摘要:

轮发电机组稳定性关系着水电站的安全运行。通过开展机组全水头下稳定性试验获取振动、摆度、压力脉动等稳定性指标,分析某水电站在全水头下机组运行状态,判断机组稳定性指标是否满足标准规范。结合电站实际情况精细划分机组在全运行水头下的全负荷运行区域,为电站安全、高效、稳定运行提供科学依据。

Abstract:

The stability of hydraulic turbine generator units is the key to the safe operation of hydropower stations.Stability indicators, such as vibration, swing, pressure fluctuation and so on, were obtained by a stability test under full head. The operation status of a unit in a hydropower station under full head was analyzed to find out whether the stability indicators met the standards. Fine partition of full-load operation region under full head was made combining the actual status of the power plants, which provides scientific basis for safe, efficient and stable operation of power plants.
