Abstract

Elektrische Schaltung (4+5+17) zur möglichen Eigenstrom Nutzung für Verbraucher unterschiedlicher Tarifstellung dadurch gekennzeichnet, dass ein Verbraucher in Abhängigkeit der vom Generator (6+7) zur Verfügung gestellten Leistung nicht mehr über die dafür vorgesehene Messeinrichtung (3) versorgt wird, sondern über jene Messeinrichtung (1), ggf. auch nur teilweise (1+2), über welche die erzeugte Strommenge (1) erfasst wird.Electrical circuit (4 + 5 + 17) for possible own power use for consumers of different tariff position, characterized in that a consumer depending on the power provided by the generator (6 + 7) is no longer supplied via the dedicated measuring device (3), but via those measuring device (1), possibly also only partially (1 + 2), via which the amount of electricity generated (1) is detected.

Description

Für größere elektrische Verbraucher stellen Energieversorgungsunternehmen unterschiedliche, meist monetär günstigere, Tarife zur Verfügung. Derzeit werden für diese größeren Verbraucher eigene Zählwerke [siehe in A(3)] installiert. Die Erfindung soll am Beispiel eines Einfamilienhauses mit haushaltsüblichen Verbrauchern [z. B. Waschmaschine: A(12), Fernseher: A(11), Steckdose: A(10), Backofen: A(9)] und einem größeren elektrischen Verbraucher [z. B. Wärmepumpe: A(8)], für welchen eine gesonderte Tarifstellung und demnach auch Leistungsmessung gilt, beschrieben werden. Für den Haushalt findet eine eigene Messung satt, siehe A(2). Wird nun ein Stromerzeuger [beispielweise Photovoltaik: A (6+7) oder Blockheizkraftwerk] errichtet und möchte der Nutzer den erzeugten Strom selbst verbrauchen, so wird das Haushaltszählwerk A(2) als sog. „2-Richtungszähler” ausgeführt. Das Zählwerk A(1) erfasst die erzeugte Strommenge. Derzeit wird der Haushaltszähler A(2) als „2-Richtungszähler” ausgeführt, da über die haushaltsüblichen Verbraucher schon bei einer geringen Leistung des Generators der selbst erzeugte Strom genutzt werden kann.For larger electrical consumers provide energy companies different, usually cheaper monetary tariffs available. Currently, for these larger consumers own counters [see A ( 3 )] Installed. The invention is based on the example of a single-family home with household consumers [z. B. Washing machine: A ( 12 ), TV: A ( 11 ), Socket: A ( 10 ), Oven: A ( 9 )] and a larger electrical consumer [z. Eg heat pump: A ( 8th )], for which a separate tariff position and therefore also performance measurement applies. For the household finds its own measurement tired, see A ( 2 ). Will now a generator [for example photovoltaic: A ( 6 + 7 ) or cogeneration plant] and the user wants to consume the generated electricity itself, then the household counter A ( 2 ) as so-called "2-direction counter" executed. The counter A ( 1 ) records the amount of electricity generated. Currently the household counter A ( 2 ) as a "2-directional counter" executed, as can be used on the household consumers even at a low power of the generator of self-generated electricity.

Möchte ein Nutzer jedoch auch mit seinem größeren Verbraucher den eigens erzeugten Strom nutzen, so ist dies aufgrund der ausgeführten Hausinstallation [siehe Leitungsführung A (13+14+15+16)] und aufgrund der unterschiedlichen Messung (3) und (2) nicht möglich. Dies ist momentan nur möglich, wenn der Großverbraucher über die Hausinstallation und damit zu höheren Tarifen versorgt wird. Der Nutzer ist jedoch aus wirtschaftlichen Gründen bestrebt, möglichst viel Strom selbst zu verbrauchen und so wenig wie möglich über das Energieversorgungsunternehmen zukaufen zu müssen.However, if a user would like to use the electricity generated specifically with his larger consumer, this is due to the house installation carried out [see Wiring A ( 13 + 14 + 15 + 16 )] and due to the different measurements ( 3 ) and ( 2 ) not possible. This is currently only possible if the bulk consumer is supplied via the house installation and thus to higher tariffs. For economic reasons, however, the user endeavors to consume as much power as possible and to purchase as little as possible from the energy supply company.

