Adjustable speed drive (ASD) ride-through issues have caused increased concerns due to the susceptibility of drives to power disturbances and the costly results of process disruptions. This study assesses ride-through alternatives for medium voltage applications for several common manufacturers` topologies. This report will help industries and the utilities serving them determine appropriate medium voltage ride-through approaches to serve their applications. The application of medium voltage drives is increasing due to increased reliability, energy efficiency, and improved process control. However, medium voltage drives are susceptible to voltage disturbances such as sags, swells, transients, and momentary outages. According to survey reports, voltage sags of 10--30% below nominal for 3 to 30 cycles account for the majority of power system disturbances. Medium voltage drives tend to experience ride-through problems during voltage sags below 85% of rated voltage for more than one cycle. Depending on the application and the characteristics of the disturbance, the drive-controlled process may be momentarily interrupted or permanently tripped out. Either outcome can result in a significant loss in revenue and costly down time.
