摘要
为了分析水电机组在不同水电站、不同负荷、不同水头的一次调频特性,寻找对水电机组一次调频最不利的工况点,文中建立了单管单机带与不带调压室2类情况下,水电机组一次调频数值仿真模型,分析水电机组处于2种情况下,不同水电站、不同负荷、不同水头时的不同水力特性一次调频性能情况,获得一次调频影响规律及是否设置调压室会影响水电机组的一次调频性能,为保证水电机组的正常稳定运行提供技术保障。
In order to analyze the primary frequency modulation characteristics of hydropower units in different hydropower stations,different loads and different water heads,the most unfavorable working conditions for primary frequency modulation of hydropower units are found.In this paper,a numerical simulation model of primary frequency modulation of hydropower units is established under the condition of single tube single machine belt and no surge chamber.
