Starting of diesel electrical aggregate loaded with an induction motor

Switching larger induction motors on the buses of a diesel electrical aggregate causes large voltage and frequency drops. Also, it can cause severe disturbances to any locally connected loads on the aggregate's buses. In this paper, a method of starting an induction motor, loaded on the aggrega...

Description
Summary:Switching larger induction motors on the buses of a diesel electrical aggregate causes large voltage and frequency drops. Also, it can cause severe disturbances to any locally connected loads on the aggregate's buses. In this paper, a method of starting an induction motor, loaded on the aggregate, by simultaneously changing voltage and frequency is presented. Besides the mathematical model of the diesel electrical aggregate, a mathematical model of the induction motor is also given. Results obtained with simulation are compared with experimental results obtained from a laboratory model. With this method, the starting of larger induction motors can be realized without using special starters (soft start).
