SELECTION OF NEUTRAL GROUNDING MODES IN POWER DISTRIBUTION NETWORK

Mingyan Liu

Abstract

The development situation of two kinds of neutral grounding via small resistance and arc suppression coil is described, the advantages and disadvantages of the two grounding modes are compared and the general thinking to select the neutral grounding mode is given. The influence of power network layout and transformer winding connection schemes on neutral grounding modes is analyzed. The authors opinions on the selection of grounding resistance value, its installation position, the optimization of the compensation of arc suppression coils are presented.
