摘要
混流式水轮机的水力稳定性与机组运行工况密切相关。以三峡电厂左岸3号机组稳定性试验数据为例,分析机组小负荷区、涡带振动区、大负荷运行区的运行稳定性,为保障机组安全稳定运行提供了实测依据和建议。
The hydraulic stability of Francis turbines is closely related to the operating conditions. Take the data from stability test for No. 3 unit in Three Gorges Hydropower Station as examples, the running stability in the low-load zone, vortex band vibration zone and high-road zone is analyzed respectively. The reference data and suggestions are offered for operating the unit safely and steadily.
