摘　　要：水电机组运行区划分对机组运行安全至关重要。针对改造后的2台150 MW轴流转桨式机组,根据积累的在线监测数据,以机组稳定性参数为主要依据,划分了机组运行区。结果表明,50~150 MW为改造后机组的稳定运行区,0~50 MW为限制运行区,改造后的机组满足相关标准中对轴流转桨式水轮机稳定运行范围的规定。结果可用于指导机组运行控制。The division of operating regions is crucial for the safe operation of hydroelectric units.Based on the accumulated online monitoring data and the stability parameters,the operating regions of two renovated Kaplan hydro-turbine units are determined.The results show that the stable operating region of the renovated units is 50~150 MW,and the restricted operating region is 0~50 MW.The renovated units fulfill the requirements on the stable operating regions of Kaplan hydro-turbine units in relevant standards.The results can be used to guide the operation and control of the units.
