Abstract: A stepwise operating parallel-type hydro power generation system having a fixed flow path includes a parallel pipe, a first power generation facility, a second power facility generation facility, first and second flow regulators, and a controller. The parallel pipe includes an inlet pipe, an outlet pipe, and a first straight pipe and a second straight pipe. The first and second straight pipes connected between the inlet pipe and the outlet pipe. Each of the first and second power generation facilities includes a water turbine rotating with the water introduced thereinto and a power generator operating according to the rotation of the water turbine. The controller is configured to open and close either or both of the first and second flow rate regulators at the same time.
