Disturbance Investigation

A thorough post-event analysis helps to gain a clear picture of outages in power system operation and to define suitable mitigation measures.

    From the power system perspective, equipment faults and failures do occur frequently. Many fault and failure events do not even impact system operation – however, some events do cause undesired and sometimes incomprehensible impacts. Especially for multiple faults, the actual root causes, or even the observed events in system operation, are not easily understood. In these cases knowledge of different specialists has to be coordinated, e.g. on protection, insulation coordination, system dynamics, power system operation, equipment of different vendors. It is also necessary to consider post failure conditions, events and operational procedures and to cross check official statements.
