Description
Grundfunktion der Steuereinheit ist die zuverlässige Energieversorgung von häuslichen 230 V~ Verbrauchern durch alternative Energiequellen, wie zum Beispiel Solarmodule oder Windräder.The basic function of the control unit is the reliable power supply of domestic 230 V ~ consumers through alternative energy sources, such as solar modules or wind turbines.
Es wird dem Anwender die Möglichkeit gegeben, schrittweise eine alternative Energieversorgung im Wohnhaus aufzubauen.It will give the user the opportunity given, gradually an alternative energy supply in the residential building build.
Es wird eine bestimmte Zahl von zum Beispiel Solarpanels benutzt, um Akkumulatoren über einen Laderegler LR zu laden. Die Anzahl von Solarpanels ist variierbar, es genügt schon ein Stück.It For example, a certain number of solar panels are used to Accumulators over one Charge controller LR to charge. The number of solar panels is variable, it is sufficient already a piece.
In diesem Fall stellen die Solarpanels die inhärente Energiequelle (IE) dar. Es können auch andere regenerative und konventionelle Energiequellen eingesetzt werden (Regenerative zum Beispiel Windrad, Konventionelle zum Beispiel Notstromaggregat).In In this case, the solar panels are the inherent energy source (IE). It can also other regenerative and conventional energy sources used become (regenerative for example windmill, conventional for example Emergency generator).
Im Normalzustand werden die netzbetriebenen Verbraucher (NV) über die Akkumulatoren und den Wechselrichter mit Strom versorgt. Nur im Falle entleerter Akkumulatoren wird auf den 230 V Netzanschluss umgeschaltet.in the Normal condition, the grid-powered consumers (NV) on the Accumulators and the inverter supplied with electricity. Only in Trap of empty accumulators will be on the 230 V mains connection switched.
Die Akkumulatoren werden dann ausschließlich durch die inhärente Energiequelle IE nachgeladen. Beim Erreichen eines bestimmten Ladezustandes der Akkumulatoren, werden die Verbraucher NV dann wieder durch den Akkumulator beziehungsweise durch die Inhärente Energie quelle IE versorgt.The Accumulators are then exclusively by the inherent energy source IE reloaded. When reaching a certain state of charge of the Accumulators, the consumer NV then again through the accumulator or by the inherent Energy source IE supplied.
Der wesentliche Unterschied zu bestehenden Technologien und Verfahren ist, dass hier die Versorgung durch die alternative Energiequelle (Akkumulatoren und IE) Vorrang hat. Die Steuereinheit kehrt also das Funktionsprinzip üblicher ,Unterbrechungsfreier Stromversorgungen USV' um.Of the significant difference to existing technologies and procedures is that here the supply by the alternative energy source (Accumulators and IE) takes precedence. The control unit returns the operating principle more common , Uninterruptible Power Supplies UPS 'order.
Durch dieses Verfahren kann der Anwender seine laufenden Strom/Energiekosten erheblich und beliebig senken.By This procedure allows the user to track their ongoing electricity / energy costs significantly and arbitrarily lower.
Zentrales Element ist die Ecoset Steuereinheit (ES). Es gibt zwei Möglichkeiten, die entsprechende Funktion aufzubauen: 1) Die ES-Funktion wird in den Wechselrichter integriert und durch Programmänderung/Softwareanpassung implementiert. 2) Es wird eine externe Steuereinheit aufgebaut, die durch externe elektronische oder elektromechanische Schalter die notwendige Funktion realisiert.central Element is the Ecoset Control Unit (ES). There are two possibilities, To build the appropriate function: 1) The ES function is set in the inverter integrated and implemented by program modification / software adaptation. 2) An external control unit is set up, which is controlled by external electronic or electromechanical switch the necessary function realized.
Funktionsweise von 1):How it works 1):
Die Funktion der Steuereinheit wird im Wechselrichter implementiert.The Function of the control unit is implemented in the inverter.
Die Softwareanpassung wird so realisiert, dass der Wechselrichter über seinen bestehenden Anschluss an den Akkumulator die Spannung prüft. Solange die Akkumulatorspannung einen bestimmten Mindestwert hält, speist der Wechselrichter die Verbraucher NV aus dem Akkumulator.The Software adaptation is realized so that the inverter via its existing connection to the accumulator checks the voltage. So long the accumulator voltage keeps a certain minimum value, feeds the inverter loads NV from the accumulator.
Sinkt die Akkumulatorspannung unter einen bestimmten Mindestwert, wird der 230V~ Netzanschluss auf die Verbraucher NV durchgeschaltet. Dies geschieht innerhalb maximal 20 ms, so dass die Verbraucher NV unterbrechungsfrei mit Strom versorgt werden.If the battery voltage falls below a certain minimum value, the 230V ~ mains connection is switched through to the consumers NV. This happens within a maximum of 20 ms, so that the consumers NV are supplied with power without interruption.
