Large solar photovoltaic modules type concentrated grid photovoltaic power station configuration process

Photovoltaic (pv) grid power generation system, can be divided into the grid side and generation (dg) in two kinds of user side. The former general and branch in the low voltage side, 380/220V) With an emphasis on spontaneous self-use; Or the medium voltage side ( 10kV、35kV) With an emphasis on nearby is given. Usually can be countercurrent photovoltaic (pv) grid system, and some

photovoltaic (pv) grid power generation system can be divided into two types: the user side side of the grid and generation (dg). The former generally in low voltage side, 380/220 v) Spontaneous for private use. Or the medium voltage side ( 10kV、35kV) , mainly for the use of nearby. It is usually a counter-current photovoltaic (pv) grid system, some systems need to reverse power protection ( Is the current photovoltaic (pv) grid system) 。 Grid type photovoltaic power station has two types: large centralized user side side of the grid and generation (dg). 10 mw and above most of the power grid in power generation side. Using 'the current' grid. Electric current is unidirectional, not for personal use and measuring '' net table. Only grid electricity price is given. Usually, the connection of 110 kv and 220 kv high-voltage output power. Its output characteristic is a change with power grid frequency and voltage current source. The power factor is 1, does not provide reactive power. Large centralized grid photovoltaic power station is mainly composed of photovoltaic array, variable power control device and grid access system ( Step-up transformer, ac breaker, measuring equipment) And so on. In addition to the main equipment, photovoltaic power station is equipped with photovoltaic array DC lightning protection box, ac and DC power distribution system.
