Description

Device for configuring a multivalent energy supply

Technical Field

The utility model relates to a device for configuring a multivalent energy supply.

Background

A method for operating a system having a plurality of heat generating devices is known, for example, from EP 2187136 a 2. The system may provide thermal power using a plurality of heat generating devices, wherein the distribution of thermal power to the individual heat generating devices is variable such that the heat generating devices may be operated near their optimal efficiency. The distribution of power can take place not only via the superordinate boiler management system but also via the mutual coordination of the individual heat generation devices.

A mobile heating system is known from international patent application WO 2009/141176 a1, which has a plurality of fuel-operated heating devices, which are connected to one another in a communication manner via a bus system. The heating system is configured such that, when the heating system is started, one of the heating devices is configured as a Master device (Master) on the basis of predetermined rules for operating the other heating devices connected to the bus system. The remaining heating devices are configured as Slave devices (Slave).

A hybrid heating system consisting of at least one condensing boiler (Brennwertkessel) and at least one non-condensing boiler is known from international patent application WO 2008/091970 a 2. After the heating load has been determined, the individual boilers are switched on or off by the control device, in particular depending on the flow in the main circuit of the heating system and other start-up criteria. The boiler is also selected according to the outside temperature and the operating time of the respective boiler.

SUMMERY OF THE UTILITY MODEL

The object on which the utility model is based is to specify an apparatus for configuring a multivalent energy supply. Such an apparatus would be improved, inter alia, in such a way that a large number of different device configurations can be created.

This object is achieved by providing a device for configuring a multivalent energy generating means, wherein the device comprises a storage means in which a basic configuration system is stored. The basic configuration system is a schematic of the general infrastructure of the multivalent energy supply. The basic configuration system comprises placeholders (Platzhalter) for possible components of the energy supply device and their relationship to one another. The basic configuration system comprises in particular a plurality of energy generators which use at least two different energy carriers in order to provide energy in the form of thermal energy and/or cold energy and/or electrical energy.

By replacing placeholders with components that are actually present in the multivalent energy generating device, the basic configuration system can be matched to the actually present or planned device configuration. The result of the adaptation can be, for example, a device configuration in the form of a hydraulic diagram of the heating device and/or a block diagram of the multivalent energy generating device, which shows the relationships between the individual components and/or their functions and/or their effects in a graphical manner. The hydraulic schematic and/or block diagram may be used to configure a control device for controlling the multivalent energy generating device. The storage device may be configured to store the hydraulic schematic or block diagram. Furthermore, the device may be configured and adapted to transmit the hydraulic diagram or block diagram to a control device for controlling the multivalent energy generating device, for example via a suitable data communication connection.

The device for configuring the multivalent energy supply apparatus may be realized as an electronic data processing device, such as a computer, a tablet computer, a smartphone, a portable computer or some other electronic control device, in particular an electronic control device with a microprocessor. The means for configuring may be configured to be adapted to communicate with a control device for controlling the multivalent energy generating device. The device can also be implemented as part of a control device for controlling the multivalent energy generating device. The device for configuring is configured to be suitable for transmitting the basic configuration system or a specific device configuration generated by the basic configuration system into the control device, so that the control device can control the energy generator depending on its detected type and position in the basic configuration system or the generated device configuration.

A control device designed to be configured according to the basic configuration system according to the utility model can control a plurality of multivalent energy generating devices and can be adapted to changing device configurations by simply adding or removing individual components.

The basic configuration system also comprises a forward flow line (Vorlauf) through which flows a carrier medium which absorbs the energy of the energy generator and transmits it to the consumer circuit. The load circuit may comprise a plurality of different and/or identical types of loads. The consumer may be any energy consuming device, such as a heating body.

In the case of a heating system, the forward flow circuit can be embodied as a pipe circuit (Rohrleitung) in which a fluid carrier medium flows, which carrier medium absorbs heat embodied as an energy generator for heating the boiler. In the case of an electrical energy generator, the forward flow lines are the following electrical lines: in which electrical energy flows in the form of electric current. The charge carriers in the electrical lines can then be correspondingly understood as carrier media.

