FIELD: control systems.
SUBSTANCE: group of inventions relates to control of hydraulic turbine control system of hydraulic turbines. In the method of control of hydraulic turbines control, which consists in execution of the specified position of the main servomotor using signals of position sensors of the main slide valve and the main servomotor and based on comparisons of the positions of the main slide valve and the main servomotor specified and measured by the sensors, the servo position sensor of the main servomotor is tracked. In case sensor fault is detected, setting signal is generated for hydraulic control valve by means of frequency and power control circuits corresponding to preset position of main slide valve. Setting signal is adjusted taking into account the signal received from the sensor. Adjusting the setting signal using main spool loop gain, so that hydraulic power system control until measurement of sensor is restored.
EFFECT: group of inventions is aimed at higher efficiency and efficiency of hydroelectric unit, which includes hydraulic turbines regulating devices hydraulic amplifiers system, as well as to increase its service life.
