One possible solution for coal mill capacity increase is analyzed and presented in the paper. It is based on application of MV variable speed drive with increased frequency of motor voltage supply in the range of 50-55Hz. In the paper the thorough
Low voltage (LV) variable frequency drives (VFDs) have been applied to applications up to 2500 horsepower (HP). Medium voltage (MV) VFDs have been applied to applications as low as 150 HP. Traditional power system design practice suggests that motor crossover from low voltage to medium voltage is in the 200-600HP range.
