The Paladin® DesignBase™ Solutions Module
library includes proven, powerful solutions a wide range
of reliability and capacity tasks, including allowing
engineers to accurately and efficiently evaluate the
reliability of electrical distribution systems.
Some of the factors that can be evaluated include:
-
Load point average failure
frequency
-
Average outage duration
-
Annual availability
-
System Average Interruption
FrequencyIndex (SAIFI)
-
System Average Interruption
Duration Index (SAIDI) and Customer Average
Interruption Duration Index (CAIDI)
-
Average Service Availability
Index (ASAI)
-
Energy Not Supplied (ENS)
-
Average Energy Not Supplied
(AENS)

These indices provide engineers with important information
from not only an individual customer's perspective,
but from an overall view of the entire distribution
system's performance. Distribution networks can also
include both radial and meshed networks.
Reliability worth and cost assessments are conducted
by incorporating the basic load point indices and composite
customer damage function:
- Reliability cost is related to
the investment cost used to increase total system
reliability
- Reliability worth is associated
with the interruption and outage costs to customers
- Customer cost associated with
a particular outage at a specific point in the the
system involves an amalgamation of the costs associated
with the customers affected by the interruption at
that point in the system (composite customer damage
function)
Engineers are not required to build a unique model
for distribution system reliability. Rather, the same
file created for short circuit, load flow, and device
coordination can be used, as we previous existing models. |
