Description

 METHOD OF STATIC GENERATION OF ELECTRIC ENERGY

Scope of invention

The invention relates to electrical engineering, and in particular to methods of producing alternating current and can be used in the field of production of electrical energy.

Prior art

The closest in technical essence to the claimed invention is a method of generating alternating current at a power plant, involving the execution of a specific sequence of mechanical actions and physical processes leading to the final result - the generation of electrical energy (Ivanov-Smolensky AB Electromagnetic forces and energy conversion in electric machines. - M .: VS, 1989, 312 c). The known method begins with the application of external energy in the form of steam, for example, to a mechanical drive - a steam turbine in order to inform it of the rotational motion, which is transmitted through a coupling to the rotor with electromagnets of an induction electric generator. Rotating permanent electromagnets when passing opposite the ends of the stator cores of the induction electric generator send them a magnetic pulse of constant magnetic flux, which does not lead to the appearance of current in the coils mounted on the stator cores. The continued rotation of the rotor leads the electromagnet poles out from under the stator cores, while the constant magnetic flux in the cores decays, varying in size, which leads to the generation of electrical energy in the stator coils of the induction generator, which is fed into the electrical circuit of the load.

The main disadvantage of this method is a mechanical drive that uses the energy of falling or fast flowing water, wind, converted energy of organic fuels in the form of steam for steam turbines or hot gases in internal combustion engines, which has complex and unreliable designs - both factors lead to a high cost of generated electrical energy , environmental degradation. Brief summary of the invention

The basis of the invention is the task of improving the method of static generation of electrical energy, in which the stator of the induction generator is flat, partially closing the coils with the cores of the induction generator to the stator, connecting to the terminals of the electrical circuits of the load and the electronic control device (EC), creating through them in the cores and a flat stator pulses of varying magnitude of magnetic fluxes, connecting the EMP to the primary source of constant ka - to the battery through the switch-on switch of the ECA and the supply of DC pulses to the coils in each half-cycle of an AC sinusoid with the break of its electric circuit after their supply, the appearance in the cores and the stator of pulses of varying magnitude magnetic fluxes that generate AC in the electric generator coils electrical circuit of the load and on the diode bridge with a filter - capacitor provides a simplified design by replacing the mechanical drive with an ECF with a primary source of constant m ka (battery), this ensures that power reduction of weight is more than three times, reducing the cost of electricity generated, improving the environment.

The task is solved by the fact that in the method of static generation of electric energy, including a power station with an AC induction generator, having a stator, coils with cores, a primary DC source, an electrical circuit in which alternating current is generated, according to the invention:

- fed through the electronic keys pulses of direct current from the ECM to the coils in each half-cycle of an sinusoidal alternating current with the break of its electric circuit after their supply, which leads to the appearance in the cores and the flat stator of pulses of varying magnetic fluxes;

- impulses of varying magnitude of magnetic fluxes in the cores generate an alternating electric current in the coils; - alternating electric current enters the electrical load circuit and the rectifier diode bridge with a smoothing filter - capacitor;

- after the diode bridge, the direct current flows to the ECM for its constant power supply; - The battery is switched to standby mode or automatic charging.
