Reliability: Result

The results may be examined as follows:

in the on-line diagram

using Results | Survey.

using Results | Details.

using Results | Graph.

 

One-line diagram

For each component the plotted results are (defined in Tools | Views):

F: .../year                Outage rate

D: ... min                Mean outage duration

P: ... min/year        Outage duration per year

P: ... %                      Outage probability

 

For each element the Energy Not Served is plotted:

ENS: ... kWh/year

 

For each load or transformer load the customer outage is plotted:

P*BC: ... min/year (P x number of large customers)

P*SC: ... min/year (P x number of small customers)

 

Results | Survey

The mean reliability results are presented per component type for the selected components and the whole network.

 

Results | Details

For a selected node is presented:

Name

Reliability results

 

After clicking the 'Details' button a table shows:

Failing component causing the non availability of the selected component

Remarks, for example the indication that here this is the effect of a refusing switch

Outage frequency F

Outage duration D

Outage probability P

Recovery phase, the action that leads to restoration of the supply

D (Tsig + Tsp + Tlok + Tiso + Tins + Toms + Tnr): individual recovery durations that sum up to D [min]. These are:

 Tsig  : time to signal a fault

 Tsp   : time to activate the fault recovery team

 Tlok  : time to locate the fault

 Tiso  : time to isolate the fault

 Tins  : time to close switches for the recovery

 Toms: time to re-route for the recovery

 Tnr   : time for emergency generator or for repair

Summation of outage frequency and outage probability.

 

With these data the greatest cause of the non-availability frequency or the non-availability duration can easily be found.

 

Results | Graph

The mean reliability results for frequency, duration and probability are presented in bar charts. The type of reliability result can be selected with the selection box. The components are sorted as indicated.

By clicking on a bar in a results bar chart, the user jumps directly to the concerning object in the one-line editor.

The results may be compared with results of another calculation, is saved with Results | Save. Use the check-box "Saved".

 

Results | Save

With Results | Save the results of a calculation can be saved to compare with another calculation result in Results | Graph.

 

Export

Almost all calculated results can be exported to Excel. In fact, the export is a fixed format report of all objects on three sheets: nodes, branches and elements.
