Advanced Fault Analysis

FLASH® computes fault levels and breaker duties in a power transmission system. Its advanced, modern design makes the package uniquely suitable for on-line applications in energy management systems in addition to the traditional system planning function.

The principal features of FLASH are:

  • Accurate system modeling
  • Generalized network description
  • Comprehensive breaker duty evaluations
  • Computation speed optimized for online applications

FLASH performs the following types of fault analysis:

  • Bus fault analysis—rapidly calculates the current for a fault at each bus or designated subset of buses. This analysis may optionally be used as a screening mode for open branch analysis
  • Open branch analysis—simulates the successive opening of each branch connected to the faulted bus
  • Circuit group analysis—performs a physically realistic form of open-branch analysis by opening the remote-end circuit breakers connected to each faulted bus section

FLASH was developed for GE Energy Control Systems and the National Grid Company (U.K.), for online implementation in the latter’s national control center.
