FAQs 6

What is the output voltage of a PV inverter?

It is seen that the inverter is operating smoothly during the normal operating condition and the output voltage of 796.4 V power of 1504 kW (approximate) from PV power plant as well as grid parameters, i.e. grid voltage of 33 kV and grid power of 1 MW are also maintaining normally.

What is grid interfacing & inverter control?

Grid interfacing and inverter control are two major aspects for grid-connected PV system. Generally, inverter and grid are interfaced via a phase-locked loop which is operated in relatively low bandwidth but such practice causes delay to detect the fault.

What is a control strategy based on instantaneous power theory?

The control strategy, based on instantaneous power theory, can directly calculate the active and reactive component of currents using measured grid voltage and currents and generate inverter switching pulses based on the formulated reference current values and thus helping to improve the dynamic response when voltage sag takes place.

Can photovoltaic inverters be regulated under imbalanced voltages?

The simulation results efficiently validate the suggested computation approach that is presented in the current reference. Recently, the regulation of photovoltaic inverters, effectively under imbalanced voltages on the grid, has been crucial for the operation of grid-connected solar systems.

How can a large-scale PV plant be used to generate electricity?

Among all, solar photovoltaic (PV) and wind turbines have currently become the strongest pillar for electric power generation as a replacement of conventional methods. Thus, interconnection between large-scale PV plants and electric power grid via voltage source inverters has been widely employed to meet the load power demand.

What happens if a PV inverter fails?

The voltage at point of common coupling (PCC) drops during the fault, the inverter must be switched into LVRT operation immediately. As the consequence of fault, the imbalanced power of both PV and grid causes transient in dc side voltage and ac side current.
