Simulate the starting characteristics of the induction machines, whose parameters are as follows, by using digital computer. At t = 0 s, a-phase voltage is crossing zero with a positive slope. The balanced three-phase voltage with the rated voltage and rated frequency of each induction machine is applied to the machine. The load torque and the inertia of load can be neglected. For each machine, plot a-phase voltage (V), a-phase current (A), torque of the machine (N-m), and speed (r/min) in the vertical axis simultaneously until the starting of the machine finished and the machine is in the steady state. Here, the steady state means less than 3% variation of the magnitude of the current between consecutive cycles. In the plot, horizontal axis is time from zero until the end of the starting. Also, for a starting interval, the plot torque-speed curve in the torque-speed plane, where the vertical axis is torque (N-m) and the horizontal axis is speed (r/min) [7].
