      In this technique, the switching patterns for the bridge inverter are generated from the knowledge of stator voltage space phasor. A reference voltage vector is generated to generate a field synchronous with the rotating voltage vector by utilizing the different switching states of a three phase bridge inverter as shown if figure4 and table 2 ...

      The entire system is simulated on the MATLAB-SIMULINK platform. `Fig 1 shows instantaneous stator voltage and stator current in steady state. Its frequency, magnitude and phase is independent from the rotor speed. In grid connected stator flux is maintained constant by grid. In stand alone mode, stator flux is keep constant by RSC.

      In solving this problem it will be more convenient to represent the decision variables in terms of the phasor angles, I, since these angles directly control real power flows. In addition to this, the power flow constraint must always be satisfied in the network. ... A simulink block diagram for the PLL frequency estimator is shown in figure 27.
