介绍了某电厂机组的燃烧控制系统,对系统在运行中存在系统设计保守,RB动作大额度甩负荷造成不必要的减产以及启停时主汽压力偏差大等问题进行了分析,并提出相应的改进措施,避免了不必要的甩负荷现象。同时对改进后系统的性能改善做出了客观的评价。
The combustion control system of a power plant unit is introduced. The problems of conservative system design, unnecessary load reduction due to large load rejection of RB operation and large deviation of main steam pressure during start-stop are analyzed. The corresponding Improve measures to avoid unnecessary load shedding phenomenon. At the same time, the improved performance of the system made an objective evaluation.
