压水反应堆负荷跟踪的最优控制

按照最优控制理论 ,把压水反应堆的负荷跟踪控制问题描述为一个非线性二次型最优控制问题。反应堆芯部模型采用了一维分布参数模型。为求解这个最优控制问题 ,提出了一个行之有效的最优控制算法DDPSR。研究结果表明 ,DDPSR不仅能在大的优化区间收敛 ,而且迭代次数极少 ,速度相当快 ;大型压水堆能够以最优方式负荷跟踪运行 ,且轴向偏移 (AO)始终满足工程实际要求 ,此外还对硼的控制特性进行了特别的讨论

Optimal Control of Load-Following Operations in a Pressurized Water Reactor

According to the optimal control theory, the problem of load following operation in a pressurized water reactor is formulated as a nonlinear quadratic optimal control problem. One dimensional core model is adopted. A successful optimization algorithm DDPSR is proposed to solving the obtained problem. The research results show that the DDPSR can converge with a long time interval and needs very small iteration number and computing time, and the practical reactor can be fairly operated in an optimal load following manner and axial offset satisfies the required value from beginning to end. Control characters of boron concentration are discussed specially.
