This paper deals with an algorithm, based on wavelet-Alienation coefficients for protection of wind farm connected distribution network, which takes the differential current signal of grid node and wind farm coupling node and uses it to identify and categorize the various faults.Abstract:
This paper deals with an algorithm, based on wavelet-Alienation coefficients for protection of wind farm connected distribution network. The proposed algorithm takes the differential current signal of grid node and wind farm coupling node. The Wavelet transform used to extract the approximation coefficients of all the three-phase current signals. Alienation coefficients of each differential phase current obtained over a half cycle is used to identify and categorize the various faults. A modified IEEE13 bus test feeder system used for simulation in MATLAB. Proposed technique tested for detection of all shunt faults at each bus of the distribution system.read more

Fault diagnosis in distribution networks with distributed generation
TL;DR: In this paper, a multi-agent based scheme for fault diagnosis in power distribution networks with distributed generators is proposed, where relay agents measure the bus currents at which they are located such that it can detect and classify the fault, and determine the fault location.

TL;DR: In this article, the voltage sag magnitude is obtained taking into account the voltage drop across (ZI), and the normal coordination procedure is obtained by comparing the sensitive equipment (SE) dropout curve with the timevoltage characteristic (TVC) of the protective device.
