Abstract

Изобретение относится к области энергетики и может быть использовано в электрогидравлических системах регулирования паровых турбин с применением средств микропроцессорной техники. Предложен способ регулирования положения отсечного золотника, управляющего перемещением сервомотора, в свою очередь управляющего клапанами паровой турбины в системе регулирования паровой турбины, с динамической коррекцией смещения "нуля" отсечного золотника, включающий определение требуемой величины перемещения отсечного золотника для достижения заданного положения сервомотора и перемещение отсечного золотника в соответствии с ранее определенным значением, отличающийся тем, что на этапе определения величины перемещения отсечного золотника до начала регулирования измеряют значения смещения "нуля" отсечного золотника в различных положениях штока сервомотора во всем диапазоне перемещения этого штока; а при регулировании производят расчет величины динамической коррекции смещения нуля для заданного положения штока сервомотора с учетом смещения "нуля", измеренного для текущего положения штока сервомотора, и учитывают динамическую коррекцию нуля при определении величины перемещения отсечного золотника. Техническим результатом является повышение точности позиционирования регулирующих клапанов вследствие минимизации пульсаций сервомотора в установившемся режиме путем коррекции положения "нуля" отсечного золотника при изменении текущих условий работы системы регулирования.The invention relates to the field of energy and can be used in electro-hydraulic systems for regulating steam turbines using microprocessor technology. A method for regulating the position of the shut-off spool controlling the movement of the servo motor, in turn controlling the steam turbine valves in the steam turbine control system, with a dynamic offset offset of the shut-off spool, including determining the required amount of movement of the shut-off spool to achieve the specified position of the servomotor and moving the shut-off spool in accordance with the previously determined value, characterized in that at the stage of determining the magnitude of the movement of the cut-off prior to the start of regulation, the offset values of the “zero” cut-off spool are measured at various positions of the servomotor rod over the entire range of movement of this rod; and when adjusting, they calculate the value of the dynamic zero offset correction for a given position of the servo rod, taking into account the zero offset, measured for the current position of the servo rod, and take into account the dynamic zero correction when determining the amount of movement of the gate valve. The technical result is to improve the positioning accuracy of control valves due to minimizing the servo motor ripple in the steady state by adjusting the zero position of the gate valve when the current operating conditions of the control system change.
