| Abstract |
A new method for simulating converter-induction machine associations has been applied as an alternative to the conventional 2-axis machine approach. This method uses an equivalent circuit approach, and yet models the machine characteristics directly in terms of stator (voltages and currents) and mechanical system (torque and velocity) variables. The main advantages are the ease of describing the system by a general set of equations using the efficient nodal method, the flexibility of implementation to other converters and investigation of the system in normal and fault operation. The structure of the machine model allows for its application in general purpose simulation software. The approach is demonstrated using a 3-phase induction machine supplied by a PWM inverter, represented by a varying PWM voltage source as well as a current inverter given by its actual topology. Several examples illustrate the main features of the approach. |
