The generator load bank can achieve reactive power compensation by adjusting the current phase and voltage amplitude, thereby improving the efficiency and reliability of the photovoltaic power generation system.
In the photovoltaic power generation system, due to the instability of solar energy and the influence of weather, the output voltage and current of the photovoltaic battery group will fluctuate, thereby affecting the efficiency and reliability of the photovoltaic power generation system. The generator load bank can achieve reactive power compensation by adjusting the current phase and voltage amplitude, thereby eliminating the reactive current in the power system and improving the efficiency and stability of the photovoltaic power generation system.
The application of the generator load bank in the photovoltaic power generation system mainly includes the following aspects:
Sunwin AC Charging Pile Test Device
