PMU Based System Protection Scheme

2014 IEEE Electrical Power and Energy Conference, 2014
Phasor Measurement Units (PMUs) are being widely installed in modern power systems worldwide. The most important advantage of PMUs is their capability to provide fast, reliable and synchronized real-time measurements of different system parameters. This characteristic leads to an essential role of PMUs in real-time monitoring, advanced power system ...

Novel transmit protection scheme for ultrasound systems

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007
The problem of protecting or isolating extremely sensitive receive circuitry from high-voltage transmit circuitry is commonly addressed through the use of diode bridges, transformers, or high-voltage switches, which prove to be prohibitively expensive, bulky, and power consuming for use in portable, low-cost, battery-powered systems.

Enhanced protection security using system integrity protection scheme (SIPS)

2016 IEEE Power and Energy Society General Meeting (PESGM), 2016
Events such as faults, loss of load or generation may cause unwanted relay operations which initiate cascade tripping leading to system collapse. Security of power system protection is a major concern for utilities. A System Integrated Protection Scheme (SIPS) based approach is proposed for improving security of protection operations. Identification of

System Integrity Protection Scheme for Enhancing Backup Protection of Transmission Lines

IEEE Systems Journal, 2021
Contingencies such as faults, loss of generation or load may produce undesirable relay operations which can lead to cascade tripping causing system catastrophic failure. Thus, security of power system protection is a major concern for utilities. In this article, an approach based on system integrity protection scheme is proposed for enhancing the ...

Boundary Protection Scheme for HVDC Transmission System

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
HVDC has the advantages of lower cost and stronger controllability, and has been widely used in the optimal configuration of renewable energy and asynchronous interconnection of power grids. The protection of HVDC transmission lines has also become a hot topics. This paper proposed a novel boundary protection for HVDC line.

Protection Scheme for DC Microgrid Distribution System

Advanced Materials Research, 2012
The low voltage DC (LVDC) distribution system is a new concept and a promising technology to be used in the future smart distribution system having high level cost-efficiency and reliability. In this paper, a low-voltage (LV) DC microgrid protection system design is proposed. Usually, an LVDC microgrid must be connected to an ac grid through converters

Protection scheme for an LVDC distribution system

IET Conference Publications, 2009
The low voltage DC (LVDC) distribution system is a concept of new DC based distribution system. Safety of new distribution system needs to be equal or higher than traditional AC distribution systems [1]. This paper presents protection scheme for an LVDC distribution system.

Improvements in power system integrity protection schemes

10th IET International Conference on Developments in Power System Protection (DPSP 2010). Managing the Change, 2010
As the existing transmission system infrastructure is challenged to support loads beyond original design limits, the implementation of "wide area" Power System Protection Systems (PSPS) also called System Integrity Protection Schemes (SIPS) are often needed to maintain transmission system integrity.

Privacy protection schemes for fingerprint recognition systems

SPIE Proceedings, 2015
ABSTRACT The deployment of ngerprint recognition systems has always raised concerns related to personal privacy. A ngerprint is permanently associated with an individual and, generally, it cannot be reset if compromised in oneapplication. Given that ngerprints are not a secret, potential misuses besides personal recognition representprivacy threats and
