Effect of relay characteristics in optimum coordination of overcurrent relays

2020 IEEE Students Conference on Engineering & Systems (SCES), 2020
The coordination of overcurrent relays require minimum tripping time at maximum fault current while backup relays, experiencing low fault current, follow the coordination criteria. The challenges arise as overcurrent characteristics perform diversely according to the magnitude of fault currents.

Relay coordination in microgrid

2017 International Conference on Computing Methodologies and Communication (ICCMC), 2017
Microgrids has many environmental and economic benefits but their implementation has great technical challenges in protection, energy management and control. MG consist of a number of distributed generators (DGs). Distribution system protection is the most important technical aspects in the microgrid.

Automating relay coordination

IEEE Computer Applications in Power, 1994
The process of setting relays and checking the coordination between primary and backup relays has always been a time consuming process. Automation of various steps of relay setting and checking is easing the tedium of this process for engineers at Consumers Power company.

Optimal coordination of directional overcurrent relay coordination

IEEE Power Engineering Society General Meeting, 2005, 2005
Directional overcurrent relays are used to protect interconnected power systems and looped distribution systems. Several techniques and formulations have been proposed to solve the directional overcurrent relay problem. In this paper, the proposed formulations for relay coordination problem are discussed.

Improved relay coordination and relay response time by integrating the relay functions

2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002
This paper describes a practical method for improving relay coordination for high current faults by reducing the relay operating times by integrating the relay functions. This results in reduced fault duration at high currents, which minimizes equipment damage.

Review: Methods for relay coordination

2017 International Conference on Computing Methodologies and Communication (ICCMC), 2017
Reliability of the power system degrades with abnormal operating condition of the protective system caused due to overvoltage, under-frequency, overload etc. which may leads to interruption of the supply, and may damage equipment's connected to the system.

Relay coordination for distribution system

2016 Second International Conference on Science Technology Engineering and Management (ICONSTEM), 2016
In power system protection relay and circuit breakers is the major instrument for large interconnected power system. We need proper protection to isolate the faulted region from healthier network. When two protective apparatus installed in series have certain characteristics, which provide a specified operating sequence, they are said to be coordinated
