Photovoltaic Grid-Connected Cabinet

In today's increasingly environmentally conscious society, solar power generation, as a clean energy source, is becoming more and more popular. As a key equipment in solar power generation systems, the role of photovoltaic grid connected cabinets is becoming increasingly prominent. It is designed specifically for grid connection of electrical energy, connecting the generator system and the power grid system. It not only installs comprehensive grid protection devices, but also has multiple functions such as voltage loss detection and opening, voltage detection and closing, overcurrent protection, etc. In addition, the photovoltaic grid connected cabinet can also measure the total amount of photovoltaic power generation, simplify the troubleshooting process, and thus improve the safety and economic benefits of the power generation system. It is widely applicable to photovoltaic power generation systems and perfectly combined with photovoltaic grid connected inverters, providing a complete solution for photovoltaic power generation.

The core function of photovoltaic grid connected cabinet:

1.Electricity transmission and grid connection: Its primary task is to smoothly transmit the electricity generated by the photovoltaic power generation system to the grid, achieving grid connection and laying the foundation for electricity contribution and electricity revenue.

2.Electricity monitoring and detection: Photovoltaic grid connected cabinets not only transmit electricity, but also undertake the responsibility of fine management of the power grid. It can maximize the output of electrical energy from the power generation system and monitor key parameters of the power grid in real time, such as voltage, current, and power, to ensure the stable operation of the power grid.

3.Induced current control: In addition, the photovoltaic grid connected cabinet also has the function of induced current control, which enables it to effectively limit the induced current, thereby protecting the equipment and its circuits and significantly improving the safety of the system.

Key equipment inside the new energy grid connected cabinet:

1. Anti islanding protection device in the new energy grid connected cabinet. This device plays a crucial role in photovoltaic power plants. It can monitor key parameters such as voltage and frequency in real time. Once abnormalities are detected, such as possible islanding, the warning mechanism will be immediately activated and the grid connection point switch will be quickly cut off, ensuring that the photovoltaic power station can be quickly and safely decoupled from the grid. This series of actions not only ensures the stable operation of the power system, but also gains valuable response time for operation and maintenance personnel.

2. Class A power quality online monitoring device. The Class A power quality monitoring device has comprehensive functions, not only including core functions such as harmonic analysis, flicker measurement, and power measurement, but also capable of comprehensive monitoring and evaluation of power quality. In addition, it also integrates diverse communication interfaces, making it easy to build a power quality monitoring and management system through flexible communication methods.
