Definitions
- the present invention relates to a combined control method for vapor thermodynamic cycles and is particularly suitable for an organic Rankine cycle (hereafter, also ORC cycle).
- the control method is said combined for the simultaneous presence of a vapor admission valve in the turbine and a by-pass valve of the same turbine and thus for the adjustment by means of both valves
- thermodynamic cycle is a finite sequence of thermodynamic processes (e.g. isothermal, isochoric, isobaric and adiabatic processes) after which a system returns to its initial state.
- thermodynamic cycle is a thermodynamic cycle comprising two adiabatic processes and two isobars. Its purpose is to transform heat into work.
- This cycle is generally adopted principally in thermal power plants for the production of electrical energy and uses as working fluid, water, either in liquid form or in the form of steam, with the so-called steam turbine.
- ORC organic Rankine cycle
- the system for an ORC cycle includes one or more pumps to supply the organic working fluid, one or more heat exchangers to achieve preheating, vaporization and possible overheating stages or heating stage for supercritical working fluid, a steam turbine for the expansion of the fluid, the turbine being mechanically connected to an electric generator or to a working machine, a condenser that returns the organic working fluid in the liquid state and eventually a regenerator to recover the heat downstream of the turbine and upstream of the condenser.
- the supply of the turbine is realized by means of one or more admission lines, controlled by corresponding control valves.
- one or more by-pass lines controlled by corresponding by-pass valves.
- the organic working fluid from the evaporator passes through the turbine with its maximum rate, in order to produce the maximum power.
- the admission valve is open 100% and the by-pass valve is fully closed.
- the system operator or the grid operator can require a quick adjustment of the supplied power, with a time response of few seconds; in other words, it may be required that the power is reduced in a few seconds to reach a desired value (set point).
- the admission valve AV closes partially by means of a isenthalpic process
- the fluid pressure is reduced at the turbine inlet, so as to decrease the power produced.
- the pressure reduction also involves a reduction of the fluid flow rate through the turbine. Therefore, the flow coming from the evaporator is lower and, consequently, the evaporator pressure begins to grow, due to an imbalance between the flow rate of the liquid entering the evaporator and the flow rate of the steam exiting the evaporator (more steam is produced than needed by the turbine). Therefore, it is understandable that the entire thermodynamic cycle is conditioned by an adjustment made by acting solely on the admission valve. This adjustment creates instability in some controls, for example in the control of the supply pump of the organic working fluid, because of rapid changes in the operating conditions. In cogeneration systems in which the heat discharged to the condenser is used, a variation of the heat supply to the user would also occur.
- Aim of the present invention is to provide a combined control method for vapor thermodynamic cycles, in particular for ORC cycles, that is able to avoid the above described drawbacks.
- the control method will exploit the simultaneous presence of the vapor admission valve in the turbine and the by-pass valve of the same turbine, performing a combined adjustment that uses both valves.
- a further embodiment of the present invention is an organic Rankine cycle power plant, comprising at least one feed pump, at least one heat exchanger, an expansion turbine, a condenser and a control unit configured to operate a method according to any of the embodiments described above.
- the method can be performed by means of a computer program, comprising a software to perform all the steps of the above described method, in the form of computer program product comprising the computer program.
- the computer program product can be configured as a controller for an Organic Rankine cycle power plant, comprising a control unit, a data carrier and a computer program stored on the data carrier, so that the controller defines the embodiments of the invention in the same way as defined by the method.
- the controller executes the computer program, they are also carried out all of the method steps as described above.
- FIG. 1 schematically represents an ORC plant, for which the control method according to the present invention can be used;
- Figure 2 is a graph showing the typical relationship between the flow coefficient of a throttle valve, both admission or by-pass valve, and the opening degree of the valve itself;
- FIG. 3 is a graph showing the output power, expressed as a percentage of the nominal power, as a function of the opening degree of the admission valve, in a typical installation;
- Figure 4 is a further graph showing the relationship between the opening degree of the admission valve and the opening degree of the by- pass valve, to maintain a constant total flow rate
- Figure 5 is a logic diagram which allows to obtain the opening degree of both admission valve and by-pass valve as a function of the power set point;
- Figure 6 is a block diagram that allows a system finer adjustment by means of a feedback control.
