近日，随着3号机组圆满通过168小时满负荷试运行，青海省投3×660兆瓦“上大压小”火电项目实现全容量投产。 这标志着国内首座高海拔地区高比例掺烧高碱煤的智慧型火力发电厂正式建成，也意味着由电建核电公司承建、上海电建公司承试的首个高原火电项目全面竣工。项目位于青海省西宁市大通县，是青海省“十四五”能源发展规划的重点工程，也是青海电网750千伏系统中容量最大、性能最优、智慧化程度最高的火电机组。

Recently, with the successful completion of the 168-hour full-load trial operation of Unit 3, the 3×660-megawatt "upgrading large capacity and reducing small capacity" thermal power project in Qinghai Province has achieved full-scale commissioning. This marks the official completion of the first intelligent thermal power plant in high-altitude areas that proportionally burns high-sulfur coal. It also signifies the full completion of the first plateau thermal power project constructed by China Power Construction Nuclear Power Company and tested by Shanghai Electric Construction Company. The project is located in Datong County, Xining City, Qinghai Province, and is a key project in Qinghai Province's "14th Five-Year Plan" for energy development. It is also the largest-capacity, highest-performance and most intelligent thermal power unit in the 750-kilovolt power grid of Qinghai Province.

项目自2023年9月19日主体工程开工以来，项目团队便直面“高海拔”与“设备基础利旧加固”两大核心技术挑战。 厂区地处高原，低气压、低含氧量的环境对设备稳定性提出了严苛要求；同时，在拆除原有5×125兆瓦机组基础上原址新建，场地狭小、基础处理复杂，加之冬期施工周期长、厂外管线穿越河流林区等困难，施工难度极大。

Since the main construction of the project began on September 19, 2023, the project team has been confronted with two core technical challenges: "high altitude" and "reusing and reinforcing the equipment foundation". The factory site is located in the plateau region, where the low air pressure and low oxygen content pose strict requirements for the stability of the equipment; at the same time, building a new facility on the original site after dismantling the existing 5×125-megawatt units, the site is small, the foundation treatment is complex, and the winter construction period is long, as well as difficulties such as pipeline crossing rivers and forest areas outside the factory, make the construction extremely challenging.

项目团队以“建精品、保行优、争国优”为目标，攻克一系列技术难关，先后实现了厂用电受电、汽轮机扣盖、锅炉水压、点火吹管、机组并网等多个重大节点“一次成功”。

The project team aimed at "building high-quality projects, ensuring excellent operation, and striving for national excellence". They overcame a series of technical challenges and successively achieved "first-time success" for several major milestones such as receiving factory power supply, closing the turbine cover, boiler water pressure test, ignition and blowpipe operation, and grid connection of the unit.

在技术攻坚与调试运营中，项目团队同步发挥了关键作用。 作为当前世界海拔最高的高比例掺烧高碱煤660兆瓦超超临界火电机组，项目集成了超超临界、一次再热、间接空冷等先进技术，并采用无氢、无燃油、无液氨的安全环保运行模式。

During the technological breakthrough and operation debugging phases, the project team played a crucial role. As the current world's highest-altitude power plant with a high proportion of high-sulfur coal combustion, this project integrates advanced technologies such as ultra-supercritical, once reheating, and indirect air cooling, and adopts a safe and environmentally friendly operation mode without hydrogen, fuel oil, or liquid ammonia.

调试期间，团队以标准化作业和高标准启动为保障，攻克了高海拔、高碱煤带来的运行适配难题，确保了3号机组试运全程工况稳定，实现“零非停、零隐患”投产。

During the debugging period, the team ensured the implementation of standardized operations and high standards of startup. They overcame the challenges of operating conditions in high-altitude and high-sodium coal environments, ensuring the stable operation of the 3rd unit throughout the trial run and achieving a successful commissioning with "zero unplanned stops and zero hidden dangers".

项目全容量投产后，总装机容量达1980兆瓦，年发电量超80亿千瓦时，预计每年可减排二氧化碳200万吨。 这一清洁高效火电项目的“压舱石”作用将充分释放，不仅可满足青海省全年居民用电需求，更将显著提升区域电网安全稳定水平和清洁能源消纳能力，为青海省构建新型电力系统、推动经济社会高质量发展提供坚实支撑，在雪域高原树起一座绿色能源的丰碑。

After the full-scale commissioning of the project, the total installed capacity reaches 1,980 megawatts, with an annual power generation exceeding 8 billion kilowatt-hours. It is estimated that it can reduce 2 million tons of carbon dioxide emissions annually. This clean and efficient thermal power project's "balancing stone" role will be fully unleashed. Not only can it meet the annual electricity demand of residents in Qinghai Province, but it will also significantly enhance the safety and stability of the regional power grid and the capacity for consuming clean energy. It will provide solid support for Qinghai Province in building a new power system and promoting high-quality economic development. It will erect a green energy monument on the snowy plateau.
