Maximum Capacities of Distributed Generation in order to Avoid Failures of the Overcurrent Relay Coordination on a Distribution Networks
Abstract: The installation of
a Distributed Generation (DG) in a distribution system often changes the
direction and magnitude of current for normal and faulted conditions. The
changes may affect the existing protection system hence it may not work as
intended to after the installation. Since DG capacity is often small, it will
not be economical to invest in the changing/replacement of the protection
system. For that reason, this paper proposes a methodology to find maximum
capacities of DGs that can be installed without cause failures to the existing
protection operation and its coordination. A case study of a distribution
network in West Sumatera is present to illustrate the methodology. The results
show that the more downstream of buses from the grid, the less DG capacity that
can be installed.
