摘　　要：云南电网在实现异步联网运行后,各并网运行的大型水电机组一次调频动作频繁,机组在一次调频调节过程当中,其实际积分电量受各种因素的影响而不达标,水电厂也因此受到考核。本文结合云南某大型水电机组的一次调频过程,对一次调频期间机组的积分电量展开研究,从机组实际运行现状出发揭示其原因,并对两个细则辅助服务一次调频考核的完善提出建议。After Yunnan power grid has realized asynchronous operation,many hydropower units’primary frequency modulation move more frequently.In the process of primary frequency modulation,the actual integrated power of the units is not up to standard due to the influence of various factors,so the hydropower plants are also assessed.Based on the primary frequency regulation process of a large hydropower unit in Yunnan Province,this paper studies the integral power of the unit during the primary frequency modulation,reveals the reasons from the actual operation status of the unit,and it provides some suggestions on the improvement of the primary frequency modulation assessment of the two detailed rules auxiliary services.
