Abstract
THE PURPOSE. paper show digital system for monitoring of single-phase earth faults on overhead power lines of 10 kV voltage in distribution power grids with an isolated neutral mode. METHODS. Digital system analyze frequency and amplitude of higher harmonics of voltage and current. The digital monitoring system includes the features of technical solutions for the selection of higher harmonics. RESULTS. Simultaneously, the paper shows the layout solutions for connecting a monitoring system to the control circuits on the10 kV side of 110/10 kV voltage substation. Software implemented for the far monitoring of the power grids and can detect of various types of single-phase earth faults. CONCLUSION. Software base on the mathematical models, as well as taking into account the results of a series of full-scale experiments of modeling various types of single-phase earth faults in the distribution power grids. The main functionalities the developed software presented for the description of solutions. Paper show further directions of research of the diagnostics and monitoring of single-phase earth faults in distribution power grids with overhead power lines based on the analysis of higher harmonic components.
