ABSTRACT:
A hydroelectric system is disclosed which is designed to run intermittently to compensate for a low flow source. A float system is employed to control the operating points of the turbine by opening an inlet valve at one predetermined pond level and closing the inlet valve at a lower predetermined level. A novel entrance to the turbine inlet pipe is also disclosed which eliminates problem turbulence when the pond level is near the lower predetermined limit.
