3 Terms and Definitions

The following terms and definitions are applicable to this technical guide.
3.1
PV power station
A large-scale PV power generation system consisted of one or more photovoltaic power subsystems, converting sunlight energy directly to electric energy.
3.2
Photovoltaic power subsystem
A system including (one or more) grid connection inverters and relevant BOS (components of balance system), as well as a solar-cell-array with one point of common coupling.
3.3
Active power of PV power station
Total active power output from PV power station.
3.4
Reactive power of PV power station
Total reactive power output from PV power station.
3.5
Power factor of PV power station
Power factor calculated by the total active power and total reactive power output from PV power station. The power factor (PF) shall be calculated by the following formula:
