Walking into Yajiang County, Ganzi Prefecture, Sichuan Province, on the western Sichuan Plateau at an altitude of more than 4000 meters, the world's largest water-light complementary power station, Yalong River Kola Photovoltaic Power Station, is under construction. As the world's largest and highest water-light complementary project, the Yalong River Kola Photovoltaic Power Station has an installed capacity of 1 million kilowatts and is scheduled to be connected to the grid in 2023, providing 2 billion degrees of clean electricity annually.

Extreme environment puts forward higher requirements for the reliability of products. Therefore, on the basis of fully investigating the performance, adaptability and reliability of products in high altitude extreme environment, Cora Photovoltaic Power Station compares and evaluates the project benefits of using different products, and finally adopts Trina Tracking Pioneer 2p bracket with intelligent control system. With the support of Trina patented spherical bearing and self-developed and self-produced controller low-temperature battery, Pioneer 2p bracket can perfectly cope with the geological problems of Cora Power Station and the risk of power generation benefit brought by low-temperature environment, and provide more stable and efficient support for the goal of water-light complementarity of Cora Power Station.

In addition, Trina tracking pioneer 2p bracket and intelligent tracking closed-loop control system integrate AI technology, so that the tracking bracket can independently analyze and identify the best tracking angle at every moment, and can also avoid the loss of power generation caused by front and back occlusion to the greatest extent, compared with the tracking bracket of ordinary algorithm, the power generation can be increased by more than 3%, helping the power station. Give full play to the power generation potential of photovoltaic power plants.

After reaching cooperation with Yalong River Kola Photovoltaic Power Station, Trina tracked the first time to implement precise measures to ensure the construction of the project. Faced with the steep terrain and winding roads in the western Sichuan Plateau, the members of Tianhe Tracking Team made full efforts to take the lead in formulating detailed solutions for product delivery, distribution, driver training and installation technology, so as to ensure that the installation of tracking brackets was carried out on time and in order, and completed the first set of tracking brackets on January 13, helping the project to achieve efficient and timely production.

Taking clean energy development as the main line and exploring the experience of water-light complementary development, Cora Photovoltaic Power Station is the first water-light complementary power station to start construction since the "14th Five-Year Plan" of Yalong River Basin Clean Energy Base. As the leader of multi-scenario solutions for large bases, Trina Solar will continue to install power stations on time and in order, and cooperate with Cora Photovoltaic Power Station to produce "photovoltaic + N" benefits. Cora Photovoltaic Power Station will become a new model for large-scale centralized development of green, clean and renewable energy in China, promote the governance of Shu and Xingchuan to a new level with the new mode of benefit-sharing of renewable energy development, and make positive contributions to the realization of China's "double carbon" goal and the construction of a "clean, low-carbon, safe and efficient" modern energy system.

走进四川省甘孜州雅江县，在海拔4000多米的川西高原上，全球最大的水光互补电站——雅砻江柯拉光伏电站正在火热建设中。作为全球最大、海拔最高的水光互补项目，雅砻江柯拉光伏电站装机规模达100万千瓦，计划在2023年全容量并网发电，预计每年可提供20亿度的清洁电能。

光伏支架作为光伏电站的重要组成部分，承载着光伏电站的发电主体，被称之为光伏电站的“脊梁”。柯拉光伏电站项目位于高寒高海拔地区，环境恶劣，高寒缺氧，条件艰苦。高海拔低温、高风速、山地起伏地形、硬质地质结构对跟踪支架产品和施工技术都有着巨大的挑战。

极端环境对产品的可靠性提出了更高的要求，因此，在充分考察了高海拔极端环境的产品性能、适配性和可靠性的基础上，柯拉光伏电站对照评比使用不同产品的项目收益，最终采用了搭配智能控制系统的天合跟踪开拓者2P支架。在天合专利的球形轴承和天合自研自产的控制器低温电池加持下，开拓者2P支架能够完美应对柯拉电站的地质问题和低温环境带来的发电效益风险，为柯拉电站的水光互补的目标提供提供更稳定更高效的支持。

另外，天合跟踪开拓者2P支架和智能跟踪闭环控制系统融合了AI技术，让跟踪支架可以自主分析识别每一刻的最佳跟踪角度，也可以最大程度规避前后遮挡造成的发电量损失，相比较于普通算法的跟踪支架，发电量可提升3%以上，帮助电站智能化发展，充分发挥光伏电站发电潜力。

在与雅砻江柯拉光伏电站达成合作后，天合跟踪第一时间精准施策保障项目建设。面对川西高原陡峭的地势和蜿蜒的道路，天合跟踪团队成员上足力量，冲锋在前，对产品交付方案、配送方案、司机培训、安装技术等方面制定了详细的解决方案，确保跟踪支架安装工作按时按序推进，并在1月13日完成首套跟踪支架的安装调试工作，助力项目实现高效如期投产。

以清洁能源开发为主线，探索水光互补开发经验，柯拉光伏电站是雅砻江流域清洁能源基地“十四五”以来首个开工建设的水光互补电站，作为大基地多场景解决方案领军者，天合光能将继续和助力电站按时按序安装，协同柯拉光伏电站产生“光伏+N”的效益。柯拉光伏电站将成为绿色清洁可再生能源大规模集中开发新的中国样板，以可再生能源开发利益共享新模式推动治蜀兴川再上新台阶，为我国“双碳”目标实现、构建“清洁低碳 安全高效”的现代能源体系做出积极贡献。
