三峡水电站水轮发电机的性能和结构特点评析

三峡左岸电站水轮发电机组经过长期的攻关研究，在工程初步设计批准时已确定机容量为７００ＭＷ。通过国际招标，左岸１４台机组于１９９７年９月分别签订了合同。其中６台发电机授予ＶＧＳ联营体。８台授予ＡＢＢ公司。通过三次设计联络会，已确定电磁设计和结构设计。这里主要就这两家著名公司的发电机设计方案和结构特点进行评析。

Evaluation on the performances and structure characteristics of the hydro-generators of the Three Gorges Project

Through the long term study, the hydro generating units of the Three Gorges left bank power plant with the installed capacity of 700 MW per unit have been determined and approved in the preliminary design of the Project With the international competitive bidding, the contracts of 14 generating units for the left bank power plant have been respectively signed in September 1997 Of them, 6 power generators were awarded to VGS joint venture (including the companies of Voith in German, GE in Canada and Siemens in German), and another 8 power generators were awarded to ABB Company The electromagnetic design and structural design have been determined This paper describes the evaluation of the design scheme and structural characteristics of power generators made by such two companies
