Abstract
The present disclosure relates to a grid-tied photovoltaic power generation system, and particularly, to a grid-tied photovoltaic power generation system including a power maintaining unit configured to maintain power of a controller during an corresponding operation time of a photovoltaic system when power supply is stopped due to a fault generated in a grid, whereby power may be stably supplied to the controller and power of the controller may be maintained, designing of the photovoltaic system and setting of a connection to the grid may be simply and easily performed, a corresponding operation of the photovoltaic system may be controlled regarding the fault generated in the grid, and the fault generated in the grid may be accurately, appropriately, and effectively handled.
Claims9
A grid-tied photovoltaic power generation system comprising:
- a photovoltaic system tied to the grid and operated;
- and
- a controller started by electric power supplied from the grid to control an operation of the photovoltaic system,
- wherein the controller comprises a power maintaining unit configured to maintain electric power during a corresponding operation time of the photovoltaic system when a fault is generated in the grid so electric power supply from the grid is stopped;
- a switching mode power supply connected to the grid and configured to convert the electric power supplied from the grid into a starting electric power;
- and
- a control unit started by the starting electric power to control an operation of the photovoltaic system.
