The mechanical vibration of the model runner for power storage happens during the hydraulic performance test at high and variable speed due to its large mass and eccentricity.The vibration not only affects the hydraulic performance test indexes,but also leads to a series of serious consequences.The dynamic balancing technology is of great significance to alle-viate the mechanical vibration.This paper introduces the relevant knowledge of dynamic balancing technology,and proposes feasible engineering measures for addressing the imbalance issue of the model runner through static balancing tests,dynamic balancing tests,and corresponding calibration procedures.
