This paper deals with the problem of starting a large induction motor connected by a medium- or short-length transmission line to a comparatively small power system built mainly for oil pumping purposes. The associated problems of dynamic stability and bus transfer are discussed. It is shown that the recommended reduced-voltage techniques for starting induction motors may fail, but that it is possible to start the motor directly on-line. It is concluded that the system as a whole must be considered when designing the induction motor and specifying its starting procedure. Simulation results and field experiences are reported.
