Domestic photovoltaic control system

Abstract

The invention discloses a domestic photovoltaic control system which comprises a rotating frame, a solar panel, a charge-discharge controller, a storage battery and a photovoltaic inverter. The solar panel is reversibly arranged on the rotating frame, a first motor drives the rotating frame to rotate, a second motor drives the solar panel to turn over, a solar tracker is arranged at the center of the surface of the solar panel in a matching manner and controls the first motor and the second motor to work, so that the solar panel obtains the largest optical radiation orthographic area, solar energy is received by as much as possible and efficiently collected and used, a three-phase main reactor and a three-phase auxiliary reactor share a middle yoke, the sectional area of the middle yoke is specifically designed, so that the sectional area of the middle yoke can be decreased, material cost is reduced, temperature rise of the shared middle yoke can meet requirements, noise can be reduced, and overall efficiency can be improved.

Description

technical field [0001] The invention relates to photovoltaic technology, in particular to a household photovoltaic control system. Background technique [0002] As a new energy source, solar energy is inexhaustible and inexhaustible. At the same time, because solar energy is a clean energy source, it will not produce waste residue, waste water, waste gas, and noise during development and utilization, and will not affect the ecology. Balanced, it will never cause pollution and public nuisance, so it is widely favored by people today when environmental protection is advocated. Solar power generation is a common way of utilizing solar energy. The current solar power generation uses large-scale power stations for solar power generation. Large-scale solar power stations are only suitable for public use due to their large scale, high cost, and large footprint. Electricity generation, not suitable for ordinary household use.

Solar power generation is a common way of utilizing solar energy. The current solar power generation uses large-scale power stations for solar power generation. Due to their large scale, high cost and large footprint, large-scale solar power stations are only suitable for public use. Electricity generation, not suitable for ordinary household use

[0003] For ordinary families, electricity expenses have become an indispensable part, and for some families, it has become a heavy burden

Especially in some sparsely populated places, due to the underdeveloped public resources, many places do not have public power facilities for power supply, so modern popular and convenient household appliances such as TVs, washing machines, refrigerators, and rice cookers cannot be used at all, which greatly affects Limit the improvement of people's quality of life

Therefore, looking for alternative renewable energy and reducing the consumption of conventional energy has become a difficult problem that people have been eager to solve but have not yet been effectively solved.

At present, the key problem encountered in solar photovoltaic power generation is how to efficiently collect and utilize solar energy. The phase of the alternating current generated by the inversion of the direct current generated by the photovoltaic cell is different from that of the grid voltage, how to adjust it, and how to eliminate the inverted alternating current. High-order harmonics, so as not to bring pollution to the grid, the above problems make it difficult to use the two AC power sources in superposition

In addition, at present, two independent three-phase reactors are generally used in photovoltaic inverters to form filter lines, which not only has high material costs, but also makes the overall volume large, takes up a lot of space, and complex and cumbersome assembly and operation, which obviously hinders the current The development of photovoltaic grid-connected power generation
