摘要
舟坝电站水轮发电机组运行水头范围较宽,部分负荷工况低频水力振动区明显。为指导机组在全水头下的安全稳定运行,进行两台机组振动区的界定是必要的。
The operating head range of Zhouba hydrogenerating units is relatively wide, the hydraulic vibrations with low frequencies at partial loads regions can be obviously observed. In order to have a guidance for safe and stable operation in the full operating head range, it is necessary to determine the vibration regions for these two units.