- ORC Organic Rankine cycle
- the power plant typically comprises at least a feed pump 1 to supply an organic working fluid, in liquid phase, to at least one heat exchanger 2.
- the heat exchanger which can in turn comprise a preheater, an evaporator and a superheater, the organic working fluid is heated until the change into the vapor phase and its possible overheating.
- the vapor passes through an expansion turbine 3 producing the positive work of the ORC cycle.
- Such work is a positive mechanical work collected to the turbine shaft which is rigidly connected with an electric machine or other processing machine, for example an electric generator 4 which receives mechanical energy and transforms it into electrical energy.
- the organic working fluid passes through a condenser 5 that transforms it in the liquid phase to be sent from the pump 2 again to the heat exchanger.
- a heat regenerator unit 6 can be added, i.e. a heat exchanger which exchanges heat between the organic working fluid in liquid phase, which is pumped by the pump 1 to the heat exchanger 2 and the organic working fluid in vapor phase that from the turbine 3 is directed to the condenser 5.
- the supply of the organic working fluid in vapor phase to the expansion turbine 3 is realized by means of at least one admission line 7, controlled by a corresponding admission valve AV.
- at least one by-pass line 8 is provided, said bypass line directly connecting the heat exchanger 2 with the heat regenerator unit 6 or with the condenser 5 and controlled by a corresponding by-pass valve BV.
- a control unit manages all control processes of the power plant.
- the organic working fluid coming from the heat exchangers 2 passes through the expansion turbine 3 with its maximum flow rate, in order to produce the maximum possible power.
- the admission valve AV is 100% open and the by-pass valve BV is fully closed.
- the consequent reduction of the flow rate of the organic working fluid, due to the partial closure of the admission valve AV, can be compensated by suitably opening the by-pass valve BV.
- the flow rate of the organic working fluid that passes through the by-pass valve BV must be substantially equal to the difference between the flow rate corresponding to maximum power (with the admission valve AV 100% open and the by-pass valve closed) and the flow rate of the organic working fluid which passes through the admission valve AV, in partiaiized conditions, as required by the power plant controller.
- the flow rate of the fluid flowing out from the heat exchanger 2 will not be modified, thus avoiding control instabilities suffered by the known applications.
- the thermal power supplied to the condenser and then to users in the event of thermal cogeneration power plant remains almost unaltered.
- the produced electrical power (and therefore the efficiency) will be reduced since a part of the thermal power extracted from the hot source is directly dissipated by the fluid flow rate which reaches the heat regenerator unit 6 or the condenser 5 through the by- pass line 8.
- the power plant is a cogeneration type, i.e. a power plant for the production of electric and thermal power, the power discharged on the condenser is used for the thermal loads and therefore is not dissipated.
- thermodynamic cycle does not change if the total flow rate of the organic working fluid does not change either, nor the control logic of the cycle itself is modified, with respect to standard operating conditions. Therefore, oscillations of the fluid level or disturbances in general will be so avoided, not leading to instability in the control itself or variations of the thermal power discharged to the condenser.
- the admission valve AV unlike the admission valve AV, the whole pressure drop existing between the heat exchanger (evaporator) 2 and the condenser 5 is applied to the by-pass valve BV, and therefore the latter valve usually operates in sonic conditions. It should be noted that the admission valve AV operates in sonic conditions only below a certain opening degree, in other words, when the valve is almost closed (if the evaporation and the condensation pressures are in a ratio greater than the so called "critical" one);
- Fig. 2 there is an example of a graph showing the relationship between the flow coefficient Cv of an admission valve (or by-pass valve) and the opening degree %AV, %BV of the valve itself;
- the turbine normally operates under sonic conditions, and therefore the adjustment on the admission valve AV should produce a significant pressure drop in order to obtain a not negligible power reduction.
