FIELD: hydropower.
SUBSTANCE: invention can be used to control combinatorial dependencies when conducting tests on a working hydraulic unit. Automated method of identifying the coordinates of the combinatorial mode point on the power isoline of a given value, on the "position of the guiding engine of the servomotor / position impeller of the servomotor" plane was developed, which is characterized by unequivocal results and can be performed without turning off the hydraulic unit or employing special measuring devices.
EFFECT: invention is aimed at improving the reliability of determining the coordinates of the point of the combinatorial mode during normal operation of the hydraulic unit.
