QUALITY CONTROL OF ENERGY CONVERSION IN ALTERNATING CURRENT DRIVE: PROBLEMS AND WAYS TO SOLVE IT

Proved a problem quality control in electric energy conversion with electric AC motors, which are powered from the mains with an asymmetric and nonsinusoidal voltage, have acquired parametric asymmetry. Presented research on the application of quality management principles developed energy conversion. The possibility to compensate for the high-er harmonics of the power consumption and electromagnetic torque of electric motor by controlling the power converter in the stator and rotor circuits. The proposed principles extended to systems with thyristor voltage regulators on the stator frequency converters and inverters with independent PWM output voltage drives with asynchronous motors with thyristor excitation system of synchronous motors, as well as search optimization system.
