DESCRIPTION

GEO (OPTIMIZED ELECTRONIC MANAGEMENT OF ELECTRIC ENERGY)

OBJECT OF THE INVENTION

The present invention refers to a new circuit, apparatus, system, equipment capable of managing electrical energy by combining the different sources available with the existing loads. When these loads are not reactive, the energy stored in direct current is supplied in the same way, that is, without converting it into alternating current, allowing the operation of its loads regardless of the nature of the electrical supply (direct and alternating current) and with unprecedented efficiency and reliability thus avoiding energy losses in the conversion of voltage and type of current and the problems generated by the use of alternating current when converting it (harmonics...) and applicable to any type of machines, tools , systems, equipment..........that require electricity supply.

It must be said that these loads, including the electronic ones with rectifier bridge input impedance, can be supplied both in direct current and in alternating current since the polarity is irrelevant, as long as the effective value is the same or is within the same range. .

FIELD OF THE INVENTION

This invention has its application in the supply of electrical energy to all circuits, devices, systems, equipment... that use electrical energy and that do not have a reactive input impedance.

BACKGROUND OF THE INVENTION

As is known, direct current is the form in which electrical energy is present in nature and was discovered by Volta in the development of the first electric battery. The battery and/or accumulator is the most common form of electrical energy storage and works at direct voltage supplying direct current.

Electrical energy is the product of the voltage times the intensity times the power factor per unit of time, so to transport large quantities with low voltages, very high currents are needed and therefore large sections of conductor.

At present, most of the electronic equipment that requires electrical fluid incorporates electronic circuits, whose operation is in low voltage direct current, for which it is necessary to transform and rectify the electrical fluid received from alternating current to direct current with advantage. (stabilization, filtering.....). Said process can be carried out either by means of a transformer or by means of a switching power supply. Currently, the dominant alternative is this, since it has advantages over transformers, which remain as heavy elements with large losses (eddy current, Joule heat losses...) and use a lot of copper, which makes it more expensive the same.

This leads us to the feasibility of the current invention for the supply of direct current power for all circuits, devices, equipment systems... that do not have a reactive load (including those equipped with a switching power supply that have an input impedance in the form of a bridge rectifier).

DESCRIPTION OF THE INVENTION

The electronic electrical energy management system that the invention proposes constitutes a novelty within its field of application, since the invention consists of supplying the generated and consumed electrical energy in the same way (direct current), as long as they have the same effective voltage (regardless of frequency) within the margins tolerated by the transmitter and receiver.

This system is made up of an electronic control unit and an accumulation unit with interaction between them.

The energy inputs can come from various sources such as solar, wind, generator sets, conventional network, hydraulic... The storage system is made up of a series of cells of different technologies (lead, lithium ..).

The set has an electronic control device that is capable of managing the intervention of any of the electric power generators, at any time, as well as the recharging of the accumulators (if any). In this way, the electronic control device is capable of detecting the state of charge of the accumulators (if any) and acting accordingly. In the event of a low charge level, it will manage the energy input optimally.

For normal service, using the appropriate computer program, charge cycles of frequency and duration depending on the type of accumulator are established.

PREFERRED EMBODIMENTS OF THE INVENTION

The system consists of accumulators of electrical energy connected in series until reaching the range of the supply voltage. A charger / source charges and maintains the accumulators (in float) while there is input voltage. The accumulators supply voltage to the loads when the charger/source does not supply enough energy. In the event of a total supply failure, the loads do not appreciate any variation since the power supply comes entirely from the accumulators. The system monitors the level of charge of the batteries and manages the outputs based on their importance and the remaining autonomy time. In the event that the accumulators reach a critical point of discharge without having restored the supply, an alarm warns of the situation and cuts off the output to protect the batteries.

Likewise, when there is a variable supply source such as that from solar, wind, hydraulic energy, ...... ,.the accumulators store electrical energy and supply the loads. In the case of the electricity network, periodic rates can be used to charge at the most profitable intervals.

A control team is responsible for connecting the different energy sources with the different loads, optimizing energy management, transferring networks, storing, supplying energy without interruption, acquiring it in the most profitable period, stabilizing it, filtering it...
