核电机组一次调频风险分析及优化

The Risk analysis and Optimization of Primary Frequency Regulation for Nuclear Power Plant

核电机组一次调频在保证核电的安全运行等方面起着重要的作用,因此,研究一次调频动作对汽轮机和反应堆带来何种危害是十分有必要的。针对机组在满功率状态情况下,研究一次调频动作的风险并对其进行分析、仿真,最后提出相应的优化方法。这种研究对核电机组避免此种情况下一次调频带来的动作风险有一定的指导意义,有利于核电的安全运行以及提高电网频率质量和安全稳定运行水平。

Primary frequency regulation of nuclear power unit is very important in ensuring the safe operation of nuclear power. Therefore, it is very necessary to study the effect of primary frequency modulation on steam turbine and the reactor. On the condition that nuclear power unit is in full power state, the risk of primary frequency regulation is analyzed and simulated, and the corresponding optimization methods are proposed. This study has a certain guiding significance in helping the nuclear power unit to avoid the risk of primary frequency regulation, and is conductive to the safe operation of nuclear power and improve the safe and stable operation of power grid frequence quality.
