6 FAQs about [Solar power station meter reverse phase sequence]

How does reverse power flow affect Protection coordination scheme?

The reverse power flow occurs when the production of DG exceeds local load demand or when local demand reduces so that power flows in the opposite direction and causes abnormal performance of the protection system. In this section, the effect of reverse power flow on the protection coordination scheme is analysed.

What happens if a PV plant does not have a net meter?

In simple words, power will flow from the PV plant owner’s home to the connected grid [when Solar power generation > Power required by connected load]. And if the net-meter is not installed at the PV plant owner’s home. This excess power will increase the electricity bill of the PV plant owner.

Does phase reversal/polarity affect source/load?

Everything below is related to calculations and measurements of that Measuring device. Phase reversal/polarity does not have an effect on source /Load, only the Meter measurements will be affected. I know about the phase sequence and Power equations of a 3-Phase Balanced System.

What is the function of grid side converter in solar PV?

The output of solar PV, V is directly converted to V. Here, grid side converter performs various functions, such as MPPT, voltage regulation control at dc link, grid current, and voltage amplification. The single-stage inverter carries double peak power represented as: (1) Where, represents grid power and represents frequency of grid.

How does relay protection affect reverse power flow and short-circuit level?

In a possible scenario of a fault in the line connected to the DG, the relay protection of the generator can view the fault, make the trip for and isolate the generator of the system. This work analyses the impact of RE on reverse power flow and short-circuit level.

How does ARPC calculate reverse power?

ARPC will detect grid voltage on R,Y,B input and current on CT, the CT are connected before the local load input. The ARPC can calculate the reverse power by voltage and current. In case local load power is less than solar inverter power, then there will be reverse power detected on ARPC.
