On November 21, Beijing time, the Qatar World Cup opened at the Gulf Stadium. More than 60,000 spectators attended the grand opening ceremony with singing and dancing. Then the host Qatar and Ecuador competed for the opening match here.

The once high-spirited football stars unconsciously stepped into the ranks of veterans, we are looking forward to their "Ragnarok" battle on the World Cup stage, looking forward to their last blooming.

This World Cup is about to stage the "Ragnarok", in addition to these well-known stars, what else has attracted much attention? From the stadium to the water supply network to the power supply, Chinese enterprises have participated in the design, construction and construction, providing strong support for the Qatar World Cup.

In the field of new energy power generation in Qatar, the 800 MW photovoltaic power station in Alcazar, Qatar, constructed by Guizhou Engineering Co., Ltd. of China Electric Power Construction Group, all adopts the 1500V inverter solution of sunshine power supply, among which the solution of Liangxin Customized Intelligent Electrical System solves the problems of sand and dust high temperature encountered in desert photovoltaic power station, to ensure the stable operation of Alcazar Photovoltaic Power Station in the harsh environment of high temperature and strong wind and sand in the Middle East.

The power station is currently the third largest single photovoltaic power station in the world. It can generate about 1.8 billion kilowatts of green electricity annually, reduce about 900,000 tons of carbon emissions, and supply clean electricity for the 2022 Qatar World Cup venues, helping Qatar to fulfill its commitment to host the "Zero-Carbon World Cup".

During the construction of the project, the Alcazar Photovoltaic Power Station Project was located in the desert 80 kilometers west of Doha, the capital of Qatar, facing harsh conditions such as long-term high temperature of 50 degrees Celsius and frequent sandstorms. Liangxin Electrical provided customers with customized intelligent electrical system solutions through technological innovation, which solved the problem of developing desert photovoltaic power stations under high temperature and harsh conditions.

For example, Liangxin Electrical actively optimizes the heating and temperature rise of key current-carrying parts, alleviates the bottleneck of capacity reduction caused by high temperature environment, ensures long-term full-load operation of products under high temperature and closed conditions up to 70 C, and matches the design requirements of natural heat dissipation in scenarios such as inverters and low-voltage cabinets of box transformers.

The Alcazar Photovoltaic Power Station is a milestone in Qatar's new energy industry, and is also a strong witness to the success of Liangxin Electrical's products and solutions. In the future, Liangxin Electrical will help more countries reduce carbon emissions and achieve sustainable economic development.

北京时间11月21日零点，卡塔尔世界杯在海湾球场揭幕打响，超过6万名观众到场观看了载歌载舞的盛大开幕仪式，随后东道主卡塔尔队与厄瓜多尔队在这里展开了揭幕战的争夺。

曾经意气风发的足坛球星，不知不觉步入老将行列，期待他们在世界杯舞台上的“诸神黄昏”之战，期待他们的最后一次绽放。

本届世界杯即将上演的“诸神黄昏”，除了这些耳熟能详的球星，还有哪些备受瞩目呢？从比赛球场，到供水网络，再到电力保障，都有中国企业参与设计、施工、建设，为卡塔尔世界杯提供了有力支持。

在卡塔尔新能源发电领域，由中国电建集团贵州工程有限公司承建的卡塔尔阿尔卡萨800兆瓦光伏电站，全部采用阳光电源1500V逆变解决方案，其中，良信定制化智慧电气系统解决方案解决了荒漠光伏电站中遇到的沙尘高温等问题，保障阿尔卡萨光伏电站在中东高温、强风沙的恶劣环境中稳定运行。

该电站是目前全球第三大单体光伏电站，每年可产生约18亿千瓦绿色电力、减少约90万吨的碳排放，并为2022卡塔尔世界杯场馆供应清洁电力，助力卡塔尔兑现举办“零碳世界杯”承诺。

在项目建设期间，阿尔卡萨光伏电站项目位于卡塔尔首都多哈以西80公里的荒漠中，面临长期50℃高温和沙尘暴频发等恶劣条件，良信通过技术创新为客户提供定制化智慧电气系统解决方案，解决了高温严苛条件下开发荒漠光伏电站问题。

例如，良信主动优化关键载流件的发热温升，减轻因高温环境引发的降容瓶颈，确保产品在高达70℃的高温密闭条件下长期满载运行，匹配逆变器、箱变低压柜等场景自然散热的设计要求。

阿尔卡萨光伏电站打开了卡塔尔新能源的先河，具有里程碑式意义，同时也是良信产品及解决方案成功出海的有力见证，未来良信将助力更多国家降低碳排放量，实现经济可持续发展。