The basic configuration system also comprises a return line (rucklauf) which conveys the carrier medium from the consumer circuit back to the energy generator. As in the forward flow line, in the case of a heating system, the return line may be a conduit line as follows: in this line, the fluid carrier medium flows back from the consumer circuit into the production circuit. Accordingly, in the case of an electrical energy generator, the return line is an electrical line as follows: this electrical line completes the current circuit from the consumer to the energy generator. Since this can also be effected via ground potential, a direct conductor connection is not required in this case as a return line between the load and the energy generator.

The basic configuration system also comprises a buffer storage for intermediate storage of energy in the form of thermal and/or cold energy and/or electrical energy (for example in the form of an electrical charge). The buffer store may be, for example, a hot water store, a battery, an accumulator, or a capacitor. The buffer store is connected to the forward flow line in order to be able to absorb energy. Furthermore, the buffer memory may be connected to a return line. Energy transfer occurs through the forward flow line. The call for energy of the buffer memory (Abrufen) can also be made via the frontstream line. For this purpose, the buffer memory can have a valve or a switch, by means of which the energy supply and the energy retrieval can be adjusted accordingly.

The first energy transfer device may be arranged in a basic configuration system. The energy transfer device is preferably arranged downstream in the upstream line with respect to the buffer store. The term "downstream" here refers to the direction of flow of the carrier medium from the energy generator to the consumer circuit. The energy exchange between the generator circuit (primary side) and the consumer circuit (secondary side) can take place in the energy transmission device. The energy transmission device may also be additionally arranged in the return line.

The energy transfer device may be a heat transfer device as follows: in which heat is transferred from the carrier medium (primary side) of the generator circuit to the carrier medium (secondary side) of the consumer circuit. The two circuits are usually separate so that the carrier media do not mix. The heat transfer takes place via a material which is particularly thermally conductive.

By using the energy transmission means, a direct exchange of the carrier medium between the generator circuit and the consumer circuit can be avoided. Thus, there is only an energy transfer, but no material transfer from the carrier medium on the generator side (primary side) to the carrier medium on the consumer side (secondary side).

Within the basic configuration system, the energy generator is arranged in parallel with the buffer memory in different positions between the forward flow line and the return line. The energy generators may be arranged on both sides of the buffer storage, i.e. upstream and/or downstream of the forward flow line. Furthermore, the energy generators may be arranged in series in the forward flow line. The energy generator can be arranged in particular in the upstream line between the buffer store and the first energy transmission device. The energy generator arranged in series can, for example, increase the energy content of the carrier medium from the buffer store without mixing in a certain amount of the carrier medium from the return line.

The actual hydraulic diagram or the actual infrastructure structure of the multivalent energy supply device can be determined from the basic configuration system by selecting components. Each optional component herein also includes information about its function and effect. The basic configuration system and hydraulic schematic or block diagram also graphically illustrate the relationship, e.g., hydraulic connections, between the various components.

The control of multivalent energy supply devices can be very complex and often requires a matched customized (ma β geschneidert) solution. Depending on the complexity of the energy supply device, the development effort and associated costs for providing system control may yield high results (ausfallen). On the other hand, when installing the energy supply device, the configuration of the respective control device may be very complicated and time consuming. It is therefore an object of the present invention to provide an apparatus which allows a plurality of different multivalent energy supply devices to be configured according to a basic configuration system. The basic configuration system may represent the relationship, function, and effect of a number of components. The control device may be configured based on the basic configuration system to control the multivalent energy supply device.

A multivalent energy supply device is an energy supply device that uses a plurality of energy carriers as energy sources. It has at least two energy generators, each of which provides a usable energy form, for example thermal energy, cold energy, mechanical energy and/or electrical energy (for example electrical current and/or voltage). The thermal energy can be provided, for example, to a hot water supply and/or to a heating device and/or as process thermal energy, for example, to an industrial application. A fluid carrier medium, i.e. a gas or a liquid (e.g. water or water vapour), is usually used to transport the heat.

