Photovoltaic Power Generation Grid Connection System Solution

    For the full-capacity grid-connected photovoltaic system, the solar-generated electricity is inverted and then stepped up to 10kV via a 0.5/10kV box transformer. It is then connected to the user's 10kV incoming line through a 10kV cable T-connection to achieve grid integration. The grid connection system plan from the power supply bureau has not been obtained yet, and further detailed design must be based on the approval of the grid connection system by the power supply company.

Main Electrical Connection Diagram of the Photovoltaic Power Generation System

  Modules are connected in parallel to the inverter to generate alternating current, which is then collected by AC combiner boxes and fed into the step-up transformer. After being stepped up to 10kV, the power is distributed through four high-voltage switchgear cabinets for photovoltaic grid connection (including the photovoltaic step-up transformer switchgear, photovoltaic metering cabinet, photovoltaic grid connection cabinet, and another photovoltaic grid connection cabinet).
