小型水电工程,集中了用感应电动机作异步发电机运行的优点,越来越引起兴趣。它虽然有些缺点,然而,它的结构坚固,制造经济,往往比普通同步发电机更易被选择。阐述了一些方法,按照这些方法,可以从电动特性推导出它的发电特性。 Small hydropower projects, focusing on the induction motor for asynchronous generator operation advantages, more and more aroused interest. Although it has some shortcomings, however, its structural rigidity and economy of manufacture are often easier to choose than conventional synchronous generators. Some methods are described, from which the power generation characteristics can be deduced from the electrodynamic characteristics.
