The land-based weather and inspection shaft on the coast serves as ventilation and air shaft. Ref country code : CH. A pumped storage plant can use the hydrostatic water pressure in the depth of a natural deep-water channel. However, in contrast to this has on storage tunnel or tunnel which are guided below the sea floor and partly to less firm ground land or an island and can be bewettert over the fixed land. A machine underground chamber 7 includes a connection to the former end section.

The inlet and outlet structure is preferably provided with means for retaining contaminations, such as a sludge trap, a flushing device and spatial rake for the off or flowing water. In other words, this means that the ultrasonic transducer 7 in the first region between t min and t target at the same time is excited by a smaller frequency spectrum than in the area between t target and t max.

When draining the excess pressure, the compressed air can then drive one or more turbines.
What is essential is that the frequency differences may have the above-mentioned amount of combinations during the respective frequency sweeps. The routing of the energy produced, for example, in newly built or upgraded offshore wind turbines on additional routes to the existing or newly constructed pumped storage plants known type caused to a significant line losses, lengthy to another approval process and substantial construction costs.

Als Wasserspeicher dient mindestens ein Hohlraum, der zB die Form eines unverzweigten oder verzweigten Tunnels oder Stollens besitzt.
A separate pressure tunnel connects the deep sea with the machine cavern. The frequency deviation of the sweep modulation is defined as the difference between the maximum frequency and the minimum frequency.

|In this way, the efficiency of excitation of the converter is again increased.
CNA en. The released demolition material of the shaft and the cavity can be used eg for Kolksicherung of wind turbines in the surrounding offshore wind farms. Such a pumped storage power station has to fight the one hand to a reduction of the created by the pumping of water from the cavern by the potential energy back into flowing through the cavern walls water.
It is essential that the transducer region is exceeded or during the sweep of the excitation frequency modulation symmetrically up and down below. According to an alternative embodiment, in the course of at least one frequency sweep, preferably all frequency sweeps, varying the excitation frequency of the drive signal so that the drive signal is the minimum frequency at a first time t 1the target frequency at a second time t 2 and the maximum frequency at a third time t 3wherein the second time between the first and the third time, and wherein a first time difference between the first time and the second time and a second time difference between the second time and the third time magnitude are the same.
Waters-pumped storage power plant according to claim 6, wherein the additional shaft is designed as inspection chamber with further functions, preferably chosen from supply, maintenance and venting functions.

Then, after the air from country flows forth.
In specific embodiments a plurality of separate or interconnected nacelles may be in the machine hall or in a plurality of different, preferably located machines caverns each other in the vicinity may be provided, in which, for example, pump s and turbine s housed with connection to a plurality of first end portions of the hollow body. The PSW stores energy by the displacement of water from a preferably at least largely water-tight, closable generally hollow body with at least one arranged in a bottom of a water body first end portion and a second end portion which is located below a land surface.
With low energy requirements which serves as a water reservoir cavity via the pump function of the optionally present pump-turbines or by means of the pumps is at least partially evacuated. In combination with the inexhaustible supply of the storage medium of water, the electrical energy can, for example in particular of a wind farm are stored mainly in the offshore sector in large quantities directly at the site of power generation with the inventive device.

During flooding, it is favorable to allow through the open areas of a synchronization of the turbine. Such a pumped storage power station has to fight the one hand to a reduction of the created by the pumping of water from the cavern by the potential energy back into flowing through the cavern walls water.
Semiconductor wafer immersion systems and treatments using modulated acoustic energy. Am Einlaufbereich des Druckstollens wird ein Verschlussorgan mit einer Rechenanlage und einem Einlaufbauwerk installiert. There is also the possibility of using pump turbines, which can serve both functions. This form of variation of the sweep modulation is then particularly advantageous if the desired target frequency is not known exactly, but in the course of the proceedings and has to be determined over the frequency sweeps.
