基于人工智能技术的火电厂燃煤锅炉智能燃烧优化研究及应用

, 2019
为了降低火电厂燃煤锅炉的氮氧化合物排放浓度和锅炉煤耗，提出了样本增量量子神经网络和改进型量子蜂群算法。样本增量量子神经网络可以动态建立燃煤锅炉的氮氧化合物排放浓度和锅炉煤耗的综合模型，并且可实现模型滚动优化。基于建立的综合模型，通过应用改进型量子蜂群算法优化一二次风量、燃煤量和各二次风门开度来实现锅炉燃烧优化。基于上述两种方法，开发了一套燃煤锅炉智能燃烧优化软件，并应用于某热电厂330 MW锅炉上，测试结果表明，氮氧化合物排放浓度和锅炉煤耗均有不同程度的降低 ...

防火墙吸声特性对变电站噪声影响研究

Gaoya dianqi
通过对防火墙不同吸声特性下的变电站噪声进行预测，分析了高压变电站防火墙吸声特性对站内以及厂界噪声的影响，为新建变电站的站内优化布局和投运变电站的噪声治理提供了依据。以雄安某500 kV变电站为例，构建了变压器多点等效源模型对变电站噪声进行了仿真预测，并经过实际测量验证了预测结果的准确性；在此基础上，提出了两种防火墙吸声特性改进方案，并预测了不同方案与变电站不同位置处噪声衰减情况，验证了防火墙吸声特性对变电站噪声影响主要在防火墙两侧方向，并且提高防火墙中低频吸声性能对变电站降噪效果最为明显 ...
