Abstract

PURPOSE: To prevent a water-wheel generator from overload and cavitaton phenomena, by an operation of limiting a permissible load for the water-wheel generator in accordance with a change of static head and number of sets of the operating generator.
CONSTITUTION: A load setting set value V1 is inputted to an upper and lower limit limiter 12 becoming a load integrated cmmand value V2, and a difference V2a, between the load integrated command value V2 and an output V4a-1 to V4a-n of each generator, is inputted to a command value distributor 13 as a load command value. The command value distributor 13 will distribute the load command value V2a to load command values V3-1 to V3-n of each generator. An upper limit value generator 17 and lower limit value generator 18, with a water-level difference V7 between top and bottom dam and number of sets of the operating generator imputted, will output an output upper limit value V8 and output lower limit value V9 to the upper and lower limit limiter 12
