Online Monitoring Solution for Large Units

Large nuclear power units comprise reactors, steam turbines, generators, cooling systems and auxiliaries, with complex systems and stringent safety requirements. Continuous high-temperature, high-pressure and high-radiation operation causes wear, aging and parameter drift; a fault anywhere can threaten stability and safety. Accurate real-time monitoring of all operating conditions is therefore essential. This solution provides 24/7 multidimensional monitoring of vibration, displacement, temperature, pressure and critical components. Professional algorithms detect early risks and predict deterioration, enabling prompt warnings and response, improving reliability and reducing unplanned downtime and safety risks for long-term stable operation and intelligent O&M.

Monitoring Challenges

Manual Inspections and Insufficient Monitoring Dimensions

Manual checks and experience produce discontinuous, delayed data that misses early risks. Monitoring only vibration, temperature and a few other parameters without multidimensional fusion captures incomplete fault signatures and reduces diagnostic accuracy.

Disconnected Fault Management

Isolated system data prevents a closed loop from equipment condition through warning to response and makes fault trends difficult to predict.

Weak Warnings and Reactive Maintenance

Simple thresholds without intelligent models or trend analysis delay anomaly identification and generate many ineffective alarms. Scheduled maintenance and emergency repairs result in both over- and under-maintenance, risking unplanned downtime and production safety.

Closed Systems and Unsupported Maintenance Decisions

Closed interfaces and inconsistent protocols prevent integration with intelligent O&M and digital twin platforms. Without deterioration and remaining-life assessment, maintenance timing and spare-parts stocking depend on experience, keeping costs high.

Product Advantages

Operating-Condition Adaptability

Radiation-resistant, high-temperature-resistant and corrosion-resistant monitoring devices suit nuclear power's heat, radiation and heavy loads, withstanding strong radiation and vibration without data distortion.

Early Fault Detection and Accurate Localization

An intelligent diagnostic model library combines envelope analysis, spectral demodulation and trend prediction to extract fault features and calculate weights automatically. It accurately identifies bearing wear, rotor unbalance and insulation defects, providing advance warning and substantially reducing false and missed alarms.

Comprehensive Visualization

Waveforms, spectra, trends, bar charts and 3D digital twins display health, alarm levels, fault locations and development trends, enabling real-time visibility, historical traceability and anomaly replay for efficient management and decisions.
