Abstract
In modern digital protection systems, a correlation technique is recently used for study and analysis. In this paper, a correlation technique is developed for fault detection, classification and direction discrimination. The proposed technique is able accurately to identify the different types of faults that may occur in synchronous generator stator winding. Three line-current measurements are required for both generator sides. The suggested technique performs the fault classification task within half-cycle. Thus, the algorithm is well suited for implementation in a digital generator protection scheme. The used technique is applied for El-kuriemat power station unit that produces 320 MVA. Alternative transient program (ATP) and MATLAB programs are used to implement the proposed technique in this paper.
