摘要
对火电机组采用的直接能量平衡(DEB)协调控制系统以及发电自动控制(AGC)方式的响应特性及其影响因素进行分析,指出了采用AGC对火电机组进行控制与优化时应注意的问题,并提出了进一步提高负荷响应速度的主要途径,对华能上安电厂一单元2×350 MW机组分析与优化,实验结果表明,优化后的DEB控制方式达到了协调控制系统快速性和稳定性的要求。
The response characteristics and influencing factors of the direct energy balance ( DEB ) coordinated control system of automatic generation control (AGC) in fossil-fired generating unit have been analyzed. At the same time, the paper pointed out the questions on the AGC controlling in fossil-fired generating unit and the main methods to further raise load response speed. The experiment results show that the DEB control method reached the requirements of the load speed rate and stability of the 350 MW unit in Shangan power plant.
