Three-phase PV inverters are generally used for off-grid industrial use or can be designed to produce utility frequency AC for connection to the electrical grid. This PLECS application example model demonstrates a three-phase, two-stage grid-connected solar inverter.
The grid-side converter transfers the power from the DC-link into the grid through an LCL filter, and maintains the DC-link voltage at 800 VDC. The control scheme for the grid-side inverter comprises a two-loop configuration with an outer loop for voltage control and an inner loop for current control.
The model represents a grid-connected rooftop solar PV system without an intermediate DC-DC converter. To parameterize the model, the example uses data from a solar panel manufacturer datasheet. Solar power is injected into the grid with unity power factor (UPF).
Figure 1: Inverter system. The power generation system is comprised of a solar array that provides a steady-state output of 700 VDC, a three-level inverter that has improved waveform quality as compared to a two-level inverter, and an LCL output filter connected to a low voltage 230 Vrms, 50 Hz grid system.
