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.

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.

Coordinated protection of DC microgrids

2018
DC power systems have been investigated for transmission and distribution systems due to the advantages such as improved efficiency, reliability, and simpler configuration, as well as increasing DC-based distributed generation, energy storage, and loads.

Overcurrent protective device coordination by computer

IEEE Transactions on Industry Applications, 1982
Overcurrent protective device coordination is defined, and the advantages of computerizing this process are explained. A computer program written by the authors, who are engineers responsible for performing coordination studies, is discussed. The program was written with emphasis on engineering flexibility.

Overvoltage protection and insulation coordination

2015
The surge arrester at the line entrance must be installed for the protection from fast-front overvoltages. The selected surge arrester in the simulation model has a sufficient performance for the assumed lightning strike and other conditions. The standard rated lightning impulse withstand voltage can be selected from 1,050, 1,175, 1,300, and 1,425 kV ...

Coordinating Plans for Fire Protection Facilities

Journal of Forestry, 1939
Abstract The author here describes an attack on a very timely and important problem. If a fire administrator wants to obtain maximum protection from fire on a forest unit at the least annual cost, what should he do: build more lookouts? construct more roads and trails? or put more fire guards or fire fighters in the area?
