In the winter of Zhangbei Bashang, the sky is clean, and rows of fans rotate. Zhangbei Wind Power Project as a supporting project of the Beijing Winter Olympics, let the Zhangbei dam "wind" blows to Beijing, lighting up the Winter Olympics venue. Among the many wind power projects in Zhangbei County, TebeA New Energy not only undertakes and participates in the construction of large wind power projects, but also provides TSVG dynamic reactive power compensation and harmonic control devices for many projects, ensuring that Zhangbei's green energy is continuously and stably sent to the Beijing Winter Olympics venues.

Online intelligent redundancy technology, safe and reliable

Zhangbei Wind Power Project is characterized by a complex supporting power supply structure and a high degree of electricity electronization on the power supply side and the grid side. Therefore, coordination between the power supply and the grid is needed to improve the absorption capacity of new energy and the safe operation level of the power system. Tbea New Energy TSVG has the comprehensive management ability of voltage, reactive power and power quality. It has successfully passed the network source coordination test and verification of the new energy station's access to Zhangbei flexible DC Project, and supports the smooth delivery of new energy green energy of Zhangbei flexible DC project.

The temperature in Zhangbei region in winter is around minus 25°C for a long time, and the temperature difference between day and night is around 25°C. During the Winter Olympics, the temperature is low and may even suffer from severe cold weather. Tbea New Energy TSVG adopts online intelligent redundancy technology to realize automatic removal of fault modules and ensure that the TSVG module will not stop if it fails. The high protection level (IP65) and wide temperature (-40℃ ~ +55℃) adaptability of the product ensure the SVG equipment operating ability in harsh environment, and comprehensively improve the operation reliability of TSVG equipment.

Unique frequency conversion modulation technology, reduce power loss

In the context of building a new power system with new energy as the main body, a high proportion of renewable energy is connected to the power grid. On this basis, how to achieve flexible interaction and complementary interaction between source and load side, SVG plays a crucial role. Tbea new energy TSVG adopts the green design concept of energy saving and consumption reduction. The heat dissipation mode of the equipment adopts the advanced water-cooled heat dissipation mode. According to the real-time operating temperature of IGBT, the heat dissipation power is adjusted by frequency conversion, which maximizes the heat dissipation efficiency and ensures the economic operation of TSVG (rated loss < 0.8%).

As a national million-level wind energy construction base, Zhangjiakou can develop more than 40 million kW of wind energy resources reserves. With the continuous improvement of the construction of intelligent new energy transmission channels, Zhangjiakou has become the only selected wind power parity online demonstration area in Hebei Province. Tbea undertook the EPC construction of 100MW wind power parity Online demonstration project in Zhangbei County of Zhangjiakou City and 100MW wind power project of Zhangjiakou New Energy Research and Development Test and Certification Center. After the project is connected to the grid, the annual generating capacity of the project reaches 268.5 million kWh, and the cumulative contribution of clean energy within the whole life cycle of the project reaches 1,0285,000 kWh.

As the world's outstanding green smart energy service provider, TBEA takes building a zero-carbon earth as its goal, and insists on using green electricity to energize green electricity, promoting the energy revolution of the whole society, and building a beautiful green home for mankind. This green energy project for the Beijing Winter Olympics not only shows the technology and responsibility of China's new energy enterprises, but also shows the determination and confidence of China to achieve the goal of "double carbon". I wish the Beijing Winter Olympics a complete success.

寒冬时节的张北坝上，碧空如洗，一排排风机转动。张北风电项目作为北京冬奥会的配套项目，让张北坝上的“风”吹到了北京，点亮冬奥会场。而此次张北县多个风电项目中，特变电工新能源不仅承接参与建设大型风电项目，也为多个项目提供TSVG动态无功补偿及谐波治理装置，确保张北的绿色能源持续稳定送往北京冬奥场馆。

在线智能冗余技术，安全可靠

张北风电项目具有配套电源结构复杂，电源侧和电网侧设备高度电力电子化等特点，因此需要电源与电网的协调配合，提高新能源消纳能力和电力系统安全运行水平。特变电工新能源TSVG具备电压、无功及电能质量综合治理能力，顺利通过新能源场站接入张北柔性直流工程网源协调试验测试验证，支撑张北柔性直流工程新能源绿色电能的顺利送出。

张北地区冬天气温长期在零下25°C左右，昼夜温差在25度左右，在冬奥会期间气温较低，甚至可能遭遇严寒天气。特变电工新能源TSVG采用在线智能冗余技术，实现故障模块自动切除，确保TSVG模块故障不停机。产品的高防护等级（IP65）及宽温度（-40℃～+55℃）适应性设计，确保SVG设备在恶劣环境中运行能力，全方位提升TSVG设备运行可靠性。

独有变频调制技术，降低功率损耗

在构建以新能源为主体的新型电力系统时代背景下，可再生能源高比例接入电网，而如何在此基础上实现源端与负荷端的柔性互动、互补互济，SVG的作用显得至关重要。特变电工新能源TSVG采用节能降耗的绿色设计理念，设备散热方式采用先进的水冷散热方式，根据IGBT实时运行温度，变频调节散热功率，最大限度提高了散热效率，确保了TSVG的经济运行（额定损耗＜0.8%）。

作为国家百万级风能建设基地，张家口可开发风能资源储量在4000万千瓦以上，随着新能源智能化输电通道建设的不断完善，张家口成为河北省唯一入选风电平价上网示范地区。特变电工新能源承接建设了张家口市张北县100MW风电平价上网示范项目、张家口新能源研发试验认证中心100MW风电项目的EPC建设工程，项目并网后年均发电量达26850万kWh，项目全生命周期内累计可贡献清洁能源达1028500万kWh。
