“…The amount of fault current contributed by DER varies widely [32,34]. Generally, DER are connected with network via power converter, so the fault behaviour are depends on converter controller and its design parameter [35]. The contribution of Inverter Based Distributed Generation (IBDG) to the system's fault current level is the lowest [33].…”

This paper presents a review of an adaptive overcurrent protection scheme in a distribution network with the integration of distributed energy resources. The rapid integration of distributed energy resources brings challenges to the existing overcurrent protection system. The impacts are change in fault current magnitude and direction of current flow from radial to the multi-source dynamic network, which causes changes in network topology, inaccurate fault detection, and loss of coordination among protection systems. In this paper, the solution identified for reliable operation of overcurrent protection in the distribution network are network topology estimation, fault detection, and adaptive coordination.

This paper addresses the behaviour of an IEEE (Institute of Electrical and Electronics Engineers) test network when distributed injections are added to the distribution network. The penetration of different dispersed generation technologies, modifies the distribution system characteristics, with impact on a number of parameters, depending on their size and location on the network. For this purpose, this paper comprises three case studies: in the first case an exhaustive analysis is carried out of the occurrence of faults throughout the network, along with the introduction of distributed generators; in the second case the network behavior is assessed against the use of three of the most commonly used types of generators based on rotating machines; in the third case study an evaluation is made of the network performance when the three types of DG (distributed generation) units are distributed in multiple buses. In all cases the protection system is analyzed with the aim of ensuring coordination among the protection devices. All simulations are performed using the Power Factory software package from DigSILENT. From the simulation results, conclusions are drawn that provide insights into the behaviour of protection systems, highlighting the limitations of the original protections and coordination with different distributed generators technologies.

“…An OC relay trip settings are determined by "pickup current (Ip)" and "time delay" parameters. Pickup current is the threshold current value and is sensed by current level detection principle, which has to be exceeded for relay trip [27].…”

“…The previous reports have focused more on the problems that are created by adding DG to the distribution networks, such as blind protection, sympathetic tripping and failure of reclosing [4,5,7,8]. In [10,12,22,[24][25][26][27], the recloser settings and coordination with the other protective devices such as fuses and overcurrent relays were studied. The researchers in one study [14] replaced a new solid dielectric with hydraulic reclosers and showed the benefits of this replacement.…”

Impact of Recloser on Protecting Blind Areas of Distribution Network in the Presence of Distributed Generation

The protection relay issues increase with the penetration of distributed generation (DG) units in distribution networks. Blind protection, sympathetic tripping and failure of reclosing are the frequent problems that are created by adding DG to the distribution networks. This research focuses on the impact of reclosers on overcurrent relay blind protection areas with DGs embedded in the distribution network. The protection blinding in overcurrent relays leads to a delay or non-tripping of the relay. The conventional solution for the blinding issue is to increase the sensitivity in the relay settings. The variation of relay settings may cause problems in the distribution network. This paper investigates the effect of reclosers on eliminating blind areas and improves the reliability in the presence of DG. In this way, possible blind points of the case study are detected, and recloser relays are then installed in appropriate locations. The case study is based on realistic data of a distribution network. The DG consists of two generators with a capacity of 4 MW. The simulation is performed in DIgSILENT software.
