I Project Overview
1. Project Introduction:
It is one of the poverty alleviation demonstration power station projects planned by Ningxia Zhongwei. The project is located in the northwest of Zhongwei City. The project adopts a fixed bracket installation method and the total installed capacity is 30MW.
2. Construction Geological Conditions:
Ningxia is rich in solar energy resources, with the characteristics of high altitude, long sunshine time, high radiation intensity and high atmospheric transparency. It is one of the regions with the most abundant solar and thermal resources in my country.
The local area is dominated by sand dune geology, the terrain has a fall, the sandstorm is heavy, and the instantaneous wind speed is high.
I Project Features
1. Aiming at the fact that the project is located on the edge of the desert, we boldly carried out innovative attempts in environmental protection to fully optimize the effect of sand fixation, that is, plant low and cold-resistant green vegetation under the square array to reduce the surface temperature of the power station and reduce water evaporation. Strive to build the power station into a truly green environmental protection project.
2. The power generation of photovoltaic power plants is greatly affected by weather changes and other factors, and the output power fluctuates during the period of time. It should be distributed and connected to maximize local consumption and achieve a balance of supply and demand.
3. Heavy sand and high instantaneous wind speed will cause sand dunes to move and bring great difficulties to the measurement and positioning. GPS RTK technology and basic point conversion technology are used to complete the laying out of the foundation construction to ensure accuracy.
4. Taking into account factors such as self-weight, wind pressure, and underlying structure, the foundation of the photovoltaic module steel support is an independent foundation of cast-in-place reinforced concrete, and the strength of the foundation concrete is C30. All photovoltaic modules are installed in a fixed manner, and the sub-arrays are equipped with container-type inverter devices to complete the construction in the shortest time and reduce the damage to the ground vegetation.
