Explanation of technical terms for photovoltaic power station access to the power grid
What is a photovoltaic power plant?
It refers to a power generation system that uses the photogenerated volt effect of solar cells to directly convert solar radiation energy into electrical energy, generally including transformers, inverters, related balance system components (BOS) and solar cell arrays.
What is a grid-connected photovoltaic power station?
Photovoltaic power plants that are directly or indirectly connected to the utility grid operation.
What is a public connection point?
Connections of more than one user in the power system.
What is a PV power plant grid-connected point?
The grid-connected point of a photovoltaic power station with a booster station refers to the bus or node on the high-voltage side of the booster station, and the grid-connected point of a photovoltaic power station without a booster station refers to the output summary point of the photovoltaic power station.
What is the transmission line of photovoltaic power station?
Transmission lines from the grid connection point of a photovoltaic power plant to a public connection point.
What is the active power of a photovoltaic power station?
The active power input from the photovoltaic power station to the grid-connected point of the photovoltaic power station.
What is the reactive power of photovoltaic power station?
The reactive power input from the photovoltaic power station to the grid-connected point of the photovoltaic power station.
What is active power variation?
The difference between the maximum and minimum active power of a photovoltaic power station within a certain time interval.
What is LVRT?
When the voltage drop of the grid-connected point of the photovoltaic power station is caused by a power system accident or disturbance, the photovoltaic power station can ensure the continuous operation without going off the grid within a certain voltage drop range and time interval.
