Distributed PV integrated control system

The invention relates to a distributed photovoltaic power generation integrated control system. A low-voltage microgrid control terminal and a low-voltage power quality control device are accessed into a low-voltage grid, and a medium-voltage power quality control device and a medium-voltage distributed power generation control terminal are accessed into a medium-voltage grid. The distributed photovoltaic power generation integrated control system has the advantages that by means of the distributed photovoltaic power generation integrated control system, a distributed photovoltaic power supply serves as standby energy, power supply blockage can be alleviated, margin of a power distribution network is enlarged, power supply reliability is improved remarkably, controllable idle-work output capability is provided, busbar voltage level is maintained, voltage drop is alleviated, large-area power outage is avoided, and capacity of the existing power quality regulation device can be reduced remarkably when the distributed photovoltaic power generation integrated control system and the existing power quality regulation device of the power distribution network are combined to operate to perform idle-work regulation or harmonic wave inhibition.
