Impact of rural design, operating, and restoration practices on the costs of service interruptions

摘要

Service reliability indices of individual customers are shown to be dependent upon their physical location within a distribution circuit configuration, the protective equipment used in a predefined protection-coordination scheme, and the activities involved in isolating and restoring continuity of service following a circuit outage. The cost of service interruptions to individual customers is dependent upon the duration of the service interruptions, which is dependent upon many of the factors already listed. The 'zone branch concept' is applied to evaluate individual service reliability indices of a distribution circuit and to demonstrate the significant impact of various operating and restoration practices on service reliability levels and the costs of these interruptions. A detailed list of references on the costs of interruptions to residential, commercial, and industrial customers is presented.
