Description
Summary:The paper describes FPGA-based real-time simulation method of photovoltaic systems. FPGA devices are widely used for power electronic systems control, but the same chip can have implemented real-time model of controlled system. Prototyping the control circuit before application in power system increases the safeness, and can reduce time and costs of implementation. FPGA-based prototyping of power systems enables research of the system sensitivity on parameters variations, or topology conceptions. The paper presents examples of designs of the FPGA-based models of PV array, PV grid-connected transformerless systems with single phase inverter and L and LCL filters, the dc/dc converter. The conception of FPGA-based realization of spectral analysis is also presented.
