Description
Vorrichtung zum pumpen von Wasser mit Energierückgewinnung.Device for pumping water with energy recovery.
Vorrichtungen üblicher Bauart weisen eine Turbine auf, welche mit dem überschüssigen Strom aus dem Ver= bundnetz in Schwachlastzeiten das Wasser aus einem Vorratsbecken in ein höhergelegenes Oberbecken pumpen. In Spitzenlastzeiten läuft das Wasser aus dem Oberbecken zurück und erzeugt durch eine Turbine mit einem nachgeschaltenen Motor- Generator den notwendigen Spitzenstrom für das Verbundnetz.Devices of a typical design have a turbine which, during off-peak periods, uses the excess electricity from the interconnected network to pump water from a storage basin into a higher upper basin. During peak periods, the water flows back from the upper basin and generates the necessary peak electricity for the interconnected network using a turbine with a downstream motor-generator.
Im Jahr 2002 bis 2003 erfolgt die Inbetriebsetzung der vier Pumpspeichersätzedes PSW Goldisthai in Thüringen. im Auftrag der VEAG. Dieses Pumpspeicherkraftwerk ist eines der modernsten Anlagen dieser Art.In 2002 and 2003, the four pumped storage power plants of the Goldisthai pumped storage power plant in Thuringia were commissioned on behalf of VEAG. This pumped storage power plant is one of the most modern plants of its kind.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Pumpspeicheranlage zu schaffen, welche einen Teil der notwendigen Energie zum hochpumpen des Wassers, welche in Form von Druckluft in einem Druckbehälter gespeichert bleibt, über eine Luftturbine zurückgewinnt.The invention specified in claim 1 is based on the problem of creating a pumped storage plant which recovers part of the energy required to pump up the water, which remains stored in the form of compressed air in a pressure vessel, via an air turbine.
Dieses Problem wird mit den in Schutzanspruch 1 aufgeführten Merkmalen, ein E- Kompressor, ein Druck= kessel und eine Luftturbine mit Generator gelöst.This problem is solved with the features listed in claim 1, an electric compressor, a pressure vessel and an air turbine with generator.
Mit der Erfindung wird erreicht, das der Druckkessel mit E- Energie aus dem Verbundnetz über den Kompressor mit Druckluft vollgepumpt wird und das Wasser aus dem Druckkessel über eine Rohrleitung ins Oberbecken pumpt. Der Luftdruck im Kessel bleibt bei geschlossenen Schiebern erhalten. Im Oberbecken erfolgt eine Ener= giespeichening durch die Höhenlage des Wassers und im Druckkessel erfolgt eine zeite Energiespeicherung durch Druckluft. Wenn der Schieber zur Luftturbine hin geöffnet wird, erzeugt ein, der Luftturbine nachgeschaltener Generator zusätzliche E- Energie.The invention ensures that the pressure vessel is filled with electrical energy from the network via the compressor and is pumped with compressed air, and the water from the pressure vessel is pumped into the upper basin via a pipeline. The air pressure in the vessel is maintained when the slide valves are closed. Energy is stored in the upper basin due to the height of the water, and further energy is stored in the pressure vessel using compressed air. When the slide valve is opened towards the air turbine, a generator connected downstream of the air turbine generates additional electrical energy.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben.An advantageous embodiment of the invention is specified in claim 2.
Die Weiterbildung nach Schutzanspruch 2 für die maximale Ausnützung der Anlage zur Spitzenstromerzeugung wird durch eine Turbine mit Generator ermöglicht, wenn das Wasser aus dem Oberbecken über die Rohrleitung und die Turbine in den Behälter zurückläuft. Dabei wird mit dem der Turbine nachgeschaltenen Generator E- Energie für das Verbundnetz erzeugt.The further development according to claim 2 for the maximum utilization of the system for peak power generation is made possible by a turbine with generator when the water from the upper reservoir flows back into the tank via the pipeline and the turbine. The generator connected downstream of the turbine generates electrical energy for the interconnected grid.
