摘　　要：随着核电机组装机容量在电网所占比例日益提升,核电机组的一次调频能力也越来越受到关注。但由于核电其潜在的放射性危害,必须时刻将核安全放在首位。因此,在开展核电机组一次调频相关工作时,必须同时兼顾一次调频性能及核电机组运行安全的要求。本文以方家山核电机组作为研究对象,详细阐述了该机组一次调频逻辑和参数调整优化过程及试验开展的情况,在保证机组运行安全情况下,为电网运行安全出力。As the installed capacity of nuclear power units takes up an increasing proportion of the grid,the primary frequency modulation capability of nuclear power units is also receiving increasing attention.However,due to the potential radiological hazards of nuclear power,nuclear safety must always be a top priority.Therefore,when carrying out work related to the primary frequency modulation of nuclear power units,it is important to take into account both the primary frequency modulation performance and the operational safety requirements of nuclear power units.This paper takes the Fangjiashan nuclear power unit as the research object and elaborates on the optimization process of the primary frequency regulation logic and parameter adjustment of the unit and the tests carried out to ensure the operational safety of the unit and contribute to the operational safety of the power grid.