In order to operate the multivalent energy supply device optimally, the energy supply device must be controlled according to the specific characteristics of the energy generator, which depend in particular on the type of energy carrier used. The present invention is directed to combining these specific characteristics with each other in a synergistic manner. In other words, the method according to the utility model allows the respective advantages of different energy carriers to be optimally combined with each other. This is achieved by the coordinated control of the energy generators, so that additional benefits can be obtained from the multivalence of the energy supply. In particular, a combination of renewable energy carriers and fossil energy carriers can be used in this case, so that at the same time a particularly efficient and economical operation of the energy supply device is achieved with reliable energy supply. The energy supply control is also intended to be able to react to changing conditions. For example, strong fluctuations in the availability of one of the used energy carriers can be compensated for by using at least one second energy carrier which is available at any time.

The at least two energy generators of the multivalent energy supply use at least two different energy carriers. For example, fossil energy carriers and/or renewable energy carriers can be used as energy carriers. For example, two or more of the following lists may be used: coal, natural gas, fuel oil, diesel, gasoline, hydrogen, biogas, wood (e.g., granular) or other types of biomass, geothermal energy, solar radiation, wind, electrical energy (e.g., current and/or voltage), remote heating, mechanical energy (e.g., hydraulic).

The multivalent energy supply device according to the utility model has at least two energy generators, for example two or more of the following list: oil fired boilers, gas fired boilers, condensing boilers, thermal power stations (BHKW for short), wood boilers, heat pumps, photovoltaic systems, wind turbines, solar collectors, fuel cells. Furthermore, a thermal coupling to a stirling engine can be realized, for example.

When different energy generators are operated in a multivalent energy supply, they may have very different characteristics and thus different or even opposite requirements. Exemplary features of some selected energy generators are described below.

Oil or gas fired boilers use fossil energy (oil or gas) and provide heat, which is typically transferred to a fluid carrier medium, typically water. It can provide high power in a short time and also can be quickly turned off. Such a boiler is easy to adjust and can therefore be used in a modulating operation. The boiler also allows frequent switching on and off, and can therefore also be used in two stages in on/off operation. Oil-fired and gas-fired boilers can therefore be used particularly flexibly in their operation and are frequently used as so-called peak-load boilers which should react quickly to fluctuations in the energy supply requirement.

Thermal power plants (BHKW) typically use fossil fuels, but can also be operated using biogas or hydrogen from renewable resources. It supplies heat and electrical energy (current and/or voltage), is easy to regulate and can be rapidly raised (hochfahren) to high power and also rapidly lowered again (runterfahren). The difference with the boiler is that the BHKW should not be switched on or off as often. To run BHKW economically, it is typically used in continuous operation.

Wood boilers use solid fuel from renewable energy sources (wood, e.g., in the form of pellets (Pellet) or wood chips (Hackschnitzel)) and provide heat. It can only be adjusted moderately and can only be raised to high power or lowered again relatively slowly. Due to the long on-time, the wood boiler should not be switched on or off as often. At shutdown, it is often necessary, for safety reasons, to wait until the fuel already present in the combustion chamber has completely burnt out. On the other hand, when switching on, sufficient fuel must first be delivered into the combustion chamber and ignited. This results in a relatively low overall energy cost. This is why it is used primarily as a base-load boiler which is to be operated as continuously as possible and which can meet the lowest energy requirements of the energy supply.

In order to be able to react to fluctuations in the required amount of energy (energy), it is customary to use a wood boiler in conjunction with a buffer store which stores the heat supplied by the wood boiler in the interim if the heat required by the electrical consumers is less than the heat supplied by the wood boiler. If the consumer requires more heat than is supplied by the wood boiler, the stored heat can first be discharged from the buffer store. As an alternative or in addition to the buffer store, a gas boiler is often used together with a wood boiler in the energy supply. When the required heat exceeds that available from the wood boiler and the buffer store, the gas boiler is switched on. The gas boiler is used as a peak load boiler.

