System integrity protection scheme for Southern grid
2014 6th IEEE Power India International Conference (PIICON), 2014This paper discusses about SIPS for Southern grid in India which involves the identification and ranking of the most severe contingencies of grid elements in the network which may affect the grid if they go out of the system at any given operating condition or time of day.

Hitless Switching Scheme for Protected PON System
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008The passive optical network (PON) shares feeder transmission facilities to provide broadband services economically. To enhance PON survivability, ITU-T Rec. G.983.5 defines some protection switching methods. These methods, however, always bring about signal loss when switching is performed.

A New Horizon for System Protection Systems Schemes
IEEE Power Engineering Review, 2002Interconnected grid operation, control, and security will be revolutionized by a system protection scheme that safeguards the grid's integrity by adapting its responses to the most severe unforeseen disturbances. The new approach takes advantage of power system resilience to the initial impact of even the most severe disturbances.

Enhanced Protection Security Using the System Integrity Protection Scheme (SIPS)
IEEE Transactions on Power Delivery, 2016Events, 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-based approach is proposed for improving the security of protection operations.

A Patient Privacy Protection Scheme for Medical Information System
Journal of Medical Systems, 2013In medical information systems, there are a lot of confidential information about patient privacy. It is therefore an important problem how to prevent patient's personal privacy information from being disclosed. Although traditional security protection strategies (such as identity authentication and authorization access control) can well ensure data ...

Undercurrent Protection Power System: A Novel Ground-Fault Protection Relay Scheme
IEEE Industry Applications Magazine, 2015THE NATIONAL ELECTRICAL CODE (NEC) [1] requires that ground-fault protection of equipment be provided when the building service disconnecting rating becomes 1,000 A or higher. To meet such a requirement, generally, the main service breaker is specified with ground-fault protection capability.

Reliability evaluation of a taipower system protection scheme
IEEE PES Power Systems Conference and Exposition, 2004., 2005In order to prevent major blackout and enhance system reliability, various types of system protection schemes have been implemented by the utilities around the world. One of the main concerns in the design of a system protection scheme is to assure whether the system could fit with the reliability requirements specification.

Modelling issues of system protection schemes in energy management systems
2008 IEEE Canada Electric Power Conference, 2008As more and more utilities are using / examining use of System Protection Schemes (SPS), also referred as Remedial Action Schemes (RAS), Energy Management System (EMS) vendors started looking at SPS schemes more seriously in their solutions. Formal tools are beginning to show up in the EMS industry.

An intelligent communication scheme for power protection system
2013 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices, 2013In this paper, we propose an intelligent communication scheme for power protection system. The objective is to improve the reliability of power protection system and make sure protective devices accurately trigger protection schemes when system faults occur.
