Nuclear Nuclear Turbine Generator has a clean, pollution-free advantages, as water, fire power supplement will moderate development in our country. Tepco cherish participation in Lingao Nuclear Power 90MW Class 2-pole turbogenerator division of manufacturing work, which gradually understand and master the giant nuclear power generator technology, familiar with nuclear power equipment management, quality control and core content of corporate culture and the gradual establishment of the contract . Seeking to participate in the follow-up of nuclear power engineering, master manufacturing technology for 1000MW nuclear power generator most part, to further improve the management level of nuclear power, nuclear power equipment to become qualified manufacturers.
Full air-cooled hydrogen-cooled turbogenerator and gas is a high-energy clean energy, have been discovered as a competitive advantage and develop China's western and eastern shallow water large gas fields, as well as liquefied natural gas prices on the world, a gas steam combined cycle power plant It will have a certain degree of development. This power plant emissions cleaner, short construction period, the unit can start and stop quickly peaking, the whole thermal efficiency up to 60%, is the world's fastest growing kind of power plants. It needs air or hydrogen-cooled turbogenerator whole, in order to simplify the structure and operation, to adapt to rapid start and stop demands. Tepco has been successfully designed and manufactured 60MW, 75MW air-cooled turbine generator, water-cooled screw unit is developing 125MW and above capacity and 200MW-class air-cooled hydrogen-cooled turbogenerator whole.
Hydraulics
(L) Computer fluid dynamic analysis (CFD) CFD technology is a powerful weapon of hydraulic turbine development, but also for the motor fan airfoil design optimization. Through years of hard work and perseverance, cooperation with Tsinghua University, Central China and other universities, as well as the introduction of the Three Gorges technology opportunities, TEPCO has a set of practical business and application software: I used a three-dimensional solid modeling DEAS, using k a. Turbulent model to calculate the three-dimensional viscous flow TASKFLOW, mesh generation ICEM, runner interaction design BBX, volute, diffuser, tail pipe geometric design MACROS, POSPROC flow analysis and performance prediction after treatment, partial load Tail pipe pressure pulsation amplitude and frequency estimate, the vanes force characteristic and fixed guide vanes double row Grilles loss estimates, volute loss estimates, large eddy simulation tail pipe performance prediction. Tepco hydraulic CAD and CFD technology has reached a very high level, with the help of such advanced tools, we developed a model of efficiency over 94 written, stability is better than imported technologies Francis runner, model efficiency axial flow runner It has reached more than 92%.
(2) The model of turbine design and manufacturing technology turbine design level model in the international side, the model runner manufacturing technology a major breakthrough, blades, crown and lower ring full CNC machining. Fixed guide vanes with a line cutting, volute and tail pipes can fill plastic, spiral also points up and down two CNC machining.
