机械补偿控制是一种先进的控制反应堆功率及轴向功率偏移的技术。由于功率控制系统和轴向偏移为两个独立的系统,为了避免不利的核峰值因子,最大限度减少功率和轴向偏移控制系统之间的互相干扰,业界普遍采用功率控制系统具有优先权的策略。基于对该策略的目的及实施方法的研究,提出一种改进方案。基于对安全相关影响、可实施性及性能的分析表明该改进能以极小的代价提高控制系统的时间响应特性,具有较高的实施价值。
Mechanical compensation control is an advanced technology for controlling reactor power and axial power offset. Due to the power control system and axial offset into two independent systems, in order to avoid unfavorable peak crest factor and minimize mutual interference between power and axial offset control system, the power control system is widely used in the industry. Strategy. Based on the purpose of this strategy and its implementation, this paper proposes an improved solution. Based on the impact on safety, the feasibility and performance analysis shows that the improvement can improve the time response of the control system with little cost and has high implementation value.
