Abstract-Failure events in substations often result in multiple outages of generators, lines andlor loads in power systems. The simulation of substation originated outages for practical substation configurations is difficult, due to the complex switching actions with disconnect switches and circuit breakers that can take place. A digital computer program has been developed at the Delft University of Technology, which simulates these complex switching actions following substation failures. The simulation algorithms, which deduce the contingencies before and after switching actions with their corresponding reliability indices, are described in detail in the paper. The paper reports on results obtained from analyzing six different busbar schemes with redundant components.

Abstract-This paper presents a method for modelling the different modes of failures in a substation and feeder architecture along with updating the possible false tripping scenarios in it. A traditional approach to collectively assess the failure modes using reliability block diagram is reviewed, and the method is updated to count in the unaccounted false tripping scenarios. A generalizable radial feeder branching structure is adopted and the effect of total feeder length and number of feeders from each busbar is examined and modelled with the help of the updated reliability block diagram. The modelled trends are also studied from real-world substation architectures. Thus, the analysis attains an improved estimation of the complex hidden failure probabilities combining theoretical and practical models.Index Terms-Circuit breakers, control equipment, failure rate modelling, power distribution faults, power system control, power system reliability, substation protection.
