Zusammenfassung:	PURPOSE:To suppress the occurrence of a water hammer of a conduit system by disconnecting a generator from a power system by the rotation stop signal of a volume type turbine, and operating a flow rate regulating valve. CONSTITUTION:Fluid is fed by the operation of a pump 4, and a generator 6 is operated to generate by the energy of the fluid while regulating the flow rate in a volume type turbine 5. If a foreign matter, etc. is introduced between the rotary unit and the stationary unit of the turbine 5 during an operation to stop rotating, a rotation stop signal is transmitted by a rotating speed detector 8 to a controller 12 of a conduit system. When the controller 12 receives the stop signal, it interrupts a breaker 7 for connecting an external power system and opens a flow rate regulating valve 11 provided in a bypass conduit 9.
