Abstract

Over-voltage at the motor side when supplied by Voltage Source Inverter (VSI) using long cables could cause winding failure and it is known to be source of electromagnetic disturbances, both radiated and conducted. In this paper, the over-voltage prediction for such drives in industrial environment has been investigated. Minor run time execution and precise simulations are the main paper targets. A novel cable model has been considered for motor over-voltage and converter overcurrent estimation. Two different measurement methodologies for the model parameters have been introduced too. The first methodology is accurate and could measure both the proposed parameters needed by the application and the filter parameters needed to mitigate these problems. The second is simpler and could only estimate the filters parameters. Comparison between experimental and simulation results are presented in the paper to confirm the proposed methods.
