Abstract

This paper analyses via simulations and theoretical demonstration, the possibility of zero-missing phenomenon after clearing a fault at a substation or its vicinity. The paper demonstrates how the phenomenon may occur and that the initial DC current of the shunt reactors may be larger than the shunt reactor peak AC current. As a result, zero-missing after fault clearing might be more severe than during the energisation of the cable in the same system. The impact of different system parameters is studied and the worst-case scenario defined. Typical countermeasures are ineffective for this case and a possible new countermeasure is introduced.
