INTELLIGENT AUTOMATIC SYSTEM FOR CONTINUOUS OPTIMAL ADAPTATION OF HYDROKINETIC ENERGY CONVERTERS TO THE DEPTH AND SPEED OF WATER FLOW

Resumen de: BG113918A

It is used to increase electricity generation from various primary hydrokinetic energy converters by maintaining their optimal position in the water flow. Its main advantage is that it autonomously ensures optimal operation under the control of artificial intelligence. The intelligent system includes a platform (1), a rotating shaft (2) with blades (3) fixed to it, connected to a power transmission (4), movably connected to a platform electric generator (5). It is characterized by the fact that linear inclined toothed rails (6) are fixedly mounted on the platform (1), and the rotating shaft (2) is supported on a rail gear mechanism (7) with a controllable electric valve (8), whose control input is connected by cable, through an executive device (9), to a power control output from an optimizing electrical control unit-regulator (10), whose first signal input is connected to a signal output from a flow depth sensor (11), a second signal input is connected to a signal output from a combined sensor for temperature and speed of natural water flow at its depth (12), a third signal input is connected to a signal output from a sensor for the electrical parameters of the platform's electric generator (13), whose cable output, via an electrical converter (14), is connected by cable to electrical consumers.