Die Erfindung in A (4+5+17), als gestrichelte Linien dargestellt, nach Schutzanspruch 1 löst dieses Problem. Durch das elektrische Trennen des Großverbrauchers vom Zählwerk (3) [zum Beispiel durch einen Öffner Schütz A(4)] und der Herstellung einer elektrischen Verbindung A(17) [zum Beispiel durch einen Schließer Schütz A(5)] zur Hausinstallation kann sich der Großverbraucher (8) vom selbst erzeugten Strom „bedienen”. Das Aktivieren dieser Schaltung erfolgt in Abhängigkeit der vom Generator (6+7) zur Verfügung gestellten Leistung, wobei unerheblich ist, an welcher Stelle vom Generator zum 2-Richtungszähler (2) diese Leistung gemessen wird. Ein Signalgeber könnte wie in A dargestellt, zum Beispiel der Wechselrichter (7) einer Photovoltaikanlage sein. Die Erfindung kann sich nach Schutzanspruch 3 als fertige Baugruppe mit entsprechenden Aktoren oder nach Schutzanspruch 2 als Einzelkomponenten zeigen. Die Erfindung kann in der Hausinstallation, im Großverbraucher, im Generator oder unmittelbar vor oder nach einem Zählwerk verbaut sein.The invention in A ( 4 + 5 + 17 ), shown as dashed lines, according to protection claim 1 solves this problem. By electrically disconnecting the large consumer from the counter ( 3 ) [for example by a normally closed contactor A ( 4 )] and the production of an electrical connection A ( 17 ) [for example by a normally open contactor A ( 5 )] for domestic installation, the bulk consumer ( 8th ) "operate" from self-generated electricity. The activation of this circuit takes place in dependence of the generator ( 6 + 7 ), whereby it is irrelevant at which point from the generator to the 2-direction counter ( 2 ) this power is measured. A signaler could be as in A represented, for example, the inverter ( 7 ) be a photovoltaic system. The invention may be according to protection claim 3 show as a finished assembly with corresponding actuators or protection claim 2 as individual components. The invention can be installed in the house installation, in large consumers, in the generator or immediately before or after a counter.

Die mit dieser Erfindung erzielten Vorteile sind, dass

  • – sowohl Groß- und/oder Kleinverbraucher mit eigens erzeugtem Strom versorgt werden können
  • – der Eigenstromverbrauch erhöht werden kann
  • – tarifbedingte Sperrzeiten der Großverbraucher umgangen werden können, sowie genug Eigenstrom zur Verfügung steht
  • – der Nutzer einen monetären Vorteil gegenüber der bisherigen elektrischen Ausführung hat
  • – die Netze des EVUs infolge des Eigenstromverbrauchs entlastet werden
  • – der Eigenstromverbrauch der Netzstabilität dient und der „50,2 Hertz-Problematik” entgegenwirkt
  • – diese Schaltung unter Umständen vom örtlichen Elektriker ausgeführt werden kann, da sie „nach” den Zählwerken des EVUs errichtet wird
  • – diese Schaltung auch bei bestehenden Anlagen nachgerüstet werden kann
The advantages achieved by this invention are that
  • - Both large and / or small consumers can be supplied with self-generated electricity
  • - The own power consumption can be increased
  • - Tariff-related blocking periods of bulk consumers can be bypassed, and enough own electricity is available
  • - The user has a monetary advantage over the previous electrical design
  • - the networks of the RUs are relieved as a result of own electricity consumption
  • - The own power consumption of grid stability serves and counteracts the "50.2 Hertz problem"
  • - this circuit may be carried out by the local electrician, as it will be built "after" the utility's meters
  • - This circuit can be retrofitted to existing systems
