增加一条昼夜电能消耗曲线,就能进一步提高汽轮机运行的机动性,同时实际上也迫切需要提高这种机动性。正如研究所表明的:在运行机动性方面,操作人员操作的准确性和及时性的概率随着机组单机功率的增加而下降,在控制任务和过程明显复杂化的同时,监视和控制设备也大大增加。 此外,在电力系统中,大的原子能电站机组数目的增加,就势必要它们参加调频,并且要在正常工况下,使机组发出有效功率,在事故时要能保持电力系统的稳定。
The addition of a diurnal energy consumption curve will further improve the maneuverability of the steam turbine while at the same time there is an urgent need to improve this maneuverability. As the Institute has shown, in terms of operational maneuverability, the probability of operator accuracy and timeliness decreases as stand-alone unit power increases. As control tasks and processes become significantly more complicated, monitoring and control equipment is also significantly greater increase. In addition, in the power system, the increase of the number of large atomic power station units will inevitably require them to participate in frequency modulation, and under normal operating conditions, the unit should send out effective power to maintain the stability of the power system in the event of an accident.
