Abstract

PURPOSE:To wash off a foreign material, which is clogging a guide vane, by controlling the captioned water turbine in such a manner that the guide vane on the clogged side is freed, when the operating force of the guide vane becomes too large, which is caused by the foreign material that was caught in the vane during the closing operation. CONSTITUTION:If a foreign material is caught in a guide vane during the high- efficiency operation, it becomes impossible to close the vane, and the operating force to a guide vane operating unit becomes too large. At this time, this excessive operating force is detected, and this situation is indicated. When the detection time or the detection count on this excessive operating force is below the predetermined value, 'foreign- meaterial-clogged-operation' is conducted. At this time, of the guide vanes 1a and 1b, the guide vane, which can no longer be closed and which results in excessive operating force, is full opened. With this operation, it occurs frequently that the foreign material that was caught in the guide vane is washed away. When the predetermined time elapses after the 'foreign-material-clogged-operation', the guide vane, which is clogged with a foreign material and which is full opened, is closed. When the clogging, foreign material cannot be washed away even after the 'foreign-material-clogging- operation', the 'foreign-material-clogging-operation' is repeated.
