Title: Output control for hydraulic power plant
Inventor: YOKOTA HIROSHI
IPC: F03B15/14
Filed: 1981-10-30
Abstract: PURPOSE:To utilize an output control in a hydraulic power plant efficiently for an electric system in response to variation of frequency by carrying out water level adjusting running or governor-free one corresponding to system frequency. CONSTITUTION:When system frequency is within a predetermined deviation with respect to the reference frequency, water level adjusting running is carried out by a load limiting motor. When it exceeds this frequency band, a follow-up circuit is excluded to carry out governor-free running and operatively restrain the variation of system frequency. And when the system frequency returns within this range again, running is returned slowly to water level adjusting one by a timer to eliminate shock due to change-over of mode. In this case, the load limiting motor is shifted to the water level adjusting signal so that the output of a speed setter is adapted to follow up slight above the load limiting position in the same manner as the previous condition.
