Central or Local Compensation of Earth-Fault Currents in Non-Effectively Earthed Distribution Systems

Guldbrand, Anna LU and Samuelsson, Olof LU (2007) Power Tech 2007 p.1129-1134
Abstract
Centralized Petersen coil earthing in networks with

extensive use of underground cable involves flow of large

quantities of reactive earth fault current. In networks with long

radial cable feeders this creates problems involving active losses

and active and reactive earth fault current. One possible solution

to the problem is the use of local compensation. This paper aims

at understanding the limitations of traditionally compensated

networks and compares these to networks that are locally

compensated. This is done through analytical calculations and

PSCAD simulations that are combined with results from a

project studying cables in Swedish distribution... (More)
