Abstract
The invention discloses an agricultural photovoltaic power generation structure. A photovoltaic agricultural power generation unit comprises a photovoltaic power generation device and agricultural facilities. The photovoltaic power generation device comprises a photovoltaic support, photovoltaic assemblies, photovoltaic grid-connected equipment, and photovoltaic control equipment. The photovoltaic support is disposed above crops, and the photovoltaic control equipment controls a part of photovoltaic assemblies to supply power to the agricultural facilities. The remaining photovoltaic assemblies are connected to the photovoltaic grid-connected equipment, so as to connect a commercial power network. The photovoltaic grid-connected equipment is connected to a solar grid-connected inverter through a lightning arrester and a DC circuit breaker in a DC combiner box, and the solar grid-connected inverter employs MPPT (maximum power point tracking), and converts a direct current into an alternating current. The alternating current from the solar grid-connected inverter is connected to an AC circuit breaker and a bidirectional intelligent meter. The structure is simple, and improves the agricultural modernization.
Description
Technical field
The present invention relates to agricultural development field, more particularly to agricultural photovoltaic power generation structure.
Background technology
Solar energy power generating is cleaning, emerging generation mode safe, with the largest potentiality; because the use of solar energy has the significance saved conventional energy resource, conservation of nature environment, promote economic development and uplift the people's living standard, so develop solar energy has obtained the consistent accreditation in countries in the world.China is a large agricultural country, still very big to the demand of agriculture plantation, also more and more extensive to the demand of agricultural facility.How on the basis of agricultural planting is not affected, develop photovoltaic system.And the power supply sent by photovoltaic generating system becomes an emerging problem developing green agriculture again.
The content of the invention
The purpose of the present invention is that offer agricultural photovoltaic power generation structure, can be fully solved the problems referred to above.
To achieve these goals, the technical solution used in the present invention is such：Agricultural photovoltaic power generation structure, the photovoltaic agricultural generator unit includes photovoltaic power generation apparatus and agricultural facility；The photovoltaic power generation apparatus include photovoltaic bracket, photovoltaic module, grid-connected equipment and photovoltaic control device, the photovoltaic bracket is arranged at crops top, photovoltaic module is powered for the agricultural facility described in the photovoltaic control device control section, and remaining described photovoltaic module is connected to the grid-connected equipment to access electricity network；The grid-connected equipment is incorporated to solar grid-connected inverter by the arrester and dc circuit breaker in direct current conflux case, solar grid-connected inverter adopts MPPT MPPT maximum power point trackings, direct current is converted into alternating current, from the alternating current that solar grid-connected inverter inversion goes out, incoming transport breaker and Bidirectional intelligent ammeter.
Preferably, the shaded area of the solar panel of the photovoltaic module less than the photovoltaic agricultural generator unit shared by total cultivated area 25%, or for the photovoltaic agricultural generator unit shared by total cultivated area 60-70%.
Compared with prior art, it is an advantage of the current invention that：The present invention is improved by structure, the photovoltaic agricultural generator unit that can be used on agriculture plantation, has not both interfered with the normal growth of crops, it is also ensured that the normal operation of small-scale agricultural machinery.Can be directly anchored on photovoltaic bracket and use lithium battery to reduce operating expenses as electrical storage device increases service life.Photovoltaic bracket uses earth anchorage, will not produce any building waste.Fixed support is built also without on arable land exclusively for trapping lamp.
