Application of synchronized phasor measurements in RPA devices of distribution networks

The paper discusses the efficiency of RPA devices application with support synchronized phasor measurements (SPM) at step-down substations and in 6-20 kV distribution networks. main part presents a description algorithm developed by authors for determining damaged cable line during single-phase ground faults (SGF) networks compensated isolated neutral. proposed makes it possible to realize reliable, fast-acting, selective SGF protection acting either on signal or trip. Based using SPM, an localization system can be created. This easier find network. report conditions this algorithm, which ensure stability reliability its operation under various parameters propose options improving allows expanding field application. results virtual modeling confirm effectiveness based SPM algorithm. final contains examples demonstrating other areas transformers, substations,
