Description

A prefabricated substation for photovoltaic power generation

technical field

The utility model relates to the technical field of prefabricated substations, in particular to a prefabricated substation used for photovoltaic power generation.

Background technique

At present, there are three main forms of solar energy utilization: photothermal utilization, photochemical conversion utilization, and photovoltaic power generation utilization. Among them, photovoltaic power generation utilization takes electric energy as the final form, which has the advantage of extremely convenient transmission. It has the irreplaceable advantages of the first two, and the reserves of raw material silicon for solar cells are very rich. With the continuous improvement of the conversion efficiency of solar cells and the continuous decline of production costs, solar photovoltaic power generation will occupy the future development of energy, environment and human society. The photovoltaic cell power generation has two working modes: off-grid system (independent power station) and grid-connected system (mains grid-connected power station). The step-up transformer is directly fed into the power grid, which can greatly reduce the storage capacity of the battery. In the construction of a solar power station, except for the solar panel array (ie, photovoltaic modules), which can be directly installed in the open air, the rest of the equipment needs to be installed indoors.
