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.

“…But, if the fault is a permanent one, the fuse is melt after some interval to clear the fault. Then, the recloser slowmode acts as backup protection for the fuse [6], [7]. So, a proper fuse-recloser coordination should be set to guarantee a reliable operation for the network and save the unnecessary fuse melting [6]- [8].…”

Sustained Coordination of Devices in a Two-Layer Protection Scheme for DGs-Integrated Distribution Network Considering System Dynamics

Distribution networks are usually protected by directional overcurrent relays (DOCRs). Besides, autoreclosers and fuses can be used for protecting lateral feeders to minimize power cuts. Coordinated operation of protection device must be maintained to ensure optimal fault isolation. Typically, steady-state fault current and static protective device characteristics are used to determine optimal settings of devices such that coordinated operation is verified. Sine fault current is not a steady signal and protection devices have dynamic behaviors, the conventionally-determined settings of devices can lead to loss of coordination jeopardizing system reliability. In this paper, a two-layer protection scheme is proposed for a distribution network with distributed generators (DGs). The first layer has DOCRs to protect main feeders. The second has autoreclosers and fuses to protect lateral feeders. Optimal settings of devices are determined to achieve both local-layer and inter-layer coordination of devices by constrained nonlinear optimization. Full dynamic models of every component and transient data of fault current are considered. Furthermore, to sustain coordination under DGs, a hybrid superconducting fault current limiter (HSFCL) with high temperature superconducting resistive element is connected in series to each DG. Dynamic modeling-based HSFCL cost minimization is searched by multi-objective optimization. The approach is applied to two distribution networks and simulation results are analyzed.

“…Therefore, if there is no coordination, two actions are recommended: finding a better location for the DG or changing the recloser settings. The work of Dawoud et al (2017) proposes two solutions for the adaptive adjustment of the recloser. The first one, offline, can be applied when there are no frequent changes in the DS.…”

The use of advanced communication and computation technologies, together with the need to make systems more secure and reliable, pushes for the development of new methods of protection that take into consideration new features. However, the advances must reconcile with analog equipment already present in the protection systems, such as fuses. In this sense, this work proposes the development of a self-adjusting recloser, aiming at ecient coordination with the fuse involved in the fault. For this purpose, the automatic reconguration of the Time Dial (TD) of the delayed characteristic curve of the recloser is carried out based on the current measurements obtained in the fuse involved in the short circuit. The proposed method provides signicant reductions in operating times due to the recloser delayed characteristic curve, which, in turn, reduces the chances of damages to the system components.
