亚临界600MW机组高压加热器退出故障分析及其对策
摘要
通过对陕西国华锦界能源有限责任公司亚临界600MW机组中2次高压加热器事故退出的分析
提出了高压加热器事故退出时采用串级三冲量控制方案
其控制汽包水位较采用西门子公司的单级三冲量方案更有效。给出了运行操作中的防范措施。
Abstract
This paper analyzes two breakdown faults of the high pressure heater in a sub-critical 600 MW generating unit of Shaanxi Guohua Jinjie Energy Co.Ltd.
and suggests adopting serial three-impulse control scheme as this breakdown fault happens.This serial three-impulse control scheme is more effective compared with the Siemens' single-level three-impulse scheme.In addition
