摘要
灯泡贯流式机组具有适用水头低、机组过流量大、效率高等特点,已广泛应用于开发低水头水力资源。针对灯泡贯流式机组运行过程中受水质、水中漂浮物、导叶与轮叶协联和气蚀、尾水位变化等影响使机组发电效率变化较大,提出了密切关注机组运行工况、优化调度以提高机组效率。
Bulb-type turbine is suitable to use under low head, big flow conditions and has high efficiency under these conditions. It is widely used in low-head hydropower stations. During operation bulb units are geratly effected by water quality, floating matters in the water, combination of guide vane and blade, their caoitation, and change of tailrace level. All above-mentioned can greatly influence the efficiency of generating unit. Some suggestions are proposed for improving the generating unit efficiency.
