Abstract:This project examines transient induction motor machine torque during fast bus transfers. In an effort to limit the damage to motors during a transfer, industry standards specify that the resultant vectorial volts per hertz between the motor and voltage source must not exceed 1.33 per unit. This project studies the correlation between induction motor electromagnetic torque and the industry reclosing limit for multi-motor systems. A dynamic induction motor model is presented and a three-motor bus that is typical of nuclear power stations is modeled for the simulation of the fast bus transfer. A signal processing approach to determining the instantaneous volts per hertz phasor of the multi-motor bus is presented. Simulations of fast bus transfers of varying length are performed and the results are discussed.