Der Wechselrichter überwacht weiterhin die Akkumulatorspannung, bis diese einen bestimmten Schwellwert überschreitet. Der Akkumulator wird hiervon unabhängig durch den Laderegler und IE geladen. Die Messung der Akkumulatorspannung erfolgt zum Beispiel durch Analog-Digital-Wandler oder Vergleichsspannung mit Widerstandskaskade und Komparator.Of the Inverter monitored continue to charge the battery until it exceeds a certain threshold. The accumulator is independent of this by the charge controller and IE loaded. The measurement of the battery voltage takes place, for example through analog-to-digital converter or reference voltage with resistor cascade and comparator.
Wenn die Akkumulatorspannung einen bestimmten Schwellwert überschreitet, schaltet die Steuereinheit wieder auf akkumulatorbasierte Versorgung der Verbraucher NV um. Dies geschieht wiederum innerhalb maximal 20 ms und stellt wiederum eine unterbrechungsfrei Umschaltung dar. Der Schwellwert kann dynamisch angepasst werden, abhängig vom momentanen Ladestrom des Ladereglers.If the accumulator voltage exceeds a certain threshold, the control unit switches back to accumulator-based supply the consumer NV um. This happens again within a maximum 20 ms and again represents an uninterrupted switching. The threshold can be adjusted dynamically, depending on the current charging current of the charge controller.
Priorität der Stromversorgung hat also die akkumulatorgespeiste Seite.Priority of the power supply So has the accumulator-powered page.
Funktionsweise von 2) (die Steuereinheit wird als eigenständiges Gerät aufgebaut):Operation of 2) (the control unit is considered independent Device constructed):
Hier misst die Ecoset Steuereinheit ES die Akkumulatorspannung. Liegt die Akkumulatorspannung über einem gewissen Schwellwert, trennt ES die Verbindung zwischen Wechselrichter und 230 V~ Netzanschluss. Dies geschieht durch ein Schütz (Relais) oder durch Leistungselektronik wie zum Beispiel DIAC oder TRIAC. Durch diese Trennung kann der Wechselrichter den 230 V~ Netzanschluss nicht an NV durchschalten. Üblicherweise, Stand der heutigen Technologie, schaltet der Wechselrichter, auch ,Unterbrechungsfreie Stromversorgung USV' mit Priorität immer den 230 V~ Netzanschluss an NV durch und nur im Falle eines Netzausfalles werden NV durch den Akkumulator versorgt.Here the Ecoset control unit ES measures the accumulator voltage. If the accumulator voltage is above a certain threshold, ES disconnects the connection between the inverter and the 230 V ~ mains connection. This is done by a contactor (relay) or by power electronics such as DIAC or TRIAC. This disconnection prevents the inverter from connecting the 230 V ~ mains connection to NV. Usually, according to today's technology, the inverter, also 'Uninterruptible power supply UPS' with priority always switches on the 230 V ~ mains connection to NV and only in case of power failure NV are supplied by the accumulator.
Sinkt die Akkumulatorspannung unter einen gewissen Schwellwert, schaltet die Steuereinheit den 230 V~ Netzanschluss auf den Wechselrichter durch (aktivieren z. B. eines Schützes, siehe oben). Der Wechselrichter benutzt jetzt die Speisung durch NA für die Versorgung der NV. Der Akkumulator darf nicht durch den Wechselrichter nachgeladen werden. Zu diesem Zweck wird der akkumulatorseitige Stromkreis des Wechselrichters durch ein Schütz (Relais) oder durch Leistungselektronik zum Beispiel MOSFETs getrennt. Die Nachladung der Akkumulatoren erfolgt nun ausschließlich über den Laderegler bzw. durch IE, wie gewünscht. Der Schwellwert kann durch den Ladestrom des Ladereglers dynamisch beeinflusst werden, zu diesem Zweck wird der Ladestrom gemessen.If the accumulator voltage drops below a certain threshold, the control unit switches the 230 V ~ mains connection to the inverter (eg activates a contactor, see above). The inverter now uses the supply by NA to supply the NV. The accumulator is allowed can not be recharged by the inverter. For this purpose, the accumulator-side circuit of the inverter is separated by a contactor (relay) or by power electronics, for example MOSFETs. The recharging of the batteries now takes place exclusively via the charge controller or by IE, as desired. The threshold value can be influenced dynamically by the charge current of the charge controller, for this purpose the charge current is measured.
Die Steuereinheit enthält eine Programmsteuerung beziehungsweise ein Folgeschaltnetzwerk, das zum Beispiel durch Mikrocontroller oder PAL/GAL implementiert wird. Zur Spannungsmessung verwendet die Steuereinheit einen Analog-Digital-Wandler oder eine Vergleichsspannung mit Komparator/Widerstandskette.The Control unit contains a program control or a follow-up network, for example, implemented by microcontroller or PAL / GAL becomes. For voltage measurement, the control unit uses an analog-to-digital converter or a comparison voltage with comparator / resistor chain.
Der Laderegler nutzt zur Speisung des Akkumulators einen unabhängigen Stromkreis.Of the Charge controller uses an independent circuit to power the battery.
Inhärente Energiesysteme (IE) können alle Arten von regenerativen Energiequellen sein, also zum Beispiel Solarmodule, Windräder, etc.Inherent energy systems (IE) can all kinds of renewable energy sources, for example Solar modules, wind turbines, Etc.
Alle Parameter sind einstellbar.All Parameters are adjustable.
