| 摘 要： | 概述了国内外有关小型水电站变速发电技术的研究情况，分析了双馈异步发电和交流励磁变速发电技术的控制原理及其不同于传统同步发电机的控制特性，即可以通过调节励磁来独立调节发电机的有功与无功，分析表明：变速发电技术将大大降低水轮机的气蚀及泥沙磨损，提高转轮寿命，同时振动减小，效率也将有较大提高，在水力发电、潮汐发电、风力发电等领域有着广泛的应用。

| Abstract: | This paper introduces the research about the generating technology of velocity-varying system used in small hydropower stations.The control theory and performance of the two-feedback asynchronising generator and velocity-varying generating system with AC exciting are analysised. The new generating system can regulate the active and reactive power independently and will reduce the cavitation and abrasion of the hydraulic prime-mover. Also, the efficiency and reliability will be improved. The generating technology can be used in hydro power, wind power and tide power generating systems. |
