Energy efficient design of three phase induction motor by water cycle algorithm

Abstract The demand for electricity is growing very fast; as a result, the entire power sector is facing a real problem of meeting the additional demand. Rigorous energy audit suggests the replacement of energy-efficient devices from standard one, operating with poor efficiency and consumes large power. 3-phase induction motor is widely used as driving power in most of the industries and it consumes almost 65% of the total power. The energy-efficient design of such motors saves a considerable amount of energy and reduces the cost of operation. In this paper, an attempt has been made to design energy-efficient induction motor from different perspective of using design and optimization without high-quality material. In this paper, the cost of yearly energy losses is considered as objective function and it is optimized to save energy and money as well. The design problem is a nonlinear constraint optimization problem, which involves many variables and constraints. Water Cycle Algorithm (WCA) is one of the most recently developed metaheuristic algorithm is taken for the optimization for the case study of 5 HP and 10 HP, 3- phase, Squirrel cage induction motor. The objective function is optimized by WCA and Genetic Algorithm and their result is compared for accuracy from cost and performance point of view. WCA found to be the most efficient tool to optimize the problem and helps to design an energy-efficient motor.
