Description
(54) СПОСОБ РЕГУЛИРОВАНИЯ ВОЗБУЖДЕНИЯ СИНХРОННОГО ДВИГАТЕЛЯ(54) METHOD OF REGULATING THE EXCITATION OF A SYNCHRONOUS MOTOR
гател , реализующа предлагаемый способ .gatel, which implements the proposed method.
Система содержит привод клети 1 осуществл емый синхронным двигателем 2, крут щий момент на валу двигател регистрируетс датчиком 3 момента, выходной сигнал которого дифференцируетс в устройстве 4, на выходе которого получаетс остроугольной импульс. Система содержит также регул тор 5 тока возбуждени и источник 6 питани .The system includes a drive of stand 1 carried out by a synchronous motor 2, the torque on the motor shaft is recorded by a moment sensor 3, the output signal of which is differentiated in device 4, the output of which is an acute-angular pulse. The system also contains an excitation current regulator 5 and a power supply 6.
Система работает следующим образом.The system works as follows.
В зависимости от величины амплитуды сигнала датчика 3 регул тор 5 тока возбуждени и источник 6 питани цепи возбуждени увеличивают ток возбуждени синхронного двигател 2. Пропорциональность тока возбуждени величине нагрузки обеспечиваетс пропорциональностью амплитуды сигнала производной крут щего момента величине крут щего момента на валу двигател . Максимум амплитуды продефференцированного сигнала достигаетс через врем ti после включени нагрузки, что меньше времени достижени максим.ума крут щим моментом примерно в 2 раза и меньще времени t срабатывани схемы регулировани по току статора. Интервал времени tjan. между моментом включени системы регулировани возбуждени в предлагаемом способе и моментом включени системы регулировани в известном способе регулировани по току статора не менее 0,3 с.Depending on the magnitude of the signal amplitude of sensor 3, the controller 5 of the excitation current and the power supply 6 of the excitation circuit increase the excitation current of the synchronous motor 2. The proportion of the excitation current to the load is provided by the proportion of the torque derivative signal amplitude to the motor shaft. The maximum amplitude of the differentiated signal is reached at a time ti after the load is turned on, which is about 2 times less than the maximum torque and less than the time t of the response of the stator current control circuit. The time interval is tjan. between the moment of activation of the excitation control system in the proposed method and the moment of activation of the control system in the known method of stator current control for at least 0.3 s.
Texникo- экoнoмичecкий эффект предлагаемого способа регулировани заключаетс в минимизации времени запаздывани . между приложением нагрузки и выработкой сигнала управлени , что повыщает эксплуатационную надежность работы двигател привода в целом.The textile-economic effect of the proposed control method is to minimize the delay time. between application of a load and generation of a control signal, which increases the operational reliability of the drive motor as a whole.
