As part of our project, our partner Voith designed and installed a cavitation monitoring system at our demonstration site Valeira in Portugal. The new system contributes to improved real-time monitoring and operational efficiency.
Two cavitation sensors per unit were installed to measure and monitor cavitation conditions in real time. The system also features a data acquisition system which processes and records data from the sensors, ensuring efficient storage and analysis of information. Additionally, it acquires five additional analogue signals from each unit: active power, speed, gate opening, blade opening and net head. Finally, the system includes a dedicated monitoring PC for data collection and analysis, meaning all monitoring can be done locally. The cavitation status results are stored in the Cloud, where they are available and visualized for remote access and analysis.
