Sensors for Monitoring Hydroelectric Power Plants — Vibration Detection Solutions
IMI Sensors division offers advanced vibration monitoring instrumentation specifically engineered to detect faults in turbine generators used in hydroelectric power plants. Reliable vibration monitoring is critical for preventing catastrophic failures, maximizing efficiency, and extending the operational lifespan of hydroelectric systems.
How Hydroelectric Turbines Operate
In a typical hydroelectric power plant, water flows from the reservoir through a penstock and over the turbine runner. As the fast-moving water impacts the runner blades, it causes the turbine shaft to rotate. This rotation drives the generator shaft, ultimately producing electricity.
Hydroelectric turbines typically operate at slow rotational speeds—ranging from 75 to 1000 rpm. However, fluctuations in electricity demand often require turbines to run at partial load. This operation increases the risk of:
- Water pressure pulsations
- Turbulence
- Cavitation within the turbine
These disturbances contribute to errant vibrations that can fatigue and damage critical runner components over time.
Vibration Monitoring for Turbine and Generator Components
Beyond the runner, turbine and generator shafts and bearings are highly susceptible to vibration-based faults. Common vibration-related issues include:
- Shaft unbalance
- Coupling misalignment
- Bearing fatigue and overload
- Insufficient bearing lubrication
Without continuous monitoring, these hidden faults can cause severe machine degradation, unexpected downtime, or costly repairs.
IMI Sensors deliver high-accuracy vibration data that help maintenance teams quickly detect, diagnose, and respond to emerging issues—before they cause major disruptions.
