Description: METHOD OF GENERATING ELECTRICAL ENERGY AND APPARATUS FOR CARRYING OUT THE METHOD Technical Field This invention relates, in general, to a method for generating electricity by making use of centrifugal acceleration of liquid, whereby generated pressure acts on a rotor along its circumference. In particular, it relates to a type of equipment for carrying out this mode, whereby mechanical energy is transferred from a rotor mechanism via hydraulic motors to a power generator. Background Art Generally, electric power is generated by means of water and wind power stations provided with rotors of far greater diameters, while major disadvantages of these are usually their high initial outlays and constraints pertaining to their limited electric power output. The only available alternative mode for generating electricity, based on parallel flow, and corresponding equipment according to the patent No. 278 118 (SK) has been unsuitable for other than wind power stations. A mode based on operation of pumps, according to description of the invention subject to certificate No. 164 452, which relates to pump turbines comprised of a rotary distribution gate box, and the aeration of the impeller chamber before turbine is started, addresses the pump start up in theoretical form only, with known impacts such as excessive vibrations, resulting in extreme vulnerability of equipment to failures during operation. Equipment for generating electricity according to description of the invention subject to certificate No. 250 417 that is comprised, in general, of a floating casing, water turbine, generator, supply and discharge pipe, and uses only water level differential for generating electricity. A linear hydraulic motor according to description subject to certificate No.196 906 (CZ) and hydraulic motor according to industrial design No. 7606 (CZ), do only address connection to a driving mechanism with rotating tools. A turbine of impulse type as per description subject to certificate No. 198 349 (SK) and water turbine according to industrial design No. 8877 (CZ), may be used for low water pressure differential only, and offer but low efficiency. Another solution of equivalent technical features and close to design concept as in subject to this invention is a centrifugal type water power plant as per pending patent application PV No. 886-98 (CZ), which uses centrifugal forces generated in arms of a centrifugal unit immersed in water, and impellers placed on arm outlets, connected via shafts to a water turbine, whereby rotation of this centrifugal unit results in centrifugal forces, which push water onto impellers, while these are caused to rotate and transfer energy thus generated to a water turbine used for generating electricity, and water leaves the turbine via outlets in rotating arms to flow back to water tank. Centrifugal forces create negative pressure in the centrifugal unit, which results in water being transferred back via inlet pipe into this unit. The tank and centrifugal unit create vessels with matched levels, the energy loss due to necessity of water transfer back into centrifugal unit being thus kept at a minimum. A major disadvantage of a rotor immerged in water is the increased friction, which results in greater power requirements. Another disadvantage of this solution is the great amount of energy needed for pumping large amounts of water. Disclosure of Invention The above disadvantages may be reduced, to some extent, by using a mode for generating electricity that comprises a controllable electric motor for driving a disc shaped rotor generating centrifugal forces which, in turn, accelerate the liquid and result in building pressure in a ratio quadratic to circumferential velocity measured at the outer rim of a disc shaped rotor, the main principle being in that the liquid is supplied via feeding valve into a storage tank while the disc rotor is continuously filled with liquid to constant level, the liquid being transferred between two vessels with matched levels, one of them being the stator and the other one rotor of a disc shape, and centrifugal forces and energy potential due to centrifugal acceleration being used to drive a hydraulic motor which, in turn, rotates the coupling shaft, transferring thus energy to an electric generator, the energy take-off being provided via collector rings and carbon collector units. An advantage of this mode of generating electricity is that the rotor rotates in free air, the friction and subsequent energy needs thus being considerably reduced. Another advantage pertaining to this mode is that the equipment used for carrying out this mode for generating electricity consists of a stator and a discshaped rotor and these are coupled to a controllable electric motor driving unit, whereby these units are creating two vessels with matched water levels, while the stator consists of a support attached on one end to a circular trough, the other end being connected to a liquid storage tank with a feeding valve, this tank being provided, on its side-wall, with at least one hollow coupling arm connected to a circular trough with a cutting accommodating a freely movable and attachment joint free discharge pipe on a hydraulic motor, this hydraulic motor being coupled via driving shaft to the electric generator, the third equipment part comprising the inlet hole and rotor skeleton piping connected via corresponding chamber and a hollow shaft to the liquid tank. The vessels with matched levels are comprised of a circular trough, two coupling hollow arms, liquid storage tank, hollow shaft, chamber and rotor skeleton piping. An advantage of the present invention is that a disc-shaped rotor consists of a rotor skeleton piping, rotor casing and rotor-driving shaft. Further advantage of this solution with respect to loading by centrifugal forces is that the generator is mounted in axis of the disc rotor. Further advantage of this solution is that the bottom part of a hollow shaft faces the middle part of the liquid storage tank and its upper part with a watertight mount is firmly attached to the disc-shaped rotor. Further advantage is provided by a fully hermetical attachment of the negative pressure top cover with valve. Further advantage of this solution is that at least one hydraulic motor is mounted on a circular pipe and connected, through its inlet to at least one outlet pertaining to rotor skeleton piping.
