Description

Die Erfindung bezieht sich auf eine Steueranordnung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a control arrangement according to the preamble of patent claim 1.

Solche Steueranordnungen sind bekannt. Elektrische Energie ist nicht direkt speicherfähig, so daß die jeweils benötigte Energie zur gleichen Zeit in den Kraftwerken erzeugt werden muß. Elektrische Kraftwerke, insbesondere Kernkraftwerke, arbeiten am wirtschaftlichsten, wenn die Leistungsabgabe möglichst konstant ist. Dem steht jedoch der stark schwankende Leistungsbedarf während des Verlaufes eines Tages entgegen. Um einen gleichmäßigeren Verlauf des Leistungsbedarfes zu erreichen, ist man schon dazu übergegangen, verschiedene Geräte der Stromabnehmer durch Fernsteuerung zu betätigen, so daß diese Geräte je nach Erfordernis des Verlaufes der Belastungskurve aus- oder eingeschaltet werden können. Dieser Weg ist insbesondere in der Vergangenheit bei der Einführung der Nachtspeicherheizung zur Auffüllung der sogenannten »Nachtlasttäler« erfolgreich beschritten worden. Durch eine solche Fernsteuerung der Nachtspeicherheizgeräte hat man in der Vergangenheit das Problem der Nachtlasttäler nahezu beseitigt. Ein weiteres Problem stellen noch die zu verschiedenen Tageszeiten, insbesondere mittags und abends auftretenden Lastspitzen dar. Diese Lastspitzen können nur beseitigt werden, wenn zu den betreffenden Tageszeiten die Einschaltung solcher Geräte gesperrt wird, die ohne wesentliche Beeinträchtigung des Nutzens Uiid des Komforts des Gerätebetreibers auch zu einer anderen Tageszeit arbeiten können. Solche Geräte sind beispielsweise Waschmaschinen, Wäschetrockner und Geschirrspülmaschinen.Such control arrangements are known. Electrical energy cannot be stored directly, so each required energy must be generated at the same time in the power plants. Electric power plants, in particular Nuclear power plants work most economically when the power output is as constant as possible. To the however, this is offset by the strongly fluctuating power requirement during the course of a day. To one To achieve a more uniform course of the power requirement, one has already gone over to different Operate devices of the pantograph by remote control, so that these devices as required the course of the load curve can be switched off or on. This path is particular in the Past with the introduction of night storage heating to fill the so-called "night load valleys" has been successfully trodden. With such a remote control of the night storage heaters one has in in the past, the problem of night load valleys has almost been eliminated. They pose another problem at different times of the day, especially at noon and in the evening occurring load peaks. This Load peaks can only be eliminated if they are activated at the relevant times of the day Devices is blocked without any significant impairment of the convenience of the device operator can work at a different time of the day. Such devices are, for example, washing machines, Tumble dryers and dishwashers.

Die Steuerung von Nachtspeicherheizgeräten erfolgt bekanntlich über einen zentral angeordneten Rundsteuerempfänger, durch den ein eigenes Versorgungssystem für die Nachtspeicherheizgeräte ein- und ausgeschaltet wird. Über ein weiteres Versorgungssystem, welches nicht der Fernsteuerung unterliegt, werden die übrigen Geräte gespeist. Die Installation von zwei getrennten Versorgungssystemen ist ohne besonderen Aufwand nur bei Neubauten möglich. Eine nachträgliche Umrüstung erfordert dagegen einen sehr hohen Aufwand. Außerdem können bei der Steuerung mittels eines zentral angeordneten Rundsteuerempfängers immer nur alle Geräte aus- oder eingeschaltet werden. Dies führt dazu, daß die Anzahl der fernsteuerbaren Geräte relativ klein ist.As is well known, night storage heaters are controlled via a centrally arranged ripple control receiver, through which a separate supply system for the night storage heaters is switched on and off will. The other devices powered. The installation of two separate supply systems is without special Expenditure only possible for new buildings. Subsequent retrofitting, on the other hand, requires a very high rate Expenditure. In addition, when controlling by means of a centrally arranged ripple control receiver only all devices are switched off or on at a time. This leads to the number of remotely controllable Device is relatively small.

Der Erfindung liegt die Aufgabe zugrunde, eine Steueranordnung zur Beeinflussung des Leistungsbezugs der elektrischen Geräte eines Stromabnehmers der eingangs genannten Art so auszubilden, daß eineThe invention is based on the object of a control arrangement for influencing the power consumption to train the electrical devices of a pantograph of the type mentioned so that a

ίο wesentlich größere Anzahl von elektrischen Geräten durch Fernsteuerung aus- und eingeschaltet werden kann, ohne daß der Gerätebetreiber wesentliche Einschränkungen hinnehmen muß. Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Mittel gelöst.ίο Much larger number of electrical devices can be switched off and on by remote control without the operator of the device being essential Has to accept restrictions. This object is achieved according to the invention by the in the characterizing part of claim 1 specified means solved.

