Experimental study of Micro sources inverter based on virtual synchronous generator

The virtual synchronous generator (VSG) inverter implemented based on real-time workshop (RTW) is proposed. The design cycle of VSG implemented based on RTW is shown. Consulting the traditional mathematical model of synchronous generator in power system, the virtual synchronous generator model is built in MATLAB/Simulink, and realizing the model conversion to the code automatic. Then the Micro-source inverter platform is built. Comparison with the droop control strategy by experiments, it is proved that the control strategy of virtual synchronous generator is superior. The method based on RTW can reduce the time of compilation, integration and debugging, the efficiency is improved greatly on research. Finally, the method of measuring inertia and the formula are given.
