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.

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.

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

Centralized interference coordination in relay-enhanced networks

2012 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2012
In this work, we investigate the issue of interference coordination in relay-enhanced networks. We focus on Type 1 in-band relays as proposed for LTE-Advanced, where the base station and the relay nodes share the same frequency for the backhaul and relay access link.

Relay aided coordinated beamforming and interference neutralization

2017 Information Theory and Applications Workshop (ITA), 2017
We consider the Multi-Input Single Output (MISO) Interfering Broadcast Channel (IBC), in other words the multi-user (MU) multi-cell half duplex downlink in a cellular or heterogeneous network, aided by a full duplex MIMO relay. The Degrees of Freedom (DoF) are analyzed for joint coordinated beamforming by the base stations and interference ...

User Allocation and Precoder Design for Coordinated Relaying

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
Relays are used in the current standards to enhance the cell throughput and coverage. Often, the relays are evaluated without considering the overhead involved in providing the relay with the data prior to the transmission. In this paper, we evaluate the system performance by considering the duplexing loss with over- the-air transmission (OTA) for ...

Impact of distributed generation on relay coordination

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

Mars relay coordination lessons learned

2005 IEEE Aerospace Conference, 2005
The Mission Management Office at the Jet Propulsion Laboratory was tasked with coordinating the relay of data between multiple spacecraft at Mars in support of the Mars exploration rover missions in early 2004. The confluence of three orbiters (Mars Global Surveyor, Mars Odyssey, and Mars Express), two rovers (Spirit and Opportunity), and one lander ...

Overcurrent relays coordination for commercial building

2013 IEEE 7th International Power Engineering and Optimization Conference (PEOCO), 2013
This paper presents an overcurrent relays coordination study for an 11 kV commercial building in southern Malaysia. Nevertheless, the actual study that covers the overcurrent relays, earth fault relays and earth leakage relays were executed by providing optimum and functionable relay settings prior to commissioning of the building.

Relay Location Optimization and Relay Coordination in Multi-hop Cognitive Radio Networks

2019
Relay cooperative transmission can increase the transmission distance and reduce the transmit power. In this paper, three transmission modes are discussed: direct mode, single relay mode and dual relay mode. Each of the transmission schemes is optimized to obtain the maximum channel capacity.
