| 摘 要： | CFB(循环流化床)锅炉是新一代高效、低污染清洁型燃烧锅炉,在国内得到广泛应用。但CFB锅炉发电机组自动控制系统尤其是协调控制系统设计不成熟,投运一直是个难题。在分析河北省保定热电厂原协调控制策略的基础上提出了改进措施:完善了一次调频功能;设计了汽机侧的“压力偏差回拉功率”回路,以限制汽机侧调门的动作速率;将直接能量平衡策略改为间接能量平衡策略;为克服锅炉燃料调节的滞后性使用了燃料前馈。最后对改进后系统的调节性能进行了评价。 |
| 关 键 词： | CFB锅炉 CCS 调频 间接能量平衡 燃料前馈 |

| Abstract: | Based on the analysis of the original CCS of Baoding Cogeneration Power Plant,some improvements are presented.The frequency regulation has been modified;The "press deviation dragging load"loop has been designed in order to limit the response speed of turbine valve;The direct Energy Balance(DEB) strategy has been replaced by Indirect Energy Balance(IEB) strategy;Fuel feedforward has been used to compensate the time delay of the CFB boiler.The performance of the improved CCS is also evaluated. |
| Keywords: | CFB boiler CCS frequency regulation Indirect Energy Balance(IEB) fuel feedforward |
