Contributions to the rational method of neutral earthing with MATLAB+SIMULINK

Abstract

Till present day the problem of electricity networks neutral of medium voltage treatment is argued hotly by the specialists in energetics. The present problem is analyzed from different points of view in numerous scientific articles: safety factor of consumers supply with electric energy, current magnitude in the place of defect and overvoltages on the healthy phases of one phase earth connection; protection schemes through the relays of contra earth connections; personnel and electrical equipment security of earth one-phased connections etc.
