Every Structural Health Monitoring company boasts specific projects in its portfolio. The Kozloduy nuclear power plant is one of those specific Digitex projects where hard work intertwines with creativity. The result of this effort is a nuclear power plant with an alarming system based on vibration monitoring triggers.

That’s what Digitex proudly achieved – to craft a specific solution for Kozloduy to meet all structural and people safety standards.

Stay tuned to see how we did it.

The Concept Behind the Solution

For this purpose, we chose the most appropriate vibration monitoring equipement – a sophisticated 12-channel RTR system. We meticulously tailored it for monitoring the structural response of the High-Oscillation Generation (HOG) site.

This vibration monitoring and quick response system shows how Digitex can customize the SHM solution according to specific user needs. In this case, Digitex implemented a comprehensive sentry system and enhanced it with seismic data visualization and processing, real-time alerts, seismic event archiving, and much more.

Real-Time Alerts and Safety Measures

Key elements of this system include standard GPS timing, ensuring synchronized data collection across all channels. In the event of an earthquake, the sentry system is programmed to send automatic SMS and email notifications to a list of subscribed users, ensuring effective communication and quick response during critical events.

Seismic Data Visualization and Processing

Digitex designed the system to automatically turn off heavy machinery at the site during seismic events, minimizing potential hazards. The recorded seismic events through the vibration monitoring equipment are visualized on a dedicated website. Then, users can initiate automatic processing to extract multiple parameters.

Some of the parameters that the experts extract from a Digitex mems vibration sensor are the Peak Acceleration (PA), Peak Velocity (PV), Peak Displacement (PD), Fast Fourier Transform (FFT), Cumulative Absolute Velocity (CAV), etc.

Comprehensive Seismic Event Archiving

Another critical feature is the automatic report generation in the form of PDF documents, providing detailed analysis of the seismic events. An SQL database is available for careful archiving of the sentry system data, enabling an easy and chronological search option for all recorded seismic events via the web server.

This comprehensive approach to seismic monitoring showcases Digitex’s dedication to innovation in structural health monitoring, ensuring the Kozloduy Nuclear Power Plant operates with the highest safety standards.

Conclusion

Once again, Digitex proved that their vibration monitoring equipement together with their alarming system it’s an all-out safety solution for any structure. That’s why we seperated this nuclear power plant as an excellent case study of how critical role can a mems vibration sensor hav in a quick response systems.
