What is reversed power flow detection (RPR)?

Reversed Power Flow Detection Reversed Power Relay (RPR) are power directional relays, which are used to monitor the power flow and enact appropriate actions during abnormal conditions. Under an exceptional condition, the power direction changes from the Busbar to the generator. This situation usually occurs when the prime mover has failed.

What is a photovoltaic system with anti-backflow?

The photovoltaic system with anti-backflow is that the electricity generated by the photovoltaic is only used by the local load and cannot be sent to the grid. When the PV inverter converts the DC point generated by the PV modules into AC power, there will be DC components and harmonics, three-phase current imbalance, and output power uncertainty.
