摘　　要： 分析机组给水泵RB工况发生后机组减负荷速率及其它实际操作过程中设备、系统固有特性对汽包水位的影响因素,给出计算模型并应用实际运行数据进行计算,得出机组在给水RB工况发生时保证汽包水位在保护动作范围内的机组最小减负荷速率及实际操作注意事项。用分析计算结果指导机组2次给水泵RB工况的处理均获成功。 The paper analyzed the influencing factors of the rate of decrease in unit's load when the runback (RB) working condition of feed- water pump for 300 MW unit occurreel and the inherent charateristics of equipment and system in the other actual operation process on the drum's water level, gave the computation model and carried out the computation by using actual operation data, obtained the minimum rate of decrease in unit's load and matters needing attention in the actual operation while the drum's water level was ensured to be within the protective action scope when the RB working condition of feedwater pump occurred. The runback process of feedwater pump for 300 MW unit was fulfilled successfully two times by using the analysis and computation results.
