Fluent在水轮机模拟中的应用

关键词:水电,Fluent,水轮机
简介:Computer simulation helped engineers make design changes that will generate revenue gains of up to $ 5 million (CAN) in 12 hydropower turbines. By shifting the maximum efficiency point to raise the power output by 7.8 megawatts and by raising the weighted efficiency of the turbine by 1.6%, the changes will produce revenue gains of between $200,000 to $500,000 per year for each turbine. The exact amount depends on the grid demand. These revenue gains have already been validated in one turbine and plans are being made to implement them on the other eleven. These gains were made by m
odifying the runner at the blade trailing edge to eliminate a large eddy in the draft tube elbow that was discovered to be reducing efficiency of theturbines. The eddy was discovered and the design changes validated by using computational fluid dynamics (CFD) to provide researchers with a clear understanding of fluid flows throughout the turbine. Hydro-Québec is a world leader in generating green energy, with over 31,400 MW of installed capacity in 1998 and also ranks among North America’s largest distributors of energy. It serves 3.5 million residential, commercial, institutional and industrial customers in Québec. In addition, it supplies nine municipal systems, one regional cooperative and some 15 electric utilities in the Northeastern United
States, Ontario and New Brunswick. Since obtaining  a marketer’s license from the Federal Energy Regulatory Commission, it also makes direct sales, at market prices, to American power wholesalers, including public utilities, municipalities, resellers, and large industrial consumers in the United States. Its 1998 sales totaled 161.4 TWh, with Québec markets accounting for more than 88% (142.8 TWh) and sales outside Québec for nearly 11.5%. The company is a publicly owned company with a single shareholder, the Québec government.
