| 摘 要： | 真空是机组运行监视的主要参数之一,它关系到机组的安垒运行,决定了机组的理想焓降、发电效率和出力能力.在以往的机组控制中,仅把真空作为机组的保护参数,而没有将真空变化对控制参数的影响考虑在内,使得机组在真空不同时控制调节品质相差较多.本文介绍了通过试验方法获取真空改变对机组运行状态的影响数据,增加协调控制中对真空的修正部分达到控制优化目的试验过程. |

The Correction Research and Application of Change of Vacuum in Condenser on Coordi-Nate Control Method in Power Plant |
|
| Abstract: | Vacuity is one of the key parameters in unit's operation mode. It concerns unit's safe to power plant, which decides the ideal enthalpy drop,the power generation efficiency, the power generation capacity in power plant.Formerly, vacuity is only considered as a parameter of unit's protection, and its change influence into control is not considered. Thus, the performance of unit's control varies a lot to different vacuity. By analyzing the data of vacuity to the operation in power plant and adding the correction to vacuity, this paper presents a new method to improve control performance. |