The electric heat pump consumes electric energy, and thus uses fossil energy and/or renewable energy according to from which source electric energy is taken. Electric heat pumps can provide heat and/or cold energy, but have a limited temperature range. Typically, heat pumps can provide a front stream temperature of up to 60 ℃. The electric heat pump is easy to regulate and can be quickly raised to high power or quickly lowered again. However, it is not allowed to switch the electric heat pump on or off frequently. The electric heat pump incurs a relatively low total energy cost.

Another component used in multiple multivalent energy supplies is a buffer storage. The buffer store can store the energy supplied by the energy generator in the interim in time. Depending on the energy form, the buffer store can be, for example, a store for electrical energy, for example in the form of a battery or a capacitor, or a hot and/or cold store, for example in the form of an insulated water tank. Furthermore, the energy can also be stored in the form of mechanical energy, for example in a flywheel. The buffer memory allows the operation of the energy generator to be at least partially decoupled from the energy consumer. The efficiency of the multivalent energy supply device can thereby be improved.

In a multivalent energy supply, it is also possible to provide an energy generator which can simultaneously provide more than one form of energy. Depending on the requirements, it may be necessary to determine under which preconditions such an energy generator is switched and/or regulated. By means of a hydraulic diagram or block diagram, the control device can determine which energy generators can be or should be switched on depending on which criteria. Furthermore, the hydraulic diagram or block diagram can indicate which type of energy generator is present in the energy supply device. Additionally, the control device receives information about the respective properties of the energy generators, which information has been described in detail for some energy generators by way of example.

Furthermore, the hydraulic diagram or block diagram may contain information about the controllable devices of the assembly. For example, the energy generator may include one or more of the following listed devices: temperature sensors, current sensors (volume flow and/or current), circulation pumps, generator pumps, valves, backflow mixers, pre-flow mixers, bypasses, throttle valves.

Furthermore, valves, temperature sensors, current measuring devices (for measuring the current or for measuring the volume flow), voltage measuring devices (for measuring the voltage), diodes, safety devices and/or other components which can be set by the control device or provide information about the operating state to the control device can be arranged in the forward flow line and/or the return flow line. The hydraulic diagram or block diagram obtained from the basic configuration system also includes the positions of the respective components, so that the control device can determine the desired value for the energy generator, for example, for the device upstream line temperature required at a specific location in the energy supply device, in order to meet the requirements.

BHKW may provide not only thermal energy but also electrical energy (current and/or voltage). Thus, for BHKW, there may be two different requirements from the two energy forms. The electrical energy provided by the BHKW can be fed into the public power grid at any time if there is no corresponding demand from the consumers supplied by the multivalent energy supply. The device configuration for this purpose also comprises information about the energy transfer to the public electricity network.

Each energy generator in the energy supply device has a control device for controlling a state variable of the energy generator. State variables of the energy generator include, for example, the boiler temperature of the energy generator, the volumetric and/or mass flow of the carrier medium through the energy generator, the temperature of the carrier medium in the feed line and/or return line, the power absorption of the energy generator and/or the power output of the energy generator. In the case of an energy generator which supplies electrical energy, the state variables can relate to current, electrical power and/or voltage.

The regulating device is coordinated by a control device which is (u bergeordnet) higher in class than the regulating device. The control device is configured and adapted to detect an energy supply request for energy in the form of thermal energy and/or cold energy and/or electrical energy. The energy supply requirement can be, for example, a requirement for a specific forward flow temperature at a predetermined point in the hydraulic diagram, or a specific temperature in the buffer store, in particular in a specific region of the buffer store, or an electrical power at the energy transmission device. The energy supply requirement can be generated, for example, by a consumer or a combination of consumers (Verbund) and output to the control device via a suitable data communication link. By using a hydraulic diagram or block diagram configured, the control device finds out at which position which energy generator or which buffer store can be used to meet the energy supply requirement.

