Overvoltages under single-phase fault conditions in the high voltage grids

摘要: The requirements for modern power systems are directly related to the need continuous supply consumers while meeting electricity quality. Planned and unplanned outages occur in system, they affecting normal operation maintenance of equipment system. This determines study processes regime parameters case failures Due specific characteristics model research a software environment is preferred way investigations system transients. paper focus on change single-phase faults 220 kV electrical network depending place failure relay protection. investigation was performed through ATP-EMTP environment.
