چکیده :
The overcurrent relay (OCR) is the major device to protect the distribution network feeder. The OCR issues increase with distributed generation (DG) embedded in active distribution network (ADN). In addition, high impedance fault (HIF) has been challenging to properly detect the fault by current relay in ADN. The blinding areas lead to a delay or non-tripping in the OCR. The typical method to cover the blinding area is the increasing sensitivity of relay settings. Changes in the settings of the protective relays may cause challenges to protect ADN. Most of the modern protection relays are digital multifunction. The relays can activate multiple protections, simultaneously. This paper presents a simple and economical solution to protect the fault in blinding areas by the OCR and thermal overload relay. The blind possibility points are determined in the case study by changing the fault impedances and DG presence. The simulations are carried out on a realistic case study using DIgSILENT software.
