Energy Audit And Management Of Induction Motor Using Field Test And Genetic Algorithm

This paper proposes an economical method that can be used by industries/plants to make a right decision in replacing the inefficient induction motors with efficient ones. proposed method focuses on the field efficiency of motors without the needs for removing motors and measuring the output power. The use of a few sets of measured data from field test coupled with the genetic algorithms using one operating point for evaluating motor equivalent circuit parameters instead of using the no load and blocked-rotor tests is proposed. Test results indicate that this method has a high accuracy, then it is suitable for conducting onsite energy audit of motors in order to project cost savings and payback and to support a confidence decision regarding the investment in higher efficiency motors.
