Abstract
The issues of reliability and operation safety of power equipment, including hydraulic units of hydropower plants, are becoming more and more relevant with the increasing the service life. The long operation period and the individual characteristics of hydraulic units do not allow to apply outside the design lifetime the methodology for assessing the technical condition based only a simple extrapolation of the results of previous surveys. The integrated approach that combines application of modern diagnostic systems capabilities and achievements of computing technologies, the generalization of theoretical experience and the results of numerous experimental investigations using model and full-scale hydraulic units makes it possible to reliably and reasonably predict changes in the technical condition of hydraulic units, not allowing to reduce the reliability and safety below acceptable level. The material of this article was partially presented at the round table "Siberia Hydropower Development" at the VII Siberian energetic forum in 2016.
