In this article, the algorithm of reliability evaluation
of electricity supply systems operation is presented. It includes
evaluation of the reliability of consumer’s electricity supply and
the reliability of power generation by the local power plants.
Proposed algorithm is based on the method of sequential network
reduction and allows calculating the reliability indices of the
selected consumer or of the certain point of power distribution.
This algorithm is implemented in the program complex (PC)
KATRAN. The calculation of reliability indices allows assessing
the consumer’s outage cost and the interruption costs of the
enterprise’s power plants
