摘　　要：本发明涉及一种智能反应堆控制方法，依次包括：一，采集参数；二，对反应堆的中子注量率进行采样；三，以计算时间间隔Δt对中子注量率进行平均处理，得到各时刻的平均中子注量率Φ；四，得到t时刻的中间变量；五，得到t时刻的反应性；六，设定t+1时刻的中子注量率期望值，得到t+1秒的中间变量；七，得到t+1时刻的虚拟反应性；八，得到t+1时刻的控制棒的调节量；九，得到驱动控制棒的步进电机动作的步数；本发明使得控制方式完全符合反应堆功率增长或衰减的客观规律，实际使用中可以按照预设的运行曲线快速达到稳定值，避免了超调引起的过冲和震荡，在稳定运行时，可以控制中子注量率稳定在0.3%以内。

主权项：1.智能反应堆控制方法，依次包括以下步骤：第一步，采集以下参数；λ_i-第i组缓发中子先驱核的衰变常数；单位为s^-1；共15组；β_eff-缓发中子总的有效份额；β_ieff-第i组缓发中子有效份额，共15组；Λ-中子每代时间；单位为s；Q-外中子源强度；单位为中子/s；γ_s-外中子源的相对价值；ε-外中子源的效率；K_h-驱动控制棒的步进电机的步长，单位为mm/步；中间变量 $<math> <mrow> <msub> <mi>A</mi> <mi>i</mi> </msub> <mo>=</mo> <msup> <mi>e</mi> <mrow> <mo>-</mo> <msub> <mi>λ</mi> <mi>i</mi> </msub> <mi>Δt</mi> </mrow> </msup> <mo>;</mo> </mrow></math>$ 中间变量 $<math> <mrow> <msub> <mi>B</mi> <mi>i</mi> </msub> <mo>=</mo> <msub> <mi>a</mi> <mi>i</mi> </msub> <mrow> <mo>(</mo> <mn>1</mn> <mo>-</mo> <mfrac> <mrow> <mn>1</mn> <mo>-</mo> <msup> <mi>e</mi> <mrow> <mo>-</mo> <msub> <mi>λ</mi> <mi>i</mi> </msub> <mi>Δt</mi> </mrow> </msup> </mrow> <msup> <mi>e</mi> <mrow> <msub> <mi>λ</mi> <mi>i</mi> </msub> <mi>Δt</mi> </mrow> </msup> </mfrac> <mo>)</mo> </mrow> <mo>;</mo> </mrow></math>$ 中间变量 $<math> <mrow> <msub> <mi>C</mi> <mi>i</mi> </msub> <mo>=</mo> <msub> <mi>a</mi> <mi>i</mi> </msub> <mrow> <mo>(</mo> <msup> <mi>e</mi> <mrow> <mo>-</mo> <msub> </p><p class='subject'><strong>关键词：</strong><b class='type_ico_id'></b>中子注量率中间变量 <b class='type_ico_id'></b>反应性反应堆功率 <b class='type_ico_id'></b>反应堆控制驱动控制棒步进电机采集参数计算时间客观规律平均处理 <b class='type_ico_id'></b>控制棒 <b class='type_ico_id'></b>稳定值采样 <b class='type_ico_id'></b>反应堆期望值衰减震荡虚拟智能 </p><p class='class'><strong>IPC专利分类号：</strong>G21C7/00(20060101);G21C7/08(20060101)</p>
