| Summary: | More and more attention has been paid to the energy crisis due to the increasing energy
demand from industrial and commercial applications. The utilization of renewable
energy considered as one of the most promising electrical energy sources, which has
grown rapidly in the last three decades. In this day and age, many power converter
techniques have been developed to integrate renewable energy with the electrical grid. In
this work, there is a new technical control is known as synchronverter control which is
using the synchronous generator mathematical equations as a reference. This
synchronverter control is connected with DC-AC three phase inverter to work as
controller of output power to feed the load. In this control strategy, the output current of
the controllable inverter is controlled by a feedback load current according to the current
reference. The synchronverter technology has been applied to control the inverter for the
induction motor connection. An experimental setup based on DSP (Digital Signal
Processing) and dc drive board have been designed to implement the open and closed
loop experiments. All experiments have been implemented on a test rig based on Matlab
20013a/simulink software and Code Composer Studio V6.0 to demonstrate the excellent
performance of the proposed control strategies with stability of the system, sinusoidal
currents and good dynamics. Finally, an improve control strategy based on the
synchronverter control technology has been tested for three phase inverter for renewable
energy applications to make the whole system behave as a synchronous generator. |
