In December 20th, the CHINT Baicheng project in Jilin Baicheng photovoltaic power generation application base was fully connected to the grid. The total installed capacity of the project is 100 MWP, of which 71.535 MWP adopts the versatrack flat and inclined single tracking support scheme provided by nengyao new energy solar, with a total of 25 standard square arrays. The versatrack tracking system of nengyao new energy is a multi row linkage mode. This project has designed 769 driving units, each standard driving unit is 10 rows, and each row is composed of 26 components.

Tailor made low temperature and high wind resistant products
Baicheng city is located in the northwest of Jilin Province, the west of Nenjiang plain and the east of Horqin grassland. The annual average temperature is 4.5 ℃, the minimum temperature is - 36.1 ℃, and the maximum wind speed can reach 35m / s. In view of the low temperature and high wind pressure environment of the project, nengyao new energy company, relying on its own proprietary technology advantages, has carried out detailed tracking scheme optimization and design work, and finally customized the project for customersHigher reliability, higher land use efficiency, higher power generation gain, less materials, faster construction speed and more convenient maintenance of power stationOne stop tracking support solution based on.
Considering that Baicheng is located in a high latitude area, in order to improve the power generation, nengyao new energy has innovatively applied the horizontal inclined single scheme in this project. In the aspects of wind load value, overall structure design and on-site construction service, the tracking support steel members fully consider the high wind pressure characteristics of the project site, and combined with the tracking support design and operation experience of the company in the areas with great wind pressure of previous projects, the structural scheme of the project is designed to ensure the reliability and stability of the project. Facts have proved that in the continuous gale from November 26 to 28, nengyao new energy support products withstood the test of extreme gale with the highest wind speed of 8.
At the same time, the project adopts the operation mechanism of “breeding base + photovoltaic power generation”, with photovoltaic power station built on the top and planting and breeding on the bottom, so as to realize the complementary of agriculture, animal husbandry and light, and improve the land utilization rate. When designing the support, nengyao new energy fully considered the needs of planting and b

Focus on providing stable and reliable intelligent tracking scheme
Nengyao new energy solar has always been committed to providing customers with stable and reliable photovoltaic tracking solutions. At present, the application scenarios of its products cover desert, Gobi, beach, mountain, hill, agricultural cultivated land, water surface and other landforms.
Different from the fixed support mainly considering steel processing, the technical threshold of tracking support in mechanical structure mainly lies in how to properly and accurately define the wind load of the support structure, and accurately load it into the tracking support structure model for verification and calculation. In recent years, relying on its own intellectual property technology, nengyao new energy has accumulated a lot of application experience in wind load calculation in the field of multi row linkage tracking support. Because the calculation is very complex, without years of technical accumulation, it is easy to cause design errors by simply imitating and copying mature products in the market, which will lead to the tracker not working on site, and in extreme cases, it will also cause serious accidents such as collapse.
"We have improved the wind load requirements of the project based on the mature products of the company, aiming at the demand of the project, and the maximum design wind pressure reaches level 11. At the same time, the key equipment components such as reducer, motor and bearing of the project have good low temperature resistance performance. " The project leader of Zhengtai Baicheng, energy company, said.
