Abstract

The energy module (hereinafter EM) of increased reliability using wind and solar energy belongs to the field of alternative current sources, namely to solar panels and wind generators, and is intended for domestic use as a source of electricity. EM consists of a vertical rack on which an orthogonal (carousel) type rotor is installed. A solar panel is mounted above the rotor. EM is autonomous, it includes a battery and a controller, which allows for optimal battery charging current from two sources. EM differs from the well-known hybrid plants in increased reliability in winter. To this end, the following measures have been taken: the rotor is mounted on bearings that do not have contacting surfaces (for example, magnetic). A simple orthogonal (rotary) three-blade rotor having a small area of vertical surfaces is used. The surfaces are polished and coated with a hydrophobic film. The solar panel is covered with a transparent, polished outside, conical shape with an angle at the apex sufficient to ensure its self-cleaning. The location of the solar panel above the rotor further protects it from precipitation. The EM design allows you to connect it into modular groups to obtain the desired power (additional controller function, connector). Application: as the main or backup power source in household plots. In the urban economy - lighting, traffic signs, parking meters, charging points.

Description

Energy module using wind and solar energy.

The proposed energy module, hereinafter (EM), relates to the field of alternative current sources, namely to solar panels and wind generators, and is intended for domestic use as a source of electricity.

Class HO2J 7 \ 35, FO3D 3 \ 00.

Known multifunctional hybrid alternative power plant, patent RF2528627 publ. 09/20/2014, containing a support, a wind generator, photovoltaic modules, a rechargeable battery, an LED lamp and a reregulator. The disadvantage of such a station is its immobility with respect to the direction of the wind, and the need for maintenance, especially in the autumn-winter period.

Known power plant for the use of wind and solar energy according to the patent of the Russian Federation 2347942, published on 02.27.2009, containing a vertical shaft located on the foundation with an electric generator consisting of a stator and rotor and rocker arms on which the blades are mounted. Moreover, the blades consist of several parallel tiers separated by gaps.

The upper part of the fixed axis is equipped with a platform on which the solar battery is installed. The installation contains a battery and an inverter. The disadvantage of the installation is its metal consumption, noise during operation. In the autumn-winter time, the operation of the installation is hardly possible. Many blades, which have a number of parallel plates, including flexible ones, will inevitably be clogged with snow and ice in winter. For the same reason, the operation of the solar battery is disrupted. Maintenance is required, and when the installation is located at a height, such work is difficult.

Known street lamp powered by wind and solar energy according to the patent of the Russian Federation 2283985, publ. 09/20/2006, containing a vertical post, cantilever support arm, and a single module placed on it. The module consists of photovoltaic panels of an oscillating wind generator, a battery, a control unit and lamps. Disadvantages - low efficiency of the wind generator, for the operation of which a frontal gusty wind of sufficient strength is required, and also low efficiency of solar panels, due to their vertical position.

As a prototype, as the closest in design to the proposed EM, adopted the aforementioned power plant according to the patent of the Russian Federation 2347942

A common disadvantage of known power plants is their lack of reliability in the winter.

The aim of the EM design is to attempt to eliminate the above disadvantages of known energy devices. EM is a complete stand-alone structure consisting of a rotor of a wind generator mounted on an axis, a solar panel mounted above it, a generator connected to the rotor of the wind generator, and a battery. The EM includes a controller that provides optimal battery charge current from two current sources, and an output connector for connecting the load, and controlling the optimal orientation of the solar panel during installation.

1. How to increase the reliability of EM in the winter. For this, it is necessary, first of all, to increase the reliability of the main components of the structure, and this is a wind generator and a solar panel.

The solar panel has a sufficiently high reliability provided by the design, and to increase the reliability of its operation in winter time means to protect it from snow and ice.

The cone-shaped solar panel is covered by a transparent, well-polished outside cone-shaped shell, in which the angle at the apex is determined empirically for better self-cleaning.

Wind generator. Its rotor rotates on bearings, which are the most unreliable part of the design. To increase the reliability of a wind generator means to increase, first of all, the reliability of the bearings of its rotor. Bearings should not require maintenance, maintain operability under any climatic and operating conditions.

The rotor of the wind generator is mounted on magnetic bearings.

As a wind generator, a simple scheme of vertical orthogonal (carousel) rotor, with a minimum surface area and not having complex profiles, is adopted. The number of blades is three. The vertical rotor blades do not have flat horizontal surfaces. Connecting them to the axis of the spokes of circular cross section are installed at an angle to the axis. All surfaces of the wind generator are well blown, polished and coated with a hydrophobic polymer film having very low adhesion to ice. (Panyushkin A. V. experimental determination of ice adhesion to structural materials, proceedings of ALNII 1972 t 298 p. 71-77) The battery and controller located in a special compartment are sealed and have a winter design, the stator windings are sealed. This design of the wind generator will increase its performance in winter.

In order for the EM design to be complete in terms of design, it is desirable that the diameter of the rotor and the protective shell of the solar panel be commensurate. In this case, the casing acquires the additional function of protecting the rotor from precipitation.

The proposed EM can work independently. But if you install several such EMs in those parts of the site that are well lit at certain hours of the day, and take into account the strength of the wind, then when these EMs are connected, the system will "pump" excess energy into neighboring EMs and the entire system; will be balanced and have increased reliability and power

The composition of the EM in Fig 1 .: 1 - rack with a vertical axis; 2 - rotor; 3 - solar panel; 4 - transparent shell; 5 - fixed area; 6 - passive magnetic bearing; 7 - compartment for: 8 - generator rotor, 9 - generator stator, 10 - battery, 11 - controller, 12 - output connector. The EM block diagram of FIG. 2: 3 - solar panel; 9 - generator stator, 10 - battery, 11 - controller, 12 - connector. EM can be used both primary and backup current source in personal plots. Vertical wind generators can work with a small, surface wind, so the height of their installation can be limited by the height of buildings, trees, and be inconspicuous. In addition, such relatively low-noise EMs can be used in urban areas - lighting, traffic signs, parking meters, charging points, and more.
