Solution: Medium voltage architecture dependability design for large sites

 
 

 

 

Value proposition


Main drivers:
  • Availability & reliability of Electrical Supply
  • Understand and identify risks
  • Optimise architecture, compare solutions, highlight weak points
  • Design redundancies and back-up configurations
  • Optimize maintenance plan

Value proposition:

  • Overall target unavailability < 2 hours per year P(t) < 2,28.10-4
  • Availability better than 99,977%
  • Overall target unreliability < 1 occurrence per year leq (t) < 1,14.10-4 /h

Differentiation factors:
  • Target availability and reliability are achieved thanks to
    - Taking into account dependability issues from the early stage of the project
    - Redundancy implemented at architecture level
    - Automatic reconfiguration
    - Process equipment dispatching
    - Failure detection system
