Abstract:
The synchronous machine is widely used machine in industrial power plants. It has both field and stator control. The three-phase synchronous machine is widely used but main drawback of that is the size of the machine and control complexity when the rating of the machine is increased. The speed control of the synchronous machine is done by field control, vector control and direct torque control. In vector control the flux and speed are controlled and the required speed is achieved in many loading conditions. The problem in the vector control is it depends on the parameter of the machine. The machine parameter affects the performance of the speed control. So optimum parameter selection is must in this case. In DTC control vector is complicated in multi-winding machine. To control the switches pulse generation is complex. The vector control of multi-winding machine is better to control when the parameters are optimally set. And multi-level inverters are used to reduce the size of filters and to reduce the total harmonic distortion. To get better performance with multi-level the phase opposition or phase disposition is used as the pulse generator. The application of multi-machine system is on ships and aircraft like dedicated applications. From the analysis it is found that the optimal SPSG parameters can be selected by maximizing the efficiency of the machine by taking current limit, real and reactive power limits as constraints. Then the optimized six-phase machine is fed with
