What are the main electrical wiring schemes for photovoltaic power plants?

Photovoltaic power station main electrical wiring is the main booster main electrical connection station, a wiring or electrical, refers to the transformer, circuit breaker, isolating switch, lightning arrester, transformer, capacitor, bus, power cable, a main electrical equipment, in accordance with the order of connection to the circuit, usually using single graph.

During the electrical primary design, the factors such as power supply reliability, operation flexibility, operation simplicity, economy and easy expansion should be fully considered.

Typical electrical main wiring can be broadly divided into two categories: according to the number of access points can be divided into busbar connection mode (that is, single access point) and no bus connection mode (multiple access points). Among them, the bus connection mode is divided into single (double) bus and single (double) bus section two ways, without bus connection mode can be divided into external bridge connection mode and internal bridge connection mode.