Advantageous configurations and embodiments which can be used individually or in combination with one another are preferred embodiments.

A preferred basic configuration system has at least two energy generators which are arranged in parallel with one another between the forward flow line and the return line.

At least two energy generators may be arranged upstream in the upstream line with respect to the buffer store. Here, "upstream" means in particular with respect to a line of pipes in which the liquid carrier medium flows counter to the flow direction. "downstream" accordingly means in the direction of flow of the carrier medium. In principle, the number of energy generators can be arbitrarily high.

In a preferred basic configuration system, at least one energy generator is arranged downstream in the upstream line with respect to the buffer store. The energy provided by the energy generator can therefore optionally not be stored in a buffer store, but can always flow directly to the consumer via the upstream line. Such an energy generator downstream of the buffer store can be used, for example, in a heating system to raise the temperature of the front stream of carrier medium coming from the buffer store to a higher temperature when required.

In the basic configuration, at least one primary-side energy transfer device is arranged in parallel with the first energy transfer device upstream of the first energy transfer device in the upstream circuit and/or at least one secondary-side energy transfer device is arranged in parallel with the first energy transfer device downstream of the first energy transfer device in the upstream circuit. The primary-side and secondary-side energy transmission devices can supply energy to further load circuits that are each independent of one another.

In the basic configuration system, at least one primary-side buffer memory is arranged upstream of the aforementioned buffer memory in the upstream line in parallel with the aforementioned buffer memory and/or at least one secondary-side buffer memory is arranged downstream of the aforementioned buffer memory in the upstream line in parallel with the aforementioned buffer memory.

The at least one energy generator may be arranged in series in the feed-forward line between the buffer store and the energy transmission device. The energy generator arranged in series can be, for example, a gas boiler, which can directly increase the temperature of the feed stream without mixing in a certain amount of carrier medium from the return line. Such series-connected boilers can therefore be operated as continuous heaters (Durchlauferhitzer).

To this end, the detection means may be configured and adapted to detect one type from a predetermined number of buffer memory types for each of the buffer memories. In particular, the type of energy stored is detected. Furthermore, a specific embodiment of such a buffer memory may be selected, for example, from a list. For this purpose, functional details of the buffer memory may be stored. A possible alternative buffer memory type could also be a simple direct connection as follows: the simple direct connection is selected if there is no buffer memory in the corresponding location (the aforementioned buffer memory, on the primary side, on the secondary side). Furthermore, buffer memories with or without a mixing pump, with or without a return line mixer, with or without a buffer release valve (pushertlayvetentil), with or without a buffer release pump (pushertlaydepumpe) and/or with or without a temperature sensor can be selected or detected.

The detection means may be further configured and adapted to detect one type from a predetermined number of energy transfer types for each of the energy transfer means. In this case, it is detected which energy type is transmitted. Furthermore, a specific implementation of such a component may be selected, for example, from a list. For this purpose, functional details of the components can also be stored. An alternative possible type of energy transmission device can also be a simple direct connection, which is selected if there is no energy transmission device at the respective location. Furthermore, energy transfer devices with or without a forward flow pump, with or without a device mixer, with or without a heat exchanger, and/or with or without a hydraulic separator (hydraulische Weiche) may be selected or tested.

Detailed Description

In the following description of the preferred embodiments of the utility model, like reference numerals designate identical or comparable components.

First embodiment

Fig. 1 shows a basic configuration system BK according to a first embodiment. The basic configuration system BK comprises six energy generators E1.. E6, three buffer storages P, PP, PS and three energy transfer devices

Which are arranged on the forward line V and the return line R, respectively. The energy generators E5, E6 in series are not directly connected to the return line. The number of energy generators can be expanded at will, which is indicated by dots in the illustration of the forward line and return line.

