Abstract :
In this paper, cumulative sum and moving sum based fault detection algorithms are presented for a power system relaying application. Simplicity and accuracy are the two attractive features for both of the methods. The methods are tested in a simple test system. When compared with conventional methods, it is found that integral based fault detection methods are more effective than the conventional ones. CUSUM method is not affected in the presence of noise, system frequency deviation and the other uncertainties. The moving sum method has a small detector output for the same conditions. But since the index value is high for this method, it can be accepted as negligible.
