SOFT START-UP OF HIGH-VOLTAGE AC MOTOR OF GENERATOR UNIT FORMATING THROUGH BY THE USE OF LOW-VOLTAGE CURRENT SUPPLY
Abstract:
The analysis of features of drive systems energy-cyclical mechanisms electromagnetic compatibility and long cable power lines has performed. It was found that for such operating conditions it is advisable to use in the main drives a multi-machine converter units with system of generator - motor. The starting problem of the multi-machine unit at direct connection of high-voltage AC motor under mains voltage is revealed, that is consists in generate significant starting currents and "failures" of the voltage in the mains. A method for starting a powerful network motor in the generator-motor system by incorporating a low-voltage inductive-capacitive converter, over the starting period has been included in the anchor chain of the generator. The analysis of current changes in an inductive-capacitive transducer at the time of start-up drive of the generator is fulfilled. The laws of overflow capacity has defined. A values of the resonance voltage are analyzed.
