Title: Control method for pelton wheel
Inventor: HAYAKAWA KEIZO
IPC: F03B15/22
Filed: 1984-09-29
Abstract: PURPOSE:To eliminate construction of a wasteway and to enable reduction of a construction cost, by a method wherein waste water, injected through an injection pipe not used for generating running, is turned away with the aid of a deflector and is discharged without being exerted on a bucket wheel, and a water level in a water tank is regulated. CONSTITUTION:When control is started, a necessary water quantity Q, flown down through a penstock, is read from a memory device. Meanwhile, an opening Si of a needle 14 of an injection pipe 11, used for generating operation, is detected by a detector, not shown. Based on the detecting result, a water quantity Q1 used for power generation is calculated, waste water quantity Q filtration =Q-Q1 is calculated, and based on a characteristics curve, not shown, an opening S filtration of the needle 14 is calculated. A discharge injection pipe is selected from the injection pipes 11, not used for power generation, and the needle 14 thereof is opened to discharge water water. In which case, a deflector 16 is fully closed to prevent jet water from being exerted on a bucket wheel 12. This eliminates construction of an expensive wasteway, and enables a water level in a water tank 3 to be regulated in a given range.
