国际技术集团安德里茨与欧洲建筑集团STRABAG组成财团，与迪拜电力和水务局（DEWA）签订了一份合同，为Hatta抽水蓄能电站提供全部电气和水力机械设备，该电站位于迪拜市东南140公里的哈吉尔山（Hajar Mountains）。
预计将于2024年第一季度启动。包含电气和水力机械设备的合同价值超过1亿欧元。
设备有多大？注意看中间的人参照物
安德里茨将为两台125 MW Francis型水泵水轮机提供机电设备，该水轮机配有交流励磁发电机和辅助系统，所有闸门和垃圾箱，320 m压力管道，主进水阀，主电源变压器，GIS开关站和高压电用于将新电厂连接到国家电网的电缆。为保证水轮机特性，安德里茨将在自己的测试实验室中进行详细的模型测试。
Hatta将是阿拉伯半岛同类项目中的第一个。最终构想是基于靠近现有水库的竖井式发电站，能够在6个小时内提供250 MW的功率。由于储存容量相对有限，在循环过程中可用的压头将在175至125 m之间大幅变化。为了克服扬程的这种大幅度变化，同时保证机组在整个循环中保持高效率运行，两个水泵水轮机组均配备了交流励磁发电机，从而使机组可以变速运行。
迪拜的明确目标是使酋长国的能源结构多样化，到2050年将可再生能源的份额从目前的7％提高到75％。为了实现这一宏伟目标，DEWA决定不仅增加可再生能源发电的份额例如光伏和风能，还需要建设必要的水力发电设施，以平衡这些可再生能源的波动性。
安德里茨是拥有这项特定技术项目经验和专业知识的全球少数供应商之一。对于安德里茨及其财团合作伙伴而言，获得这一订单是一个非常重要的里程碑，因为这一享有盛誉的合同被认为是DEWA和整个地区的灯塔项目。获得这份合同，再次肯定了安德里茨在水力发电行业机电设备领先供应商的地位。
International technology group ANDRITZ hassigned a contract – as part of a consortium with the European constructiongroup STRABAG – with Dubai Electricity and Water Authority (DEWA) to supply andcommission the entire electro- and hydro-mechanical equipment for the HattaPumped Storage Power Plant located in the Hajar Mountains 140 km southeast ofthe city of Dubai.
Startup is expected for the first quarterof 2024. The contract value for the electro- and hydro-mechanical equipment ismore than 100 million euros.
ANDRITZ will provide the electromechanicalequipment for two 125 MW Francis-type pump turbines with double-fedasynchronous generators and auxiliary systems, all gates and trashracks, 320 mof penstocks, main inlet valves, main power transformers, GIS switchyard, andhigh-voltage cables to connect the new power plant to the national grid. Adetailed model test to guarantee the characteristics of the turbine will beconducted in ANDRITZ’s own test laboratories.
Hatta will be the first project of its kindon the Arabian Peninsula. The final concept is based on a shaft-type powerhouseclose to the existing hydro reservoir, capable of providing 250 MW for sixhours. Due to the relatively limited reservoir capacity, the available headwill vary significantly between 175 and 125 m during the cycle. To overcomethis substantial variation in head but still keep the units running at a highefficiency level over the complete cycle, both pump turbine units are equippedwith double-fed asynchronous motor-generators, allowing the units to operate atvariable speed.
Dubai has the clear goal to diversify theemirate’s energy mix and increase the share of renewable energy from thecurrent level of 7 to 75% by 2050. To achieve this ambitious target, DEWAdecided not only to increase the share of power generation from renewablesources, like photovoltaics and wind power, but also to build the necessaryhydro-pumped storage capacity required to balance the volatility of theserenewable energy sources.
ANDRITZ is one of the few global suppliersto have reference projects and expertise for such specific technologies. Awardof this order is a very important milestone for ANDRITZ and its consortiumpartners because this prestigious contract is considered a lighthouse projectfor DEWA and the entire region. In securing this contract, ANDRITZ has onceagain confirmed its position as a leading supplier for electromechanicalequipment in the hydropower industry.
