FIELD: power industry.
SUBSTANCE: invention relates to the automatic control of hydroelectric power stations (HPPs) aggregates and is intended for use in the system for maintaining the regime of HPP aggregate with reactive turbine in accordance with the set upper level of control of the amount of electric power. The determination of guide vanes position setting is performed by integrating the mismatch between the power setting signal and the value of the nonlinear function equal to the turbine power value calculated from the factory or experimentally taken dependence on this servomotor position and the runner vane slewing position, determined by the combinatorial dependence under the assumption of the effect of net head on turbine; in the subsequent detection of discrepancy between the value of the power developed by the turbine and the value of this function and correction of used value of the head by adding to it the weighted sum of resulting error and the integral of it.
EFFECT: increasing the accuracy and speed of these systems, and in the case of using it in the control systems of rotary-blade turbines, it allows not only to simplify their adjustment and improve the quality of control, but also to increase the efficiency of turbines.
