6 FAQs about [Huawei photovoltaic inverter reactive power regulation]

How does a photovoltaic inverter work?

Power generation flowing through the transmission line causes unintended flow of reactive power to the grid side, as the transmission reactance consumes reactive power. Thus, the grid-side reactive power becomes coupled with the active power production of the photovoltaic inverter, which fluctuates along with irradiance conditions.

Can a PV inverter control reactive power during autonomous operation?

Manual reactive power control during autonomous operation Most of the new PV inverters are capable of reactive power support. The proposed autonomous compensation method defaults the grid-side reactive power to zero, but does not interfere with external reactive power control.

What is power factor fix control in a solar inverter?

If the PV plant is required to generate a constant power factor at the grid-tied point and the solar inverter is required to adjust the real-time reactive power based on the preset power factor, set this parameter to Power factor fix control.

What happens if a PV inverter has a weak grid?

Thus, in a weak grid the active power of a PV inverter becomes coupled with reactive power seen by the grid. Unintended reactive power increases transmission losses, reduces the maximum transmission capacity, compromises system stability, and strains the grid with excessive reactive power requirements , , , , .

How to control reactive power in a current-controlled inverter?

A widely applied method for reactive power control in current-controlled inverters is power factor control (PFC), where the cos ϕ of the inverter is set to other than unity. PFC provides flexible method to regulate the reactive power output of the converter by associating reactive power input to active power level.

How does a PV inverter operate at unity power factor (PF)?

The active power from an inverter operating at unity power factor (PF) appears as both active and reactive power on the grid side. Thus, in a weak grid the active power of a PV inverter becomes coupled with reactive power seen by the grid.
