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 ...

Deep-sea protection: Coordinate efforts

Science, 2014
The plight of deep-sea ecosystems in areas beyond national jurisdiction (ABNJ) has been persistently overlooked. As a consequence, they remain very poorly protected despite calls for action dating back more than a decade. In 2002, the United Nations General Assembly called upon intergovernmental organizations including the Food and Agriculture ...

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 ...

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 ...

Protective Device Coordination Expert System

IEEE Transactions on Power Delivery, 1991
The Protective Device Coordination Expert System (PDCES) software is presented. It helps electric distribution engineers correct miscoordinated protective device pairs. PDCES was prototyped as a component of the Pacific Gas & Electric Company's Electric Distribution Planning Analysis (EDPLAN) system, an in-house engineering tool for analyzing electric ...

Zone 2 distance protection coordination with distribution feeder protection

2015 68th Annual Conference for Protective Relay Engineers, 2015
In recent years, renewable energy generators have been widely promoted in Ontario to offset their polluting counterparts. Due to connection cost of these generations, most of the renewable generation stations are connected to Hydro One transmission system at nearby HV transmission lines.
