Cost Effectiveness of 'NOLA' Controlled Motors, Including Effect of Higher Harmonics.

Abstract

An economic analysis of the NOLA Power Factor Motor Controller is accomplished and the effects of the harmonics produced by the controller are studied. The controller is placed in series with each leg of various sizes of wye-connected three-phase motors. The energy saved by the controller, the power factor correction, and the reflected harmonics under varying load conditions are studied to determine the economic advantages. Also the data from the controlled motor is compared to an energy efficient motor. An analog-digital computer program is developed which models an induction motor and the NOLA controller. The computer model is used to determine and analyze the reflected wave shape produced by the controller. The results of the study indicates that the energy efficient motor is the most effective alternative at the present time because of the high initial cost of the NOLA controller. Continued studies are recommended to determine the effects of the higher harmonics. (Author)
