Influence of the Arc Suppression Coil with Parallel Resistance on Single-Phase Arc Grounding Overvoltage

Abstract:

Neutral point grounding method with an arc suppression coil and a parallel resistance is a method that can inhibit arc overvoltage effectively. Through the simulation of arc suppression coil with parallel resistance in the situation of different resistance value, we can obtain if the parallel resistance is too big, it will produce overvoltage in the later of voltage recovery; if the parallel resistance is too small, it is easy to produce larger grounding residual flow, going against quenching of arc; Whether over compensation or owe compensation, oversized out-of-resonance degree will cause the fault phase voltage recovery oscillation overvoltage, small out-of-resonance degree is beneficial to the fault phase voltage rise slowly.
