Installation and operating experience of a 350HP AC drive for harmonic reduction

A variable frequency drive with sinusoidal line side power converter was applied to a new 350 hp induction motor driving a kiln at Mead Coated Board's Alabama paper mill in early 1994. The purpose of the installation was to replace an existing 250 hp motor and drive with a 350 hp unit. In addition with the GD4000 sinusoidal rectifier, the mill saw benefits in both line harmonic distortion and effects on system power factor. The results of this installation, including its effects on Mead's power system are described.<>
