Optimal recloser placement

System reliability is an integral part of distribution system planning and operation. Growing energy demands, aging infrastructure and network expansion are among the factors that influence system reliability.

Eaton's CYME Optimal Recloser Placement Analysis module offers a comprehensive assessment and proposes solutions that correspond to your criteria. The module was designed to help engineers handle the complexity of system reliability improvement. The analysis is built upon the robust CYME Reliability Assessment module (required). It takes into account different objectives and criteria, studies the reliability indices, evaluates the expected improvement and finds the best solution.

Comprehensive analysis

The Optimal Recloser Placement analysis offers a weighted-objective optimization technique which improves:

SAIDI (System Average Interruption Duration Index)
SAIFI (System Average Interruption Frequency Index)
User-defined criteria based on CYME keyword expressions

The analysis also provides two optimization methods:

Sequential Search
Iterative Search

Features

The analysis is designed to take into consideration a wide-range of user-defined criteria:

Define the number of reclosers
Specify a searching distance for the possibility of adding a recloser
Evaluate locations downstream to feeders, specific sections or specific nodes
Choose the recloser to be used from the equipment library
Choose operation mode and define reclose settings
Include user-defined constraints (ex: loading limits, distance between reclosers, etc.)
Ignore specific locations

Results

Optimal Recloser Placement analysis generates results in report formats. Reports include:

A summary of the reliability indices of the initial network compared to the optimal solution network
Detailed report which details each recloser to be added
Reliability assessment reports

Options are also available to customize these reports.

A one-line diagram also helps users visualize results.

Users can choose to highlight the evaluated sections via color-coding. Suggested reclosers can be applied to the network via buttons in the report.

Eaton’s CYME Optimal Recloser Regulator Placement module helps to determine the optimal locations on which to install reclosers.
