Unit for solar and wind energy utilisation

Abstract

The goal of the invention is to maintain a constant supply of electrical energy with use of solar and wind power. According to the invention there is a generator and a first motor mounted on the shaft of the column, where said generator is connected, through a first relay and inverter with a power grid and the generator is also connected, through rectifier with a battery pack. Rotary guides, connected with second motors are covered with a layer with photovoltaic cells.

Description

[0010] The subject matter of the invention is illustrated in the exemplary embodiment in drawings, where FIG. 1 shows the column with one guide and the block diagram of electrical connections, and FIG. 2 shows the cross-section of the unit with four guides.

[0011] The unit for wind and solar energy utilisation consists of two vertical axis wind turbines 1 covered with a roof 2. The wind turbine 1 is assembled with a rotor 3 and casing 4, said casing having guide vanes 4a. Between the wind turbines 1 there are fairings 5. On the shaft 6 of a column there is a first electric motor 7 and generator 8. Around the column there are rotary guides 9, masts 10 of said guides 9 are connected with second electric motors 11. Power outlet of the generator 8 is connected through the first relay 12 and inverter 13 with power grid 14, and is also connected via rectifier 15 with the battery pack 16, outlet of which is connected through a second relay 17 and converter 18 with the power grid 14, and with the second electric motors 11. The guide vanes 4a, roof 2, fairings 5 as well as rotary guides 9 are covered with foil 19 with photovoltaic cells wherein the guide vanes 4a are covered with foil 19 with photovoltaic cells on both sides. Power outlet of photovoltaic cells is connected through third relay 20 with the first electric motor 7, and with battery pack 16, and the outlet of photovoltaic cells is connected through fourth relay 21 and inverter 13 with the power grid 14. Relays 12, 17, 20 and 21, as well as a wind speed and direction sensor 22 and following sensor 23 are connected with the control system 24.

[0012] The first electric motor 7 is designed to start the wind turbines 1, and in case of strong wind there is a possibility to set it in such a way, so that it fulfills the functions of the generator. If the wind blows with proper speed, one guide 9 is set in the position, in which the wind pushes on its largest surface, and the three other guides 9 are set perpendicularly, in one plane, to the angle of the rays of sun. In case of lack of wind with proper speed, and good insolation, all rotary guides 9 are set towards the sun, and are the main source of power to the power grid 14. At the same time, if the generator 8 or photovoltaic cells generate electric current, the control system 24 provides total and constant charge of the battery pack 16.
