This paper presents a method to identify a faulted section in a distribution network using voltage sags pattern characteristics. The method starts with fault analysis to establish analytical voltage sags database. When a fault occurs, the voltage sag at the monitored node is compared with the established voltage sags in the database to find all the possible faulted sections. Finally, the method applied...
This paper presents a new method for locating short-circuit fault in electrical distribution system. The method works by matching the actual voltage magnitude and phase angle with the simulated ones from fault analysis that stored in a database. The matching will give the possible faulty section/sections. A matching measurement algorithm is then applied to quantify the matching accuracy and to estimate...
This paper presents on an ongoing development of automated fault location software for distribution network. The proposed method of the software is able to identify the most possible faulty section based on voltage sags feature i.e. magnitude and phase shift. The actual voltage sags caused by fault is compares with simulated voltage sags stored in a database. The matching will give all possible faulty...
