Abstract:
Disclosed are a method and device for processing a voltage drop, a grid interconnection method and device for processing an electrical apparatus, and a system. The method includes: acquiring a drop amplitude of a voltage for each phase in a three-phase alternating current (S 204 ); and under a condition in which a voltage for any phase in the three-phase alternating current drops, performing reactive power compensation according to a drop amplitude of a voltage for a phase in which the voltage drops (S 206 ). Therefore, the electrical apparatus has a low voltage ride-through function, thereby solving the technical problem of a large deviation of voltage drop amplitude determination arising from an asymmetrical drop of three phases.

Claim (Index 6):
The method as claimed in  claim 5 , wherein controlling grid interconnection of an electrical apparatus according to the voltage angle comprises:\n under a condition in which a voltage of the power grid does not drop to a threshold value, acquiring the voltage angle, controlling the grid interconnection of the electrical apparatus according to the voltage angle, and storing the voltage angle; and under a condition in which the voltage of the power grid drops to be below the threshold value, controlling the grid interconnection of the electrical apparatus according to a voltage angle stored in a previous time.
