Migratory birds need coordinated protection

Science, 2016
In January, THE Supreme Court of Pakistan lifted the hunting ban on Houbara bustards ([ 1 ][1]), a bird categorized by the International Union for Conservation of Nature (IUCN) as Vulnerable ([ 2 ][2]). Frustrating ecologists and environmental groups, the local government argued that lifting the ban has economic benefits and direct bearing on foreign ...

Coordination of protective relays for the protection of micro-grid

2016 International Conference on Energy Efficient Technologies for Sustainability (ICEETS), 2016
For effective and efficient use of distributed generation (DG) for consumer at remote areas, the idea of micro-grid has been put forward. Micro-grid (MG) provides mobility to customer; dependability of conventional grid is reduced or even removed after successful implementation of DGs.

Review on protection coordination strategies and development of an effective protection coordination system for DC microgrid

2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014
In this paper, common DC-fault detection methods have been reviewed. Effects of two line-to-line and line-to-ground fault types from various fault locations to operation of the DC system are presented. In addition, operation principle, strong and weak points of four main types of protection devices (including fuses, no-fuse circuit breakers, power ...

Optimal coordination of protective relays

2013 International Conference on Power, Energy and Control (ICPEC), 2013
Protective relays are commonly used as an economical means for protecting power systems. The selection of appropriate settings of these relays under various system conditions plays an important role in timely removal of the faulty section of power system.

Intelligent method for protection coordination

2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies. Proceedings, 2004
This paper presents the application of artificial intelligence in protection coordination. It can substantially improve the coordination of protection relay operations. The relay settings and coordination requirements are formulated into a set of constraint equations and an objective function is developed to manage the relay settings by the time ...

Coordinating overcurrent protection devices

IEEE Computer Applications in Power, 1996
Distribution, substation, and plant engineers can benefit from using an overcurrent protection program in commercial, industrial, and utility applications to aid in clearing temporary faults and isolating permanent faults. In the time it normally takes to check one coordination scheme manually, dozens of alternatives can be evaluated using a graphics ...

Adaptive Protection Coordination for Steel Manufacturers Users

2019 IEEE Industry Applications Society Annual Meeting, 2019
This paper proposes a new adaptive protection setting methodology for steel manufacturer users considering the tap-to-tap varying current consumption. Minimizing the total clearing time of relays is computed adding the restriction of the incident energy to avoid hazard conditions.

A Coordinated Protection Strategy for Wind Integration

2018 Clemson University Power Systems Conference (PSC), 2018
High penetration of renewable energy sources (RESs) in power grid may introduce more fault scenarios due to the RES characteristics of uncertainty and variability. Based on relay protection and the coordination of relays, this paper developed a relay-based protection strategy to protect a wind turbine generation (WTG) system from short circuit ...

Model of coordination for multilayer protection switching

SPIE Proceedings, 2003
Networks add recovery to deliver reliable service between a source and destination. Reliable service is an uninterrupted data transfer between nodes, even if certain links or nodes are faulty. Recovery processes in multilayer networks might operate at the same time when faults propagate between layers during a common-cause failure.
