Control and Protection of Distribution Network with Non-Utility Induction Generators

Abstract

In this paper, some topics related to the dynamic simulation and operations of Non-Utility Induction Generation (NUIG) are investigated. Various technical aspects related to the network conditions were analyzed mainly by computer simulation of a distribution network and NUIG units connected to it. The applied simulation tool was EMTP-RV, which is a commercial electromagnetic transient simulation program. This paper presents the guidelines to limit the self-excitation phenomenon of NUIGs in islanding conditions and proposes proper protection schemes for interconnection of NUIGs to the distribution networks.
