Abstract

The application discloses a predictive generator corrosion state monitoring system based on isotope tracing and multi-factor fusion analysis, comprising a collection mechanism, a leakage tracing unit, a sensing unit and a comprehensive analysis and diagnosis unit. The leakage tracing unit is used for online measurement of deuterium / hydrogen isotope ratio of dissolved hydrogen in the cold water. The sensing unit is used for synchronous measurement of pH value, dissolved oxygen concentration and other water quality parameters of the water sample. The comprehensive analysis and diagnosis unit fuses the above measurement data, and through the built-in model, not only can the leakage hydrogen and the corrosion hydrogen be accurately distinguished, but also the real-time corrosion rate of the internal components of the generator can be quantitatively calculated, and the future corrosion trend can be predicted. The application solves the problems that the traditional monitoring method cannot trace the source of hydrogen and cannot quantitatively evaluate the corrosion state, can effectively avoid the misjudgment of the unit state, provides a decision basis for realizing the preventive maintenance of the generator, and improves the operation safety.
