中间再热汽轮机低载运行的静态相似准则和动态相似准则

The SSC and DSC of Low Load Operation of Reheat Steam Turbine

低载运行稳定性是中间再热汽轮机运行稳定性的关键所在,也是机组调节系统设计的重要依据。本文提出了静态相似准则SSC和动态相似准则DSC,它们把系统中众多的系统参数按一定规律组合起来,使系统得到相对的简化。通过SSC和DSC这两个综合指标的应用,不仅可为系统分析、系统调试和系统改进提供方便,而且可为系统与系统之间比较、系统设计的规范化创造有利条件。

Low load stability is the key point of operation stability of reheat steam turbine, it is also the main basis of the design of the control system. In this paper static similarity criterion (SSC) and dynamic similarity criterien (DSC) has been introduced. This method synthesize a numerous system paramrter according to certain rules, thus the system can be relatively aimplified. Through the application of SSC and DSC, it does not only facilitate the system analysis and system adjustment, but also help the comparison between different systems and design of standardization.
