Abstract: This invention relates to a method of detecting faults on an electrical power line (7) and a sensor (5) for use in such a method. Preferably, the sensor is a line-mounted sensor (5). The method comprises the initial step of determining an initial impedance profile for the power line (7), and thereafter the method comprises the subsequent steps of the line-mounted sensor (5) transmitting a conducted communication signal (41) along the power line, receiving a reflected signal (43) particular to the transmitted communication signal and correlating the transmitted signal and the reflected signal. By correlating the signals, it is possible to determine the actual impedance of the power line. The actual impedance of the power line may then be compared with the initial impedance profile and it is possible to ascertain whether a fault exists on the power line. Preferably, the method uses an adaptive filter to determine the location of the fault.

Abstract: The present invention relates to a method of monitoring line faults in a medium voltage network (1) of the type comprising an electricity generating plant (3) supplying electricity to a plurality of customers over a network of medium voltage power lines (5), a control centre computer (9) and a plurality of measurement sensors (7) located remote from the electricity generating plant on the medium voltage power lines, each of the measurement sensors (7) further comprising three individual measurement units, each measurement unit mounted on a different phase of the medium voltage power line (5) with respect to the other measurement units of that measurement sensor, and each measurement sensor (7) having means to communicate with the control centre computer (9). The method includes the steps of synchronizing the measurement sensors (7) and thereafter calculating the out of balance current for the medium voltage line (5) on a cycle by cycle basis. On the measurement sensor (7) detecting a fault in the line a line fault measurement report is sent to a control centre computer (9) for further analysis. The method allows for the determination of the likely cause of a fault as well as the likely location of a fault.

Abstract: This invention relates to a method and system for locating line faults in a medium voltage network (3). Heretofore, the known methods and systems provided relatively limited resolution of fault location. Typically, the fault location information was limited to a distance from the substation (5). In complex medium voltage networks with branching, these systems and methods are not ideal as faults could potentially be in a number of different locations, spread out over a large area. According to the present invention, line mounted sensors (23(a)-23(I) are positioned both upstream and downstream of each of the branch points (11 (a)-11 (e), 29(a)-29(b) and this enables a more accurate determination of the location of the fault in the medium voltage net-work. Furthermore, artificial neural networks are employed to improve detection and location of faults in the medium voltage net-work.

Abstract: A system that includes a controller configured to receive data corresponding to at least a portion of a power system and one or more sensor measurements from one or more sensors in the power system. The controller may then generate a model of the power system based on at least a portion of the data and at least a portion of the sensor measurements such that the model may include one or more model measurements that correspond to the sensor measurements. After generating the model of the power system, the controller may determine one or more correction factors for the sensor measurements based on at least a portion of the sensor measurements and the model measurements, apply the correction factors to the sensor measurements to generate corrected sensor measurements, and determine one or more properties of the power system based on the corrected sensor measurements.
