Description

Изобретение относитс  к гидроэнергетике и может быть использовано в гидравлических турбинах.The invention relates to hydropower and can be used in hydraulic turbines.

Известны способы управлени  лопаст ми рабочего колеса гидротурбины, при которых установку угла лопастей оси производ т по суммарному нмпульсу от действующего напора и открыти  направл ющего аппарата. Св зь между открытием направ.л ющего аппарата, действующим напором и углом установки лопастей осуществл етс  при помощи кулачка комбинатора.Methods are known for controlling the blades of the turbine impeller, in which the angle of the axes of the blades is set by the total pulse from the operating head and the opening of the guide vane. The connection between the opening of the guide vane, the acting pressure and the angle of the blades is made with the help of a combinator cam.

Однако устройства дл  замера напора и дистанционного управлени  кулачком комбинатора сложны и неудобны.However, devices for measuring pressure and remote control of a combinator cam are complex and inconvenient.

Цель изобретени  - повышение точности и надежности управлени  лопаст ми.The purpose of the invention is to improve the accuracy and reliability of blades control.

Дл  этого угол лопастей устанавливают по суммарному импульсу от мощности гидроагрегата и открыти  направл ющего аппарата.For this, the angle of the blades is set by the total impulse from the power of the hydraulic unit and the opening of the guide vane.

На чертеже представлена блок-схема управлени  лопаст ми.The drawing shows a control block diagram of the blades.

Блок-схема включает направл ющий аппарат I, генератор 2, измеритель мощности 3, преобразователь 4, блок 5 золотников, сервомотор 6 рабочего колеса и лопасти 7 рабочего колеса.The block diagram includes a guide apparatus I, a generator 2, a power meter 3, a converter 4, a block of 5 spools, a servo motor 6 of the impeller, and a blade 7 of the impeller.

Управление по открытию направл ющего аппарата происходит с помощью передачи импульса от сервомотора направл ющего аппарата I к валу кулачка комбинатора, а управление по мощности - с помощью устройства, замер ющего мощность на шинах генератора 2 н преобразующего электрический сигнал в механическое перемещение кулачка комбинатора.The control of the opening of the guide vanes is carried out by transmitting a pulse from the servomotor of the guide vanes I to the shaft of the combinator cam, and the power control is controlled by a device measuring the power on the 2 n generator tires that converts the electrical signal into mechanical movement of the combinator cam.
