Determination of the Loads Restoration Sequence Taking into Account the Cost of Interruption Electrical Service (Consideration of the Deviation of the Cost of Interruptions of Electrical Service)

摘要

In the restoration state of a power system, the time taken for a dropped generator to parallel in, and the cost of interruption of electrical service vary according to the, operating conditions just before the fault concerned, the amount of the load expected to be consumed during the fault and accidental factors. In this paper, the authors propose a method of determining　the loads restoration sequence which takes into account the cost of interruption of electrical service, in which the above factors are considered. The authors develop a new calculating method which takes into account the distributions of these values. Comparing this method to the one previously presented which used fixed expected values，the authors confirm that the former method is fully capable of determining the loads restoration sequence.
