摘　　要：新建机组中大部分以超临界或超超临界直流机组为主,对机组自动化水平和安全性的要求也相应提高。针对600 MW超临界机组的特点,对高加出系后给机组带来的问题进行了探讨和详细分析,提出了改进和完善措施,使系统能满足高加出系时的机组正常安全运行要求,并通过试验进行了验证。Currently, the new units are mainly supercritical or ultra supercritical, which need safer and higher requirement for automation. Based on the characteristics of 600 MW supercritical units, this paper researches the problems which occurred after high-pressure heaters withdrew, and gives some suggestions to improve and refine the system. These improvements were passed by practical tests, and can be referrences for thermal engineers.
