摘　　要：灯泡贯流式水轮发电机作为一种专门应用于大流量、低水头的水轮机,由于其自身转动惯量小,机组结构和安装方式都与常规的混流式、冲击式水轮发电机之间存在着显著的差异。其配套的调速系统在电气控制策及液压控制回路上的部件配置与常规的水轮机相比都有所不同。文中针对南瑞集团公司电气控制所(以下简称南瑞电控所)所研制的贯流式水轮发电机调速系统,对其控制原理、配置设定和实际运用情况进行了阐述和说明。The bulb tubular turbine generator is used as a specialized high-volume, low-head water turbine type . Because of its small moment of inertia , the structure and the way of installation of generating units are different from that of the francis turbine and action turbine. Compared with the conventional water turbine, the present turbine is different in electrical control strategy of water turbine governor and configuration of the hydraulie system. This paper proposes a control theory and configurations of the bulb tubular turbine generator, and describes its practical operation in water power plants.
