Power System Fault Data and Time Series

Each interruption can be interpreted as time series with a several parts: preparing time (for repairing), fault location time, repairing time, fault duration time (for radial power lines) and non voltage time (for redundant city power lines). Preparing time is duration between start fault moment (start whatever by SCADA or by consumer phone call) and ready moment (maintenance-repair team is on the power line area). Now, it is possible to compare function modes, different maintenance and investments policy. All given information provide reasonable guidelines in system function and system state prediction in future periods, decreasing system function difficulties and solving problems in some kind of iterating process based on comparing with alternative power system. Power system reliability indices are good comparing base for power system function during the time period. Importance is exactly in possibility to mark and improve power system at any time.
