abstract
This paper illustrates a frequency and duration approach to short term reliability evaluation. The concepts of interval frequency and fractional duration are defined and numerical techniques for their calculation are developed. These definitions and techniques can be applied to any system of repairable or non-repairable components but they become especially significant in the area of spinning reserve calculations. The development of the generation model and its convolution with the forecast load is outlined in detail. These indices have been interpreted so as to give a better insight into their physical meaning and their significance has been illustrated by application to a hypothetical system.
