摘　　要：锅炉汽动给水泵和电动给水泵并列运行时,给水自动调节系统调节效果不理想是常规给水调节系统经常遇到的问题。通过对常规给水自动调节系统分析、研究后,提出了控制逻辑优化、改进措施,并在某600 MW机组上的进行了实际应用。运行实践表明,优化后的锅炉给水自动调节控制系统有效地改善了调节效果。When the turbine and the motor feed-water pumps running parallel, non-ideal feed- water auto modulating system＇s effect is the ordinary issue to the conventional feed-water modulating system. After systematic analysis and study of the water-feed modulating system, control logic optimization and its improvement measures are proposed. Modulating effects of the boiler＇s feed- water auto modulating control system are improved.
