Definitions
- Gas quality in a gas network section for controlling consumers and/or producers in the gas network section, the gas quality for the gas network section being able to be determined in real time in a simple manner and the regulation of the consumers and/or producers in the gas network section being able to be adapted thereto.
- One object of the invention is to provide a method and a system which makes it possible to determine a gas quality, in particular with regard to the concentration of an additional gas and/or a calorific value, in a gas network section in a simple manner in real time and to control consumers and /or adapt producers in the gas network section to the determined gas quality.
- additional gases can have a major impact on the quality of the gas in the gas network and thus also on the operation of devices, i.e. consumers and generators, such as gas burners, fuel cell modules and electrolysers.
- the proportion of an additional gas in the fuel gas can vary both regionally and time-dependent in gas network sections.
- EP 2 450 704 B1 describes a method for determining the calorific value of fuel gas, in particular natural gas, in gas networks, in particular in regional or distribution networks with at least two feed points, a plurality of network nodes and a number of exit points, where a) the calorific values and quantities are measured at the entry points of the gas network, b) the quantities at the exit points of the gas network are estimated and totaled on the basis of load profiles according to corresponding equations, c) the values determined in each case are fed to an evaluation unit together with topological data of the gas network and the calorific values at at least one exit point can be determined by calculation.
- EP 3 287 750 B1 describes a gas meter system and a calorific value estimation method.
- the gas meter system is configured to estimate a calorific value of a gas that passes through a first gas meter and to estimate a calorific value of a gas that passes through a second gas meter provided separately from the first gas meter.
- the estimation is based on the calorific value of the gas of the first gas meter, which is arranged along a gas supply line at a predetermined distance with respect to the second gas meter.
- DE 10 2018 106 576 A1 describes a method for determining gas consumption when the gas quality in a gas network changes, with at least one meter device for recording at least one gas volume flow, with one or more local gas feed points being provided in the gas network.
- At least one current gas quality is determined in a network section of the gas network, with at least one consumption point in the network section taking a gas volume flow.
- At least the current gas quality of the gas in the network section is transmitted to a data center.
- a consumption of the gas volume flow of the at least one consumption point is determined with its counter device.
- the current consumption is transmitted to the data center using time-precise meter readings from the meter device.
- the current calorific value is determined based on the gas quality in the network section and at least the timely calorific values are linked to the meter readings at the consumption point.
- the FR 3 030 034 Al describes, for example, a gas meter for customer installation of a gas distribution network, comprising a line with a gas inlet opening and a gas outlet opening, a unit for measuring in the line, an analysis unit for the gas flowing in the duct in order to determine at least a partial composition thereof, and a data transmission unit which is connected to the analysis unit and arranged to transmit an identifier and analysis data, and at least one data acquisition unit separate from the measuring device .
- a method according to the invention for determining a gas quality in a gas network section for controlling consumers and/or producers in the gas network section comprises the step a) of determining a gas quality by at least one consumer or at least one producer in the gas network section.
- consumer and producer refer to the consumption of gas from a gas network section, or correspondingly to the generation of gas. Consumers can therefore be gas burners or fuel cell modules, for example, while producers can be electrolysers or modules for methanation, for example.
- device refers to both a consumer and a generator.
- the gas quality in step a) is determined directly by the at least one consumer or the at least one producer using internal measuring sensors.
- the operating state in which the gas quality is determined by the at least one consumer or the at least one producer is not restricted according to the invention.
- the gas quality can be determined in a calibration mode, for example. In a preferred embodiment, however, the gas quality can be determined in step a) during operation of the at least one consumer or the at least one producer.
- the method for determining the gas quality is not restricted according to the invention and will depend on the type and configuration of the at least one consumer or the at least one producer.
- the gas quality can be determined, for example, by determining a flame temperature.
- the flame temperature can be determined, for example, using the glow-electric effect on the ignition electrode (temperature of the flame on the ignition electrode), as described in EP 2 549 187 B1, for example.
- the method according to the invention makes it possible to dispense with additional measuring points and measuring devices for determining a gas quality in a gas network section.
- gas quality is to be interpreted broadly herein.
- gas quality can refer to all properties of the gas carried in a gas network section.
- the determination of the gas quality in step a) can in particular include the determination of a concentration of an additional gas and/or the determination of a calorific value.
- additional gas refers here to any proportionate, gaseous admixture to the basic gas (natural gas) carried in a gas network section.
- additional gas is not restricted according to the invention.

- the additional gas can be, in particular, hydrogen.
- the method according to the invention also includes step b) of transmitting the gas quality determined in step a) and position data of the at least one consumer or of the at least one producer in real time to a central unit.
- Real time means the time delay that occurs between the transmission of the gas quality to the central unit and the gas quality being output to at least one further consumer or at least one further producer is in the gas network section, so that the at least one further consumer or at least one further producer can be regulated based on the gas quality output by the central unit.
- Central entity herein means an entity for the transmission (transmission and reception), storage and processing of data.
- a central unit can, for example, be a control room, a server or a cloud. Consumers and/or producers in a gas network section can advantageously form a network with the central unit. Alternatively, or in addition to this, a central unit can also be connected to a number of networks or clusters of consumers and/or producers. The networks or clusters can be assigned to different, regionally specific gas network sections, for example.
- position data of the at least one consumer or at least one producer are also transmitted to the central unit in step b) of the method according to the invention.
- the position data can be anonymized. Anonymized can mean, for example, that only the assignment of a gas connection to an area of the gas network section is transmitted as position data.
- the method according to the invention also includes step c) of determining the gas quality in the gas network section by the central unit based on the transmitted gas quality and the position data. This can be done, for example, by linking the gas quality determined by the at least one consumer or the at least one producer with the transmitted position data.

- An average gas quality in the gas network section can then be determined in step S103 from the transmitted gas properties and position data.
- the method can then additionally include the step: determining a difference in the gas properties transmitted in step S102 using a specified limit value and, if the specified limit value is exceeded or undershot, outputting an error message to the relevant consumer or producer.
- the specified limit value can preferably specify a maximum deviation of 10% between the transmitted gas properties, particularly preferably 5%.
- the gas quality can also be output to two or more other consumers or producers in the gas network section in step S104, in which case the regulations of the two or more consumers or producers in the gas network section are adjusted based on the output gas quality in step S105 be able.
