Assessment And Restoration of Major System Damage
MARS ® (Management, Assessment and Restoration of Service) is a Windows-based innovative software that designs an integrated restoration plan following a devastating event such as such as an ice or wind storm, flood, earthquake, loss of transmission, or loss of major substations. MARS is based on restoration "best practices", assisting where the complexity of restoration issues overpowers human ability.
MARS redesigns a utility's system to isolate damaged wire and transfer priority customers to energized circuits. It reserves capacity on the redesigned circuits to pickup customers following each day's repairs. Next, it creates maps, field switching orders, and a prioritized list of work for line repair crews. MARS predicts restoration dates for all wire out of service, which can be used to keep customer informed.
MARS uses a real-time electrical model and a multi-objective reconfiguration algorithm to find the single, best restoration plan, not a long list of options. The MARS model is shared with the popular CYME CYMDIST distribution planning software. The shared model contains normal load-flow model components, plus damage locations, work time estimates, available crew hours, customer counts, and priority customer locations.
Large cost savings can be achieved when MARS models are also used for CYMDIST engineering studies, such as circuit growth (overload or low voltage), capacitor and switch placement, fuse coordination, reliability, etc.
MARS' integrated solutions solve multiple problems that are essential for a good restoration:
- Automates “Best Practice” damage restoration methods.
- Plans circuit switching, provides fastest restoration.
- Provides overview of damages for news media (with estimated restoration date for each area).
- Creates switching orders and maps, which guides the isolation of damages, and the transfer of priority customers to working circuits.
- Prioritizes work for daily crew assignment with instructions on connecting loads after work is completed. These instructions may include rearrangements as restoration progresses.
- Inspect and reconfigure circuits:
- Identify major damages.
- Design new circuits, connecting available facilities.
- MARS guides switching crewss how to create the new circuits. It provides switching orders and maps for crews performing the work.
- Repair damages by priority:
- Prioritize restoration repair jobs.
- Create work order and map for each repair job.
- Obtain switching orders to reconnect load after repairs completed.
- Track and report actual progress.
In a case study, MARS restored service to 80% of the customers in 12 hours, instead of 54 hours for the normal method (Circuit Priority Restoration). The first 10 hours are spent inspecting for damages, calculating new circuits, and distributing instructions to switch men.
