METHOD AND SYSTEM FOR HYDRO-TURBINES CONTROLLING Russian patent published in 2017 - IPC H02J3/38 H02P9/02 H02K7/18 H02M5/458 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in hydro-electric turbines. System of hydroelectric turbines array includes turbine systems array and control controller. Each of array turbine system comprises hydroelectric turbine and control system. Proposed system comprises: system of converter made with possibility to convert AC power supplied by generator, connected with hydro-electric turbine, and having voltage and frequency, which depend on hydro-electric turbine rotation speed, into AC power with voltage and frequency of transmission system for transmission of AC power to receiving substation; and control module made with possibility to interact with converter system for AC voltage control, supplied by generator. Master controller determines plurality of hydro-electric turbines within array efficiency level and instructs control module of at least one of turbine systems for AC voltage adjustment, supplied by generator for changing power generated by at least one of turbine systems, in order to control, thus, entire power generated by array.

EFFECT: technical result is separate turbines and group of turbines efficiency optimizing.
