AI Technical Summary
Technical Problem
Existing technologies struggle to accurately assess the health status of hydropower units under non-normal distribution conditions, and conventional methods are ineffective.
Method used
Independent component analysis (ICA) and independent filter correlation (IFC) techniques were used to decompose the hydropower unit operation data to obtain health values and characteristic values, which were then used to evaluate the health sample characteristic values.
Benefits of technology
This technology separates data representing the health status of hydropower units from data on other affected states, thereby improving the accuracy of health status assessment.

Abstract
This application discloses a method, apparatus, device, and storage medium for assessing the health status of a hydropower unit. The method includes: acquiring current operating data of the hydropower unit; performing Independent Component Analysis (ICA) on the current operating data to obtain the current health value and current Independent Filter Correlation (IFC) characteristic value of the hydropower unit; obtaining health sample characteristic values and IFC state characteristic values of the hydropower unit; and assessing the health status of the hydropower unit based on the current health value, current IFC characteristic value, health sample characteristic value, and IFC state characteristic value. This technical solution achieves the separation of data representing the health status from other affected status data in the hydropower unit's operating data, enabling a more accurate assessment of the hydropower unit's health status.
