摘要
随着空冷技术在发电机组的广泛应用,其控制系统的研究越来越重要。以直接空冷为研究对象,重点阐述空冷背压的控制,尤其背压变化时,对系统参数以及协调控制所造成的影响。结合实际运行机组的背压控制特点,从背压影响因素出发,逐一分析其控制难点,探讨相应控制策略。表明可以通过各因素分析,制定措施,最终消除背压变化对系统的影响。
With the wide application of ACC in power units,the research on the control system becomes more and more important. This paper focuses on the control of air cooling back pressure, especially when the pressure changes, the effects on the system parameter and coordinated control. According to the actual control characteristics and influence factors of back pressure, difficulty and corresponding cortrol strategy are analyzed. The influence of the change of back pressure on the system can be eliminated by analyzing the influencing factors and making measures.
