With the development of distributed generations, the related real-time simulation technology has drawn extensive attention. In the distributed generation units, the power electronics are critical parts. In order to better deal
with challenges of the large number of power electronic devices connected to the distribution network, this paper presents an embedded real-time simulation model based on associated discrete circuit (ADC) for a three-phase
voltage source inverter. This model can be implemented in a field-programmable gate array (FPGA). And the FPGA can reduce the computational burden of power electronics simulation, because of its powerful parallel computing
performance. First of all, a grid-connected power electronic inverter with a three phase RL filter model is built based on the ADC modeling approach, which can enhance the small step simulation performance. Secondly, the
phase-locked loop technology has been introduced into the system to track the information of the phase angle. Finally, a FPGA based voltage and current double loop control method is presented to ensure the stable operation.
The circuit simulation results verify the effectiveness of the scheme.
