Aggregating Method of Induction Motor Group Using Energy Conservation Law

Pichai Aree

Abstract


This paper proposes a simple and efficient method for aggregating a group of induction motors, which are connected at the same bus. The parameters of aggregate motor are derived using a technique based on energy conservation law. An accuracy of the aggregate model parameters is veried by comparing dynamic responses obtained from the aggregate motor with the sum of individual motors. The presented technique gives accurate parameters in which the dynamic responses from the aggregate motor closely reflect the behaviour of a whole group of the motors under study.
