| EDSA's Reliability Analysis program provides a proven, powerful solution for a
wide range of reliability 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 Frequency
Index (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.