In order to configure a specific infrastructure of the multivalent energy supply device, the apparatus according to the utility model comprises a detection device. The device may be, for example, a computer, tablet, smartphone, or other device having a graphical user interface. The basic configuration system BK is stored in a memory of the device. From which the basic configuration system BK can be loaded. A graphical representation of the basic configuration system BK may be displayed in a menu. By clicking or touching, an installer or other user can select a specific embodiment for each of the components from a list or graphical representation of the components in a menu navigation (Men ü fuhrung).

By selecting the component, the user passes the configuration of the actual implementation of the energy supply device into the graphical representation of the device configuration. The resulting device configuration may be a hydraulic schematic or block diagram of the energy supply device. The relationships between the components and information about their functions and effects are represented by the device configuration and can be detected by it through the control device.

The buffer storage P is further downstream in the forward flow line V in parallel with the first gas boiler G1 and BHKW B1, B2. Downstream of the buffer store P, a second gas boiler G2 is arranged in series in the forward flow line V, so that the second gas boiler G2 can directly increase the forward flow line temperature. Since the second gas boiler G2 is arranged after the buffer storage in the forward flow line, the second gas boiler cannot influence the temperature of the water stored in the buffer storage.

Starting from the basic configuration system BK of fig. 1, the hydraulic diagram of the third embodiment is configured in the following manner: two wood boilers H1, H2 in parallel with the buffer store P are selected instead of the first energy generators E1, E2. The primary-side buffer memory PP and the secondary-side buffer memory PS are respectively configured to be directly connected. At a point E5 in fig. 1, the gas boiler G1 is selected as the first energy producer in series, and E6 is configured to be directly connected. The energy transfer device is also configured for direct connection.

Configured as a heat transfer device

Sixth embodiment

Fig. 6 shows a hydraulic diagram of a multivalent energy supply according to a sixth embodiment. The energy supply device comprises two gas boilers G1, G2, two BKHW B1, B2 and two wood boilers H1, H2 and a buffer store P. Furthermore, a temperature sensor T1 is arranged in the upstream line V, which measures the energy supply device upstream line temperature. Three temperature sensors T2, T3, T4 are arranged in the buffer memory P, which temperature sensors measure the temperature in the buffer memory P, respectively in the upper, middle and lower regions of the buffer memory.

Starting from the basic configuration system BK of fig. 1, the hydraulic diagram of the sixth embodiment is configured in the following manner: two gas boilers G1, G2, two BKHW B1, B2 and two wood boilers H1, H2 were selected instead of the first energy generators E1, E2. The buffer memory P is configured as a buffer memory having four temperature sensors T1 to T4. The primary-side buffer memory PP and the secondary-side buffer memory PS are respectively configured to be directly connected. The series-connected energy generators E5 and E6 are also configured to be directly connected.

Controlling the energy supply device in accordance with the detected configuration. All six energy generators can be heated directly on the upstream line or buffer. Since all energy generators are connected in parallel, they can operate independently of each other.

The control device may be predefined in that a large amount of energy is to be stored in the buffer memory P. From the hydraulic diagram, the control device recognizes that all energy generators can be used to store thermal energy. Furthermore, the control device recognizes that the buffer temperature sensor T4 in the lower region of the buffer memory P can be selected for buffer temperature adjustment. For this purpose, the desired buffer temperature is set to 70 ℃, for example. The control means S then ensure that the buffer memory P is completely charged at a temperature of 70 ℃.

If the buffer memory P stores only about half, the buffer temperature sensor T3 in the middle area of the buffer memory P is selected for buffer temperature control.

If the buffer storage is not required, the buffer temperature sensor T2 in the upper region of the buffer memory P is selected for buffer temperature adjustment. The buffer setpoint temperature need not be predefined, since the desired temperature of the power generator upstream line can be calculated from the desired temperature of the device upstream line. Only as much energy as is received by the consumer is produced, in which case the buffer store P is not charged. The system forward line temperature may be measured, for example, by a temperature sensor T1 on the forward line V.

The features disclosed in the foregoing description, the claims and the drawings may be important for the implementation of the utility model in its different configurations, both individually and in any combination.
