TO THE CALCULATION OF ENERGY INDICATORS FREQUENCY-CONTROLLED ASYNCHRONOUS ELECTRIC DRIVE IN STEADY MODE
Keywords:
energy saving, asynchronous electric drive, control law.Abstract
Electromechanical processes of a closed asynchronous electric drive, which characterize its energy parameters in the steady state, can be investigated without taking into account the modulation pulsations of the stator current. The calculation of the parameters of an asynchronous electric drive for the most common control law with constant rotor flux coupling is performed in a rotating coordinate system oriented along the rotor's flux linkage. Expressions were obtained for calculating the energy parameters of a frequency-controlled asynchronous electric drive in the steady state.
