Multi-combination device of large-scale solar photovoltaic off-grid power generation system

Abstract

The invention discloses a multi-combination device of a large-scale solar photovoltaic off-grid power generation system. The multi-combination device is characterized by being composed of n off-grid power generation units (1), a low-voltage power distribution cabinet (2), a transformer (3) and an alternating load (4), wherein n is larger than or equal to 1 and is a positive integer. The off-grid power generation units (1) are connected with the low-voltage power distribution cabinet (2), the low-voltage power distribution cabinet (2) is connected with the transformer (3), and the transformer (3) is connected with the alternating load (4). According to the multi-combination device of the large-scale solar photovoltaic off-grid power generation system, abundant solar energy in the remote areas can be fully converted into electric energy needed by people in the life of the remote areas, the multi-combination mode can adapt to various environments, the solar energy can be utilized to the maximum degree, and unified management is convenient. Thus, the multi-combination device is an ideal power source in the non-electricity areas.

Description

technical field [0001] The invention belongs to a solar photovoltaic power generation system device, in particular to a multi-combination device of a large-scale solar photovoltaic off-grid power generation system. Background technique [0002] With the development of science and technology, electric energy has widely penetrated into various fields of human activities. However, there are still nearly 2 billion people in the world who do not have access to electricity, and a considerable number of them live in remote areas with underdeveloped economies. Conventional power supply to solve electricity problems. These remote areas without electricity are often very rich in solar energy resources. The use of solar photovoltaic off-grid power generation can effectively solve the difficulty of extending conventional power sources and the problem of electricity consumption. Herdsmen's home lighting has a small power generation and a simple system, which cannot fully meet the rapid ...

[0002] With the development of science and technology, electric energy has widely penetrated into various fields of human activities. However, there are still nearly 2 billion people in the world who do not have access to electricity, and a considerable number of them live in remote areas with underdeveloped economies. Conventional power supply to solve electricity problems

These remote areas without electricity are often very rich in solar energy resources. The use of solar photovoltaic off-grid power generation can effectively solve the difficulty of extending conventional power sources and the problem of electricity consumption. Herdsmen's home lighting, the power generated is very small and the system is simple, which cannot fully meet the rapid improvement of people's life and large power consumption, and the system design is not reasonable enough, which is not conducive to unified management and maintenance
