To improve hydraulic turbine efficiency and preventing generation of noise and vibration by inhibiting vortex flow caused by a partition wall of a horizontal channel.
This generator set is provided with a vertical shaft valve type hydraulic turbine 11 having a hydraulic turbine shaft and a generator shaft arranged in vertical direction, a vertical channel in which the vertical shaft valve type hydraulic turbine 11 is arranged and water flows in vertical direction, a horizontal channel part 20 positioned at an upper part of the vertical channel, having the vertical channel connected thereto and making water flow to a part near a water introduction port in horizontal direction, and single or a plurality of partition walls 21 partitioning the horizontal channel part 20 in right and left. The partition wall 21 has arc shape parts 23a, 23b having diameters smaller than thickness of the partition wall at a tip part A and a tail part B thereof. Tip parts and rear parts of the arc shape parts 23a, 23b are formed in acute angles by straight lines or curved lines connecting with smoothly extending from a side wall surface of the partition wall 21.
