Adaptive power-line disturbance detection scheme using a prediction error filter and a stop-and-go CA CFAR detector

This paper presents a new power-line disturbance detection algorithm. The utilized recursive least square (RLS) prediction error lter extracts the power-line disturbance signal from recorded data, and the modi ed stop-and-go cell average constant false alarm rate (CA CFAR) detector makes a decision based on the squared output of the previous stage. The detection performance of the proposed algorithm is determined by simulations, and actual high voltage transmission line data is utilized to demonstrate the performance of the proposed algorithm.