Ein Ausfuhrungsbeispiel der Erfindung wird anhand der Figur 1 erläutert. Es zeigt:An embodiment of the invention is explained using Figure 1. It shows:
Fig. 1 die potentielle Lagerung der Energie im Oberbecken.Fig. 1 the potential storage of energy in the upper reservoir.
In der Figur 1 ist der Kompressor 1 mit dem E- Motor 2 dargestellt, welcher in der Schwachstromzeit aus dem Verbundnetz 3 den Strom für den Antrieb bezieht. Der Kompressorausgang ist über die Rohrleitung 4 direkt mit dem Kessel 5 verbunden. Die Druckluft aus dem Kessel 5 entweicht, wenn der Schieber 6 geöffnet wird über die Rohrleitung 7 und dreht die Turbine 8. Der nachgeschaltene Generator 9 erzeugt Strom bis der Kessel 5 fast leer ist. Der Drucksensor 13 im Kessel 5 und das Staurohr 14 in der Rohrleitung 7 sind die Sensoren zur Steuerung von Schieber 6. Dieser wird langsam geöffnet, damit die Druckluft aus dem Kessel 5 gleichmäßig entweicht und die Turbine 8 ihre Drehzahl annähernt gleichbehält. Der nachgeschaltene Schalldämpfer 10 re= duziert das Geräusch der Druckluft beim Austritt ins Freie.Figure 1 shows the compressor 1 with the electric motor 2, which draws the power for the drive from the grid 3 during low-voltage times. The compressor outlet is connected directly to the boiler 5 via the pipe 4. When the slide valve 6 is opened, the compressed air from the boiler 5 escapes via the pipe 7 and turns the turbine 8. The downstream generator 9 generates power until the boiler 5 is almost empty. The pressure sensor 13 in the boiler 5 and the pitot tube 14 in the pipe 7 are the sensors for controlling the slide valve 6. This is opened slowly so that the compressed air escapes evenly from the boiler 5 and the turbine 8 maintains approximately the same speed. The downstream silencer 10 reduces the noise of the compressed air as it escapes to the outside.
Über die Stromspeicher 11, die Batterien und Einspeisungskasten 12 wird die E- Energie bei Spitzenstromzeit in die Vcrbundleitung 3 zurückgeführt. Die Wasserrohrleitung 15 verbindet den Kessel 5 über den Schieber 16 mit dem Oberbecken 20. Dieses Oberbecken ist mit Wasser 19 aufgefüllt dargestellt. In diesem Zustand sind die Schieber 16 und 18 geschlossen. Der Filter 21 ist der Rohrleitung 17 vorgeschaltet, gemeinsam mit der Abdeckung 28 wird damit der Wasserverschmutzung vorgebeugt.During peak periods, the electrical energy is fed back into the interconnection line 3 via the power storage units 11, the batteries and the feed box 12. The water pipe 15 connects the boiler 5 to the upper reservoir 20 via the slide valve 16. This upper reservoir is shown filled with water 19. In this state, the slide valves 16 and 18 are closed. The filter 21 is connected upstream of the pipe 17 and, together with the cover 28, prevents water pollution.
Beim Wasserrücklauf vom Oberbecken 20. über die Rohrleitung 17. bei geöffneten Schieber 18 dreht die TurbineWhen the water returns from the upper reservoir 20 via the pipe 17 with the valve 18 open, the turbine rotates
22. Der, der Turbine 22 nachgeschaltene Generator 23 giebt über den Einspeisungskasten 24 E- Energie an das Verbundnetz bei Spitzenstromzeiten ab, wenn das Oberbecken 20 entleert wird .22. The generator 23 connected downstream of the turbine 22 supplies electrical energy to the interconnected grid via the feed-in box 24 during peak power times when the upper reservoir 20 is emptied.
Die Füllstandssensoren 25 , 27 und der Druckschalter 13 fühlen die Füll-und Druckzustände in den Behältern ab und die Elektronische Schaltung 26 steuert, entsprechent der Messdaten sowie des Strombedarfs die Schieber 6. 16 und 18 und den Kompressor 1.The level sensors 25, 27 and the pressure switch 13 sense the filling and pressure conditions in the containers and the electronic circuit 26 controls the slides 6, 16 and 18 and the compressor 1 according to the measurement data and the power requirement.
