Turbine vibration issues frequently occur in sediment-rich environments, adversely affecting equipment operational stability and structural integrity. This study investigates vibration response characteristics under high-sediment conditions, develops real-time identification and segmented shutdown control logic based on PLC systems, analyzes key parameter settings and execution workflows, evaluates dynamic response performance of water-guiding mechanisms under PLC command-driven operations, and assesses the strategy’s effectiveness in suppressing vibration peaks and improving control efficiency. The findings provide practical pathways and technical support for vibration risk prevention and intelligent control strategies in complex hydraulic environments.
