摘要
辐射能能够较快地反应燃料量及锅炉燃烧率的变化,因此将辐射能作为中间变量引入到机组的控制当中,会对整个发电厂的优化控制起到很大的作用。本文以主蒸汽压力为主调参数、炉膛辐射能为副调节参数进行研究,结果表明此串级控制具有可行性。
Radiant energy can reflect the change of the fuel quantity and the boliler combustion rate more fastly.So,to adopt radiant energy as a middle variable in the control unit can make an important role for optimal concrol in power plants.In this paper,the main steam pressure as primary adjusting parameter and the radiant energy of the furnace as the subsidiary parameter are studied.The result shows that this cascade control is feasible.
