摘　　要：Gansa水电站已经投入运行50年以上,利用原有尾水管和蜗壳等埋入部件,对其它的老旧设备进行更新改造。通过流动解析技术预测水轮机效率特性和气蚀特性,完成了水轮机的性能设计。同时在结构设计上采用了水润滑导轴承、无供水机械密封、油电混合接力器、发电机塑料轴承等新技术。At Korea’s Gansa power plant, which has been more than 50 years of operation, embedded parts such as draft tubes and casings were retained, and other old machinery was replaced. Cavitation characteristics and efficiency characteristics of hydraulic turbines were calculated through flow analysis, and thereby conducting performance design surely. Simplification of maintenance was achieved through such measures as employing water-lubricated bearings, water-free mechanical seals and hybridization of guide blade operation for hydraulic turbines as well as employing plastic bearings for generators.