- the variation of the output power %P as a function of the same opening degree %AV has a strongly non-linear behavior. In other words, almost all power variation (in the example in Fig. 3, from 10% to 90%) is obtained by varying the opening degree %AV of the valve from 20% to 40%. Out of this range, the variation of the opening degree %AV implies negligible changes of the output power;
- the adjustment curves of the admission valve AV and the by-pass valve BV are theoretically calculated on the basis of the flow coefficients of the same valves and according to the specific application. Alternatively, such adjustment curves can be evaluated experimentally by searching for each opening degree of the admission valve AV the corresponding opening degree of the by-pass valve BV which maintains the same total flow rate.
- Fig. 5 shows a logic diagram that allows to apply the proposed method, according to one aspect of the present invention.
- this method allows to obtain the opening degree of both admission and bypass valves as a function of the power set point.
- the set point of the desired power S500 corresponding to the electrical energy request, sets S510 the opening degree %AV of the admission valve and the latter sets S520 the opening degree %BV of the by-pass valve, in order to ensure that the total flow rate of the organic working fluid remains unchanged. Therefore, in the presence of a predetermined electric power request, this method allows to establish S530 both the corresponding values of the opening degree %AV, %BV of the admission valve AV and the bypass valve BV.
- the expansion turbine 3 operates at rated power with the admission valve AV fully open and the by-pass valve BV fully closed.
- the supervisor of the power plant requires a power equal to 10% of the rated value, and then, from the Fig. 3 graph, the admission valve AV should be choked with an opening degree %AV equal to 20%.
- the by-pass valve BV must be opened with an opening degree %BV of about 30%.
- the admission valve AV must vary its opening degree of about 80% (100% - 20%), while the by-pass valve BV will vary its opening degree of only 30%. Furthermore, during the adjustment the two valves cannot move independently, otherwise there would be times when the invariance of the total flow rate would not be respected. In other words, the function between %BV and %AV shown in Fig. 4 has always to be respected in each instant of the transient. Transient which is not temporally negligible, since both valves AV, BV are normally moved by pneumatic actuators which have a relatively low speed (when compared with the speed of equivalent hydraulic actuators) typically comprised between 25 and 10 percentage points of the opening degree per second (the larger the valve, less quickly it can be adjusted).
- the by-pass valve BV may reach the target in 3 seconds, while the admission valve AV in 8 seconds; then the position of the by-pass valve BV must be continuously modulated (slowed down) until the admission valve AV has reached the required position, respecting the constancy of the flow rate, as in Fig. 4.
- the slowest valve and/or the one that must change more the opening degree establishes the overall speed with which both valves will arrives to the final position, passing from intermediate positions that realize the constancy of the flow rate.
- the present methodology can be implemented also using for a finer adjustment a controller of proportional- integral-derivative PID type, as shown in the block diagram of Fig. 6.
- the PID controller determines S620 the theoretical value of the opening degree %AV. Whereas the valve speed is relatively low (especially for large valves), the opening degree required at time t + 1 is corrected S630 by taking into account said speed limit. Finally, according to the effective opening degree %AV, the transmitted power is measured S640, and this is the value of the control feedback.
- the bypass valve BV assumes instant by instant the opening degree value calculated in S650 as a function of the relationship S520 that links the opening degree %BV with the opening degree %AV.
- the opening degree required at time t + 1 is corrected S660 by taking into account the speed limit of the valve movement. More in particular, the positions of the AV and BV valves are modulated so as to ensure that the various opening degrees %AV, %BV of the valves (which have been obtained during movements of the same valves) realize the substantial constancy of the total flow rate. This means that one of the two valves will have to "wait" for the other in order to ensure the above mentioned principle.
- Fig. 5 and 6 can be used individually or in combination.
- the admission valve AV and by-pass valve BV are moved toward the positions calculated using the logic of Fig. 5 and, once reached the calculated position, their final positions will be corrected using the PID controller, according to the logic of Fig. 6.
- the proposed methodology defines a relatively simple mode for controlling the power delivered by the ORC power plant, without modifying the thermodynamic cycle.
