摘　　要：一次调频是指电网的频率偏离额定值时,电网中机组的控制系统自动控制机组有功功率的增减,限制频率变化,使电网频率维持稳定的自动控制过程。一次调频回路一般是分为CCS一次调频回路和DEH一次调频,这两部分的调频回路共同作用,其中DEH一次调频快速动作,CCS一次调频最终稳定负荷。优化机组一次调频功能,使DEH一次调频的动作直接控制汽轮机调门,用于改变机组的负荷,使机组快速响应一次调频的需求;CCS一次调频最终稳定负荷,一次调频动作后相当于去调节负荷的设定值,并确保和DEH的作用方向相同最终稳定负荷到需要值,促使考核数据满足网调要求,提高机组涉网服务能力,减少考核扣罚金额。Primary frequency control refers towhen the frequency of the power grid deviates from the rated value,the control system of units in power grid and theactive power increase and decrease of active powerunitslimit the frequency change and maintain the stability of the power grid frequency. The primary frequency control loop is generally divided into CCS primary frequency modulation loop and DEH primary frequency modulation loop. These two parts of the frequency modulation loop work together,in which DEH primary frequency control acts quickly,and CCS primary frequency control final stable load. The primary frequency control function of the optimized unit makes the DEH primary frequency control action directly controling the steam turbine regulating valve to change the load of the unit,which is the demand of the unit to quickly respond to the primary frequency control. The CCS primary frequency control final stable load is equivalent to adjusting the set value of the load after the primary frequency control action,and ensures that the action direction is the same as that of DEH. The final stable load reaches the required value. It promotes the assessment data to meet the requirements of network adjustment,improves the network related service ability of the unit,and reducesthe amount of assessment deduction.
