FLASH® Advanced Fault Analysis

FLASH® computes fault levels and breaker duties in a power transmission system. It is primarily deployed as an online application in energy management systems delivered by GE Energy.

FLASH can also be used as a study tool on a standalone workstation.

Principal features include:

• Accurate system modeling
• Generalized network description
• Comprehensive breaker duty evaluations
• Optimized computation speed 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
