Furthermore, messages can be sent to operating personnel 30.
