When Variable Frequency Drives (VFD's) are installed on a power system, serious harmonic problems can result. Voluntary harmonic standards, such as IEEE Std 519, and mandatory harmonic standards, such as those recently introduced by Marine regulating bodies, identify design limits but how do you know if your designs or applications meet these limits?

Mirus International Inc. has developed a powerful yet easy to use computer simulation program that can be configured to model your VFD application. Unlike some other harmonic estimating tools which use look-up tables, SOLV (Simulation of Lineator/VFD) models the load and power system equipment and resolves the differential equations to achieve much more accurate results. Several reports are generated including an IEEE Std 519 compliance report, a one line diagram, waveforms, spectrums and harmonic distortion levels.

Simulations can be done with many load variations including, (i) standard VFD's with or without reactors, (ii) multipulse VFD's and (iii) VFD's with Mirus' Lineator Advanced Universal Harmonic Filter (AUHF).
