Soft-input Power Supply Simulation Of Three-phase Induction Motor Under Different Conditions

In the three-phase load with important induction motor, ranging from its power to stop will soon put standby power to ensure sustained load operation, Also some of the load by way of realizing energy and power will produce very heavy input current of electrical equipment, will produce negative influence.In order to decrease the re-input electrical current, we need to study the control strategy of the induction motor when it was inputted in sync speed. We will establish a simulation model according to the mathematical equation of the introduction motor, then find the optimal strategy that minimizes the electrical current by controlling the trigger angle of thyristor and the input sequence of every power source.By combining the control strategy of the soft-input of the power source with the spasmodic power supply of oil-pump and observing what impact the time and rev will have on the power supply, we could have a chance to choose a proper time of cut-off the power and close-break.
