Three Gorges power plant equipment


Resolution on the construction of Three Gorges Project. In the same year in July. The Chinese government approved the preliminary design of the Yangtze River Three Gorges Project. Xiling Gorge dam site is located in the middle of a more open three-Doo Town of Yichang City. Mainly by the Three Gorges Project dam and spillway weir structures, hydropower plants,[link widoczny dla zalogowanych], navigation structure and so on. Weir dam is a concrete gravity dam. Crest elevation of 185m. Dam axis length of 2309.5m. Spillway dam center. Normal water level 175m. Total storage capacity 39.3x109m3. Hydropower plant dam on both sides of the split behind the dam spillway. L4 units left plant installation. Right side of the plant installation l2 units. A total of 26 sets of 700MW hydroelectric units installed. Total 18200MW. Annual power 84.7x109kwh: navigation structures located on the left bank. A double and single level 5 lock the vertical ship lift. Enhance the 3000t class ship (total increase 11800t. Is the world's first generating unit in 2003. Then installed power each year completed in 4 .2009. Gorges Project Layout plans are as follows: Three Gorges Dam, due to natural conditions and the flood-based needs. Early Head 61.94m. later head for the 71.113m. a large head variation. rated head 8O.6m. to the turbine design more difficult. single-unit output 700bm.75r/min. turbine runner diameter nominal 9.85m,[link widoczny dla zalogowanych], is the world's largest Francis turbine runner. unit uses three guide bearing semi-umbrella structure. Thrust bearing load 5390t. as of today's world. generator rated output of 778MVA. the power factor of 0.9. To enhance high head turbine operation stability under. generator design maximum output 840MVA. can be run continuously. generator rated voltage 20KV. using water-cooled stator winding. rotor cooling air-cooled. generator stator base diameter of about 22m. stator core inner diameter of almost 19m. core height of 3m. is the world's largest. units in large parts of the strength and stiffness and thermal deformation of the structure to adapt to ensure the stable operation of units is an important factor. Single-unit re-6600t. is currently the world's largest hydropower units. l4 Three Gorges Left Bank in 1996 Taiwan International Tendering 700MW units. provisions of bidders for the technical and economic take full responsibility. must be qualified manufacturers in China joint design, technology transfer,[link widoczny dla zalogowanych], cooperation manufacturing. foreign large-scale hydropower equipment manufacturing consortium composed of five bids. selected Alstom and ABB awarded 8. Kvacmer and Harbin Electrical Machinery Plant and cooperation. by the GanadaGE and Voith.Siemens (VGS) 6 sets of winning. and Dongfang Electrical Machinery Plant cooperation. China is about sub- total 3O%. 1997 年 9 月 contract. has relatively smooth execution of the contract; Harbin Power, Tokyo Electric Power Company sent to join the pilot, co-design and technology transfer training. technology transfer to achieve the transfer of the Chinese software installed on your computer calculation of the same foreign After the inspection results and stable operation. Alstom & Kvaemer transfer of turbine design and manufacturing software 35 (including the Business Software l8 months). ABB sale generator design software 42 (including the Business Software l5 months). VGS transfer of turbine design and manufacturing software 25 ( l3 in which a commercial software). sale generator design software 38 (including commercial software lO a). the transfer of technology transfer to achieve the depth of the source of foreign own software. As HEC ten years, the East's power to carry out scientific and technological basis. digestion and absorption of imported technology is better. have mastered the design and model tests of hydraulic turbines, generators, electromagnetic design, large parts of strength stiffness calculation, calculation and experimental thrust bearing, shaft stability calculation, generators, ventilation and cooling calculations, special Key technology and other technologies. can be self-developed design. the transformation of adding test equipment,[link widoczny dla zalogowanych], welding and heat treatment equipment, large CNC machine tools and so on. so that with the development of domestic design and manufacture of large-scale hydropower equipment capacity. adapt to vigorously develop hydropower needs. Gorges projects progressed smoothly. l2 1994 officially started on l4 l1 8 March .1997 into the construction of the second phase of the river closure. Now the left bank of plant and spillway dam section has been poured into the pouring of concrete .2000 l10.130m elevation 548m3. again hydropower construction created a world record. Bu 6 ring volute complete installation and concrete pouring. main building 2 sets of 1200t crane and crew to be installed. can water power generation in 2003. the world's largest Three Gorges Hydropower Station was built in 2009.
