The aim of this investigation was to improve power performance of Savonius hydraulic turbine utilizing small stream for electric generation. An attempt was made to increase the power coefficient of runner by use of a flat shield plate placed upstream of the runner. The difference of the power coefficient is discussed in relation to a rotation direction of the runner and with/without the shield plate. The flow field around the runner was also examined visually to clarify influences of installation conditions on the power performance. From this study it was found that the power performance of the Savonius runner is drastically changed by the use of shield plate and with the rotation direction, and then the maximum power coefficient of runner is achieved for 47 %.
