22.9 kV-y 실긍장 배전선로 모의를 위한 집중정수회로의 설계

The Design of Lumped Constant Circuit for the Simulation of A Real 22.9 kV-y Distribution Line

When we perform the test related to the power distribution system such as artificial fault test, protective coordination test, distribution automation test in short length test line, Lumped Constant Circuit, a kind of variable impedance, should be attached to the test line in order to make it equivalent to a real line in length electrically. In this paper we designed the positive sequence and zero sequence Lumped Constant Circuit with optimized inductor and resister for the modification of long, 16km, distribution line, when they are attached to the short, 4km, distribution test line.
