Abstract

This paper presents investigation on multi criteria evaluation of induction motor energy saving strategy particularly applied in the small and medium scale industry. A walk-through motor energy audit is carried out in a typical type of enterprise to collect some important data. During the research, three induction motor energy saving strategies, by which energy efficient motor, variable speed drive, and capacitor bank are considered with respect to five criteria thought to influence the decision making in selecting suitable energy saving strategy for motor. With the support of economic as well as technical data required for each strategy, the multi criteria evaluation using analytic hierarchy process offers feasible solution corresponds to their inherent characteristic. It is revealed that capacitor bank is the most suitable saving strategy to the case of small and medium scale industry in this research and thus suggested to be provisioned at the first priority, followed by variable speed drive and energy efficient motor, consecutively.
