power distribution solution
A photovoltaic (PV) step-up substation is a facility that converts the direct current (DC) electricity generated by PV power generation units into high-voltage alternating current (AC). Its core principle involves utilizing power equipment such as transformers and inverters to convert and boost the DC voltage.
Specifically, PV power generation units absorb solar energy through solar panels, converting light energy into DC electricity, which is then transmitted to the PV step-up substation. Within the substation, the DC voltage first needs to be increased. This is because the DC voltage generated by PV units is typically relatively low and insufficient for direct grid connection. Therefore, the PV step-up substation boosts the DC voltage via a transformer, enabling it to be fed into the grid.
