The Tianhuangping pumped storage hydroelectric project is the biggest of its kind in Asia. It provides valuable cover for demand surges in the central coastal region, including high growth Shanghai. The new plant plays a vital role in stabilising the entire East China Power Grid, improving the quality of the power supply in east China, and ensuring the safe operation of the nuclear power stations in the surrounding areas.

Two pump storage reservoirs are about 1km apart and have a difference in elevation of m. The lower reservoir is located on the Daxi Creek branch of the Xitiao river and the upper reservoir is an artificial basin cut deep into the mountains.

Two 7m-diameter conduits from the upper reservoir each branch into three 3. The maximum generating head is The first generator began operation in October , later than planned, partly as a result of a major landslide the previous year. The remaining five MW units came online in stages during and To minimise the amount of on-site installation, the six pump turbines were pre-assembled prior to delivery and were then split into two for shipment.

The synchronous generators are of suspended vertical-shaft construction, with the thrust bearing above the rotor to allow better access for inspection and repair as well as reducing thrust bearing loss. The generator set is totally enclosed within a reinforced concrete housing. Cooling air is circulated by the self-pumping action of the rotor rim and fans and the air coolers are located outside the stator frame.

EDF assisted in studies to optimise overall plant performance. A key requirement was to fill the upper reservoir in a shorter time than normal, requiring a low ratio of turbine output to pump input. Care in design was needed to meet a t weight limit for transportation and to ensure the unit could be taken through a narrow access tunnel with a tight bend and could be maneuvered into its final position.

Four rectifier bridges supply the rated excitation current of around 1,A at V. The voltage regulation system uses two fully redundant digital voltage regulator and sequencer units of type GMR3 in hot standby configuration. Both provide full current and voltage regulation as well as system control, including devices for dynamic braking.

Elin co-operated with Elsag Bailey in Canada on the control system supply, acting as sub-supplier for hardware and programme implementation. Dual redundant fibre optic cable and microwave radio links connect critical local control units such as that at the upper reservoir. The main control room has two fully redundant operator stations, each equipped with two monitors. There is also a mosaic plant overview panel to give a full plant overview and emergency back-up control.

Many of the local control units have operator stations to provide local control capability, and there is also an engineering and maintenance terminal.

A separate sequence of events recording system has been installed to document fault sequences down to a resolution of 1ms. The control system software runs the plant with minimum intervention in normal operation. The setpoint can be either a fixed value as forecast over time daily load curve or as a cyclic value generated by an Energy Management System in the dispatch centre. The software includes an expert system for optimising energy production; based on software developed in Austria by Tauernplan Consulting.

A full control system training simulator, complete with software to simulate typical fault conditions, has also been supplied as part of the control system contract. This increased the installed hydropower capacity by 8. China has some 15,MW of pumped-storage hydro plants planned, in operation or construction.

Tianhuangping is the largest pumped storage scheme in Asia, and the third largest in the world. GE Hydro supplied the generator motors. Elin was responsible for design and delivery of components including excitation equipment, electrical protection, the control system for the power station, and the associated kV SF6 substation, generator bus ducts and starting frequency converter.

Other electromechanical equipment sub-suppliers provided circuit breakers and starting systems for the units in pump mode. In this report, we look at the 30 big tech themes for , identifying winners and losers for each theme.

Power Generation Equipment Testing

Compressed-air energy storage CAES is a way to store energy generated at one time for use at another time using compressed air. At utility scale, energy generated during periods of low energy demand off-peak can be released to meet higher-demand peak load periods. CAES systems can have a vital impact in making sure that the electricity demands can be met at peak hours. Large-scale applications must conserve the heat energy associated with compressing air; dissipating heat lowers the energy efficiency of the storage system. Compression of air creates heat; the air is warmer after compression.

Pairing solar energy resources with batteries is a winning solution. It allows utilities to store excess power when the sun is shining but demand is low, and use it when the sun sets but demand is high. Legislative policies, such as renewable portfolio standards RPSs , can play an integral role in state efforts to diversify the energy mix, promote economic development, and reduce emissions.

The electricity grid is a complex system in which power supply and demand must be equal at any given moment. Constant adjustments to the supply are needed for predictable changes in demand, such as the daily patterns of human activity, as well as unexpected changes from equipment overloads and storms. Energy storage plays an important role in this balancing act and helps to create a more flexible and reliable grid system. For example, when there is more supply than demand, such as during the night when low-cost power plants continue to operate, the excess electricity generation can be used to power storage devices.

Numerous well-engineered auxiliary systems are required to ensure safe, reliable and efficient operation of hydropower plants. All components and systems are integrated seamless into overall plant concepts and designs. Our engineers are highly competent in all domains, and we use our worldwide extensive experience from project execution to develop optimized solutions for all project-specific requirements. In addition, numerous electrical energy systems and components are an integral part of the station supply of hydropower plants. The operation of a power plant requires electrical energy, e.

Electric Thermal Energy Storage

Его любимым развлечением было подключаться к ее компьютеру, якобы для того, чтобы проверить совместимость оборудования. Сьюзан это выводило из себя, однако она была слишком самолюбива, чтобы пожаловаться на него Стратмору. Проще было его игнорировать.

Хейл подошел к буфету, с грохотом открыл решетчатую дверцу, достал из холодильника пластиковую упаковку тофу, соевого творога, и сунул в рот несколько кусочков белой студенистой массы. Затем облокотился о плиту, поправил широкие серые брюки и крахмальную рубашку. - И долго ты собираешься здесь сидеть.

Ну и проваливай, пидор. Беккер посмотрел на нее внимательнее. К ней как-то не шло сквернословие - как неуместны сточные воды в хрустальном графине. Но, приглядевшись, он убедился, что она вовсе не такая изысканная особа, как ему показалось вначале.

Теперь, считали они, им уже нечего было опасаться, представ перед Большим жюри, услышать собственный записанный на пленку голос как доказательство давно забытого телефонного разговора, перехваченного спутником АНБ.

Никогда еще получение разведывательной информации не было столь легким делом. Шифры, перехваченные АНБ, вводились в ТРАНСТЕКСТ и через несколько минуты выплевывались из машины в виде открытого текста. Секретов отныне больше не существовало.

Она кружила по пустому кабинету, все еще не преодолев ужас, который вызвало у нее общение с Хейлом. Надо выбираться из шифровалки. Черт с ней, с Цифровой крепостью.

- С ним все будет в порядке.

Интересно, о чем он. У Бринкерхоффа подогнулись колени. Он не мог понять, почему Мидж всегда права. Он не заметил отражения, мелькнувшего за оконным стеклом рядом с.

Крупная фигура возникла в дверях директорского кабинета.

Танкадо прижал изуродованную руку к груди с выражением недоумения и ужаса на лице. - Вы можете заметить, - продолжал Смит, - что взгляд его устремлен. Он ни разу не посмотрел по сторонам. - Это так важно? - полувопросительно произнес Джабба. - Очень важно, - сказал Смит.

 - Если бы Танкадо подозревал некий подвох, он инстинктивно стал бы искать глазами убийцу.

Пожилой человек вдруг поднялся и куда-то побежал, видимо, вызвать скорую. Танкадо явно терял последние силы, но по-прежнему совал кольцо прямо в лицо тучному господину. Тот протянул руку, взял Танкадо за запястье, поддерживая остававшуюся на весу руку умирающего.
