IEEE 30- Methods for Determining The Status Of MV Switching Devices Using Minimum Cost Criterion


This paper introduces a new method for evaluating
the status of medium-voltage (MV) switching devices by defining
two hybrid parameters. The device condition hybrid parameter
(DCHP) and the device importance hybrid parameter (DIHP) are
defined by using weighing factors. Three different methods were
applied for determining the DCHP, while the DIHP is determined
by using the differential evolution algorithm. Boundary values for
the DCHP are calculated on the basis of economic criterion regarding
minimum costs. The proposed approach was primarily developed
for applying modern MV switching devices maintenance,
but can also be used in network planning and for proper choosing
of MV switching devices. It is elucidated by an example.
