| 摘 要： | 研究主要介绍了燃气蒸汽联合循环发电站（combined cycle power plant，CCPP）在油气切换过程的氮气吹扫及氮气封堵中出现的氮气管网压力控制不稳定的问题。根据反馈、前馈控制原理，利用分散控制系统（distributed control system，DCS）技术和CCM Studio组态软件进行研究。通过多次试验分析比较，最终利用前馈-反馈复合控制技术对原氮气管网压力控制系统进行了优化，实现了氮气管网压力的稳定控制，满足了机组在各种工况下的运行条件，保证了CCPP的安全稳定。 |

| Abstract： | In this paper, the problem of nitrogen pipe network pressure control instability during nitrogen purge and nitrogen sealing in the oil and gas switching process was mainly introduced in gas-steam combined cycle power plant (CCPP). According to feedback and feedforward control principle, distributed control system (DCS) technology and CCM Studio configuration software were used for the research. Finally, through multiple experimental analysis and comparison, the nitrogen pipe network pressure control system was optimized by the feedforward-feedback composite control technology, and the pressure stability control of the nitrogen pipe network was realized. It met the operating conditions of the unit under various working conditions and ensured the safety and stability of CCPP. |
