英文摘要	To obtain the hydro-dynamic torque magnitude and its variation law of the pump turbine under the turbine mode, the electromotive stress analysis method and the specially processed shaft of guide vane were applied in a pump turbine model of the domestic pump storage plant. The hydro-dynamic torque of each guide vane was investigated under the situation of synchronous guide vane and misaligned configuration respectively. The main conclusions are as follows: once the synchronized guide vane is employed, with the opening increasing, the hydro-dynamic torque factors magnitude of the guide vane has the consistency among all tested vanes, and the direction of the torque shift gradually from the turn-off direction to the turn-on direction. When the 10# guide vane is set as the misaligned guide vane, and the difference between misaligned guide vane opening and the synchronous one is less than 16.4%, the hydro-dynamic torque factors of the tested guide vanes tend to be distributed regularly. However, when the opening difference is bigger than 16.4%, the hydro-dynamic torque increases sharply with the use of the misaligned guide vane, and the hydro-dynamic torque factors of the different guide vanes change significant. © 2018, China Water Power Press.
