國(guó)際技術(shù)集團(tuán)安德里茨與歐洲建筑集團(tuán)STRABAG組成財(cái)團(tuán)，與迪拜電力和水務(wù)局（DEWA）簽訂了一份合同，為Hatta抽水蓄能電站提供全部電氣和水力機(jī)械設(shè)備，該電站位于迪拜市東南140公里的哈吉爾山（Hajar Mountains）。
預(yù)計(jì)將于2024年第一季度啟動(dòng)。包含電氣和水力機(jī)械設(shè)備的合同價(jià)值超過1億歐元。
設(shè)備有多大？注意看中間的人參照物
安德里茨將為兩臺(tái)125 MW Francis型水泵水輪機(jī)提供機(jī)電設(shè)備，該水輪機(jī)配有交流勵(lì)磁發(fā)電機(jī)和輔助系統(tǒng)，所有閘門和垃圾箱，320 m壓力管道，主進(jìn)水閥，主電源變壓器，GIS開關(guān)站和高壓電用于將新電廠連接到國(guó)家電網(wǎng)的電纜。為保證水輪機(jī)特性，安德里茨將在自己的測(cè)試實(shí)驗(yàn)室中進(jìn)行詳細(xì)的模型測(cè)試。
Hatta將是阿拉伯半島同類項(xiàng)目中的第一個(gè)。最終構(gòu)想是基于靠近現(xiàn)有水庫的豎井式發(fā)電站，能夠在6個(gè)小時(shí)內(nèi)提供250 MW的功率。由于儲(chǔ)存容量相對(duì)有限，在循環(huán)過程中可用的壓頭將在175至125 m之間大幅變化。為了克服揚(yáng)程的這種大幅度變化，同時(shí)保證機(jī)組在整個(gè)循環(huán)中保持高效率運(yùn)行，兩個(gè)水泵水輪機(jī)組均配備了交流勵(lì)磁發(fā)電機(jī)，從而使機(jī)組可以變速運(yùn)行。
迪拜的明確目標(biāo)是使酋長(zhǎng)國(guó)的能源結(jié)構(gòu)多樣化，到2050年將可再生能源的份額從目前的7％提高到75％。為了實(shí)現(xiàn)這一宏偉目標(biāo)，DEWA決定不僅增加可再生能源發(fā)電的份額例如光伏和風(fēng)能，還需要建設(shè)必要的水力發(fā)電設(shè)施，以平衡這些可再生能源的波動(dòng)性。
安德里茨是擁有這項(xiàng)特定技術(shù)項(xiàng)目經(jīng)驗(yàn)和專業(yè)知識(shí)的全球少數(shù)供應(yīng)商之一。對(duì)于安德里茨及其財(cái)團(tuán)合作伙伴而言，獲得這一訂單是一個(gè)非常重要的里程碑，因?yàn)檫@一享有盛譽(yù)的合同被認(rèn)為是DEWA和整個(gè)地區(qū)的燈塔項(xiàng)目。獲得這份合同，再次肯定了安德里茨在水力發(fā)電行業(yè)機(jī)電設(shè)備領(lǐng)先供應(yīng)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.
