Centralized ground photovoltaic power generation system solutions

Large-scale centralized photovoltaic power plant using centralized construction, centralized management, centralized transmission mode, make full use of Gobi, barren hills and other low utilization of land for construction. Power stations generally use the full Internet model, through the national benchmark price to obtain a stable income. Centralized power station with a single capacity of low investment costs, easy operation and maintenance management, income stability, etc., is the major companies can rest assured that holding the excellent assets.

1, photovoltaic field area:
  Centralized photovoltaic power plant photovoltaic area covers an area of ​​several hundred acres to several thousand acres, from the PV module, installation bracket, convergence box, box inverter and other major equipment components. The photovoltaic field is the core of the photovoltaic power plant, the field area of ​​the magnificent, able to build the company's image, brand promotion to provide quality material. I have completed the project performance of the total capacity of 330MW, covers an area of ​​9900 acres of ground-based centralized power plant, Asia and the world's largest single-cell photovoltaic power plant.




2,35KV high voltage switchgear:
  For the centralized ground power station, the main use of 35kV high voltage switchgear as the power station of the main collection and distribution equipment, the current Division I 35kV high voltage switchgear installation methods are concrete frame structure, steel structure, prefabricated 3, the Division I will be based on the specific needs of customers and power station construction cycle, select the appropriate installation, to complete the construction of the power station tailored.




3, the control room:
The central control room is the brain of the photovoltaic power plant, the total station power generation, power generation, all kinds of equipment running state, the key area of ​​video surveillance will be in the control room intuitive embodiment, combined with the current intelligent equipment, Customers provide fully automated operation and maintenance experience, and fully reduce the customer's labor costs.



4, step-up station, switch station:
 The power station, main transformer, reactive power compensation device and other major equipment, 10 ~ 30MW ground power station generally through the switch station 35kV grid, 30 ~ 200MW general Through the boost station boost to 110kV and network, more than 200MW 220kV voltage level can be considered grid.



5, photovoltaic power generation system topology:
  Centralized photovoltaic power plant with its core power generation components for the photovoltaic components, the light energy into electricity, through the inverter DC - AC conversion, the components of the DC into the transport and easy to use the exchange of electricity. Centralized photovoltaic power plant capacity is large, in order to reduce the collector loss, the inverter output voltage is generally increased to 35kV through the box to 35kV, 35kV switchgear through the 35kV grid, or after the main transformer after the second boost Through 110kV or even 220kV voltage level and network.



Product Features:
 1. Photovoltaic output stability, can take full advantage of solar radiation and electricity load is the peak peaking characteristics, play the role of peeling.
2. Operation mode is more flexible, can be reactive and voltage control, to participate in the grid frequency adjustment is also easier to achieve.
3. Construction period is short, the environment can adapt to a strong, do not need water, coal transportation and other raw materials to protect, low operating costs, easy centralized management, limited by the space, you can easily achieve expansion.
