Grid Connection Scheme for Concrete Roof Solar Power Generation System and Photovoltaic System Operation and Maintenance

Photovoltaic Power Generation Grid Connection System Plan

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

Main Wiring Diagram of the Photovoltaic Power Generation System

After the modules are connected in parallel to the inverter, alternating current is generated. It is then collected through an AC combiner box and connected to the step-up transformer, which boosts the voltage to 10kV. Four high-voltage switchgear cabinets are used for photovoltaic grid connection (photovoltaic step-up transformer switchgear cabinet, photovoltaic metering cabinet, photovoltaic grid connection cabinet, and photovoltaic grid connection cabinet).
