摘要
Abstract
An unplanned shutdown incident occurred at a steel plant's captive power plant due to a failure in the steam turbine's TSI system vibration module.A thorough analysis was con-ducted to identify the root cause of the failure and evaluate potential risks in the TSI system.Based on the findings,targeted upgrades were implemented,including hardware and software enhance-ments to the TSI system,along with optimized sensor point arrangement.Following the modifica-tions,comprehensive functional testing was performed under the improved trip logic to verify the ac-curacy of all monitoring points and ensure that shutdown protection commands were triggered promptly and precisely according to the protection setpoints.These measures have effectively im-proved the safety,operational efficiency,and stability of the steam turbine generator unit.关键词
