Zusammenfassung:	PURPOSE:To automatically level operation time of respective nozzle groups of a Pelton turbine having a plurality of nozzles. CONSTITUTION:This device is comprised of operation signal units 1-3, an operation time integrating unit 6, a nozzle group selecting unit 7 to select a nozzle group to be operated or stopped corresponding to the output of a Pelton turbine, and nozzle operation commanding units 8-10, and for leveling of operating time by the use of the nozzle group selecting unit 7, the command of operation is transmitted to a nozzle group to operate the nozzle group, or the command of operation is stopped to stop the nozzle group, and hence operating time of the nozzle groups can be levelled.
