Roy Billinton Test System (RBTS)

Engineering models and SUBREL study files

Original native files are organized by RBTS configuration and study purpose. Each listed file is a separately supplied engineering artifact; no unsupported conversion formats have been added. File publication status: all fifteen contributed engineering files are now hosted on the GR main website and individually downloadable. The original five station JPEG diagrams above are also available.

Basic RBTS — no detailed substations

Configuration figure: RBTS No Stations.jpg

The original six-bus representation is distinct from the detailed station models.

Breaker-and-a-half substations

Configuration figure: RBTS Breaker One & One Half.jpg

The original contributor-supplied PWB and PWD are a matching model/display pair by filename.

Ring substations

Configuration figure: RBTS Ring.jpg

The RAW file includes explicit additional switching nodes compared with the six-bus base case.

Ring-substation SUBREL study

These are related SUBREL project/database/export files; the 484-case contingency export scope must not be confused with the broader historical workbook.

Three-configuration historical reliability results

Historical SUBREL results pending independent InfraRel reproduction. Summary values are already available below.

Other station figures without matching model files in this collection

Breaker one-and-one-third and double-bus double-breaker (DBDB) are available as original JPEG diagrams. Corresponding PWB/PWD pairs have not been supplied and are not implied.

Historical SUBREL comparison: three RBTS substation arrangements

Historical study · Supplied workbook · Not independently reproduced

This worked example compares the original RBTS without detailed substations, a breaker-and-a-half arrangement, and a ring-substation arrangement. Results below are transcribed from the author's RBTS N-2F N-1S SUBREL Results.xlsx workbook. They are not results from InfraRel. The study scope includes up to N-2 forced faults and N-1 stuck-breaker conditions as described in the workbook, subject to configuration-specific enumeration.

Reported system reliability indices

Contingency enumeration

Supporting SUBREL files and planned reproducibility

A separate ring-substation SUBREL project and Microsoft Access database, with PSS/E and PowerWorld contingency exports, have been supplied and preserved. A 484-case ring N-1 fault / stuck-breaker export set is not equivalent to the complete 12,577-credible-contingency enumeration shown above; the study scopes must be reconciled before comparison. Original project/database and model binaries are being prepared for GR-domain distribution.