Dadurch sind vorteilhafterweise zusätzliche Rundsteuerempfänger dezentral in den einzelnen Geräten selbst angeordnet, so daß für ein Elektrizitätsversorgungsunternehmen (EVU) die Möglichkeit besteht, bestimmte Gerätegruppen je nach Erfordernis der Tagesbelastungskurve aus- oder einzuschalten. Durch den zentral beim KWh-Zähler angeordneten Rundsteuerempfänger wird lediglich an dem Zähler eine Tarifumschaltung vorgenommen. Durch entsprechende Tarifgestaltung hat das EVU auch die Möglichkeit, für den Stromabnehmer einen Anreiz zu schaffen, in lastschwachen Zeiten, in denen der Strom zu einem niederen Tarif zur Verfügung steht, verstärkt Strom zu beziehen oder durch einen besonders hohen Tarif zu Zeiten der Lastspitzen den Stromabnehmer von einem verstärkten Verbrauch abzuhalten.As a result, additional ripple control receivers are advantageously decentralized in the individual devices self arranged so that for an electricity company (EVU) there is the possibility of switching certain device groups off or on depending on the requirements of the daily load curve. By the ripple control receiver arranged centrally at the KWh meter is only one on the meter Tariff changeover made. By structuring appropriate tariffs, the RU also has the option of the pantograph to create an incentive in times of low load when the electricity is at a lower tariff is available to purchase more electricity or through a particularly high tariff Periods of peak loads to keep the pantograph from increased consumption.

Vorteile ergeben sich auch, wenn bei Geräten mit einem programmierbaren Steuerwerk der dem Gerät zugeordnete Rundsteuerempfänger derart mit diesem Steuerwerk zusammenarbeitet, daß beispielsweise dem Steuerwerk über den Rundsteuerempfänger eine Information über den voraussichtlichen Verlauf des Strompreises gegeben wird. Das Gerät wird dann über sein Steuerwerk unter Abstimmung seiner auszuführenden Aufgaben mit der Strompreiskurve zu solchen Zeiten eingeschaltet, daß die Stromkosten für den Verbraucher ein Minimum werden. Da der günstige Strombezugspreis jeweils dann gilt, wenn ein Belastungstal vorhanden ist, werden die Geräte jeweils zu dieser Zeit eingeschaltet und tragen somit zum Abbau der Lastspitzen und zum Auffüllen der Belastungstäler bei. Die Informationen über den Verlauf der Strompreiskurve können von dem EVU als Impulssignale an die Rundsieuerempfänger gesendet werden, die diese Informationen an die programmierbaren Steuerwerke weiterleiten. Derartige Steuerwerke können z. B. aus einem kleinen Rechner bestehen.There are also advantages if, in devices with a programmable control unit, the device associated ripple control receiver cooperates with this control unit that, for example, the Control unit via the ripple control receiver information about the probable course of the Electricity price is given. The device is then to be executed via its control unit with coordination of its Tasks with the electricity price curve switched on at such times that the electricity costs for the Consumer will be a minimum. Since the favorable electricity purchase price applies whenever there is a high load is available, the devices are switched on at this time and thus contribute to the degradation the load peaks and to fill in the load troughs. The information about the course of the electricity price curve can be sent by the EVU as pulse signals to the broadcast receivers, which these Forward information to the programmable control units. Such control units can, for. B. off a small computer.

Damit der Gerätebetreiber in Notfällen jederzeit sein Gerät benutzen kann, wird man zweckmäßigerweise eine Möglichkeit zum Aufheben einer durch den Rundsteuerempfänger vorgegebenen Sperre vorsehen. Die den Geräten zugeordneten Rundsteuerempfänger können zu einem großen Teil ohne Leistungsschalteinrichtungen ausgeführt werden, da in vielen Geräten Schaltschütze vorhanden sind, die die Aufgabe des Aus- und Einschaltens übernehmen können.So that the device operator can use his device at any time in emergencies, it is expedient Provide a way to cancel a predetermined by the ripple control receiver lock. Most of the ripple control receivers assigned to the devices can be operated without power switching devices be carried out, as there are contactors in many devices that perform the task of and switch on.

Die dezentrale Zuordnung der Rundsteuerempfänger zu den einzelnen Geräten hat weiterhin den Vorteil, daß der Leistungsverbrauch der Erzeugung besser angepaßt werden kann, da die einzelnen Gerätegruppen jeweils für sich gezielt aus- oder eingeschaltet werden können.The decentralized assignment of the ripple control receiver to the individual devices also has the advantage that the power consumption of the generation can be better adapted, since the individual groups of devices can be switched on or off specifically for themselves.
