锅炉跟随控制的构成——兼论直接能量平衡控制的动态特性

Synthesis of The Boiler Fellow Control (BFC) and The Dynamic Characteristics of Direct Energy Balance(DEB)

直接能量平衡控制法在国内大型火电机组中已开始使用 ,它对锅炉汽压对象特性的作用十分显著。文中以火电机组的锅炉跟随控制系统为基础 ,分析了直接能量平衡控制法对锅炉汽压对象特性的影响 ,以30 0 MW机组为例 ,通过仿真说明了直接能量平衡控制法比其它形式的复合型锅炉跟随控制系统对负荷扰动和燃料扰动具有更好的稳定性。图 6表 1参

The coordinate control of the Direct Energy Balance (DEB) has just been used among fire generator unit in the country, it is very efficient that the DEB affects the steam characteristics of boiler. Based on the Boiler Fellow Control (BFC) of the fire generator, this paper analyses that the DEB affects the steam characteristics. With the example of 300MW unit, the result of simulation shows that the DEB has a better performance of the load disturbance and fuel disturbance than the others do. Figs 6, table 1 and refs 8.
