Energy shortage, energy security, rapid growth of energy prices and environmental pollution have become the primary issues restricting social development in many regions. The application and development of global energy are facing a huge crisis. To solve this series of problems, large-scale development and utilization of green energy is one of the important means. The use of green energy can, on the one hand, effectively alleviate energy shortages and environmental pollution caused by the use of traditional fossil fuels, and on the other hand, it can also promote the development of the local economy.
The solar photovoltaic power generation system uses the principle of photovoltaic effect. It is a power generation system that directly converts solar radiation energy into electrical energy. It mainly transmits the electricity generated by the solar cell array directly to the AC power grid through the photovoltaic inverter, or directly supplies the AC load with the electricity generated by the solar energy through the photovoltaic inverter.
Facing the current situation:
1. Large floor area
2. Low conversion efficiency
3. Intermittent work
4. Largely affected by climate and environmental factors
5. Strong regional dependence

Photovoltaic solutions:
Photovoltaic solar power generation box-type substation is a product independently developed by our company based on the latest international technology and domestic power supply requirements.
Integrating the box-type inverter station and the box-type booster station into one, it can complete the photovoltaic DC input to the three-phase high-voltage AC output in one box, optimizing the system structure, eliminating duplication of functions, making the structure more reasonable, the functions more complete, and the volume It is more compact, and all the equipment is constructed and debugged in a factory, and the cables and cable trenches between the original box-type inverter station and the box-type booster station are eliminated. This type of box transformer can be called a "box transformer with inverter function" and is divided into 35kV European-style integrated photovoltaic power station and 35kV American-style integrated photovoltaic power station.
35kV European-style integrated photovoltaic power station
The voltage level of the split transformer is 35kV. It integrates the inverter module and the boost module. It directly inverts and boosts the DC power generated by the photovoltaic modules to the 35kV voltage level and then integrates it into the photovoltaic boost box transformer of the power grid. The box layout is in the shape of a "mesh" structure, which is divided into a high-voltage room, a transformer room, and an inverter room. The overall structure is compact and has complete functions. The box has strong anti-corrosion capabilities and good environmental adaptability. It is easy to install on site and only requires prefabricated foundations. Yes, it greatly improves on-site work efficiency.
