1000MW机组滑参数停机的运行控制及分析

The operation control and analysis of sliding parameter shutdown of a 1000 MW ultra-supercritical power unit

滑参数停机能快速降低缸温,有利于尽快对汽轮机本体进行检修,本文介绍了广东粤电靖海发电有限公司2×1000MW超超临界机组典型的滑参数停机过程及曲线。通过对#4机滑参数停机的过程控制、参数变化曲线及出现的异常进行分析,探讨和总结出1000MW机组滑参数停机的操作思路、控制要点及滑停过程中的注意事项,对国内同类型机组以后的滑停操作具有重要的指导意义。

Shutdown in condition of sliding pressure operation can quickly make the temperature of cylinder lower, which makes it possible to maintain the turbine proper ASAP, This paper introduces the process and curve of sliding parameter shutdown of the guangdong yudean jing hai power genera- tion co. , LTD. 2 × 1000 mw ultra supercritical unit. Through the analysis for process control, pa- rameter change curve and the emergence of sliding parameter shutdown of #4 unit, Discussed and summarized the operating ideas, control key points and matters needing attention of sliding parameter shutdown, it is a good reference to other same power plants.
