Fast detection of energy flow direction
Fast method of identification of energy flow direction in electric power system is presented. The method is offering opportunity to get information about energy flow direction (current direction) in electric power system at the very beginning of transient process caused by fault, in a time of less than half of millisecond after the fault inception. This is for one order of magnitude shorter than now used methods. Here presented method could be very useful for applications in electric power system protection and control systems but it is not restricted to electric power system only.
