improvement of power quality in four-wire ‎distribution systems

This paper explores the inherent characteristics of multigrounded three-phase four-wire distribution systems under unbalanced situations. as a result, the mechanism of profile voltage in mgn feeders becomes difficult to understand. the simulation tool that been used for this paper is matlab under windows platform. in this paper the equivalent model of a full-scale multi-grounded distribution system implemented by matlab is introduced. the results are expected to help utility engineers to understand the impact of mgn on distribution system operations.this paper explores the inherent characteristics of multigrounded three-phase four-wire distribution systems under unbalanced situations. as a result, the mechanism of profile voltage in mgn feeders becomes difficult to understand. the simulation tool that been used for this paper is matlab under windows platform. in this paper the equivalent model of a full-scale multi-grounded distribution system implemented by matlab is introduced. the results are expected to help utility engineers to understand the impact of mgn on distribution system operations.
