Modern distributed applications are long-lived, are expected to provide flexible and adaptive data services, and must meet the functionality and scalability challenges posed by dynamically changing user communities in heterogeneous execution environments. The practical implication of these requirements is that static policy and mechanism definitions are unsuitable for the design of modern softw...

Side channel attacks can be effectively addressed at the circuit level by using dynamic differential logic styles. A key problem is to guarantee a balanced capacitive load at the differential outputs of the logic gates. The main contribution to this load is the capacitance associated with the routing between cells. This paper describes a novel design methodology to route a design in which multi...

This paper presents a real-time phase-domain synchronous machine model for generator protection relay testing and its real-time implementation. The model allows full protection scheme validation including split-phase differential and statorground fault protections. Space harmonics are considered through the use of modified winding function theory, which is used to represent arbitrary winding di...

IEC61850 communication standard for digital substation automation creates a new way to think about conventional protection scheme and configuration of substation. The presence of communication link in process bus makes a revolutionary change for future digital substation. This paper discusses briefly about process bus architecture and presents a new approach of thinking in busbar structure to m...

(Received: October 30, 2011; Accepted: December 8, 2011) Abstract: This paper presents a novel technique for transformer differential protection to prevent incorrect operation due to inrush current. The proposed method in this paper is based on time-frequency transform known as the Wavelet transform. The discrete Wavelet transform is used for analysis the differential current signals in time an...

This article provides a description of protection based on the transformer model. The described by authors does not require calculations and depend operating mode power system. sensitivity ensures detection internal coil short circuits in case transformer. compares proposed algorithm with an improved version differential protection, which is capable fixing most

To date, synchronized phasor measurements have been used mainly for power system model validation, post-event analysis, real-time display, and other similar activities. However, synchrophasors have a greater potential than monitoring and visualization. Synchrophasors will increasingly contribute to the reliable and economical operation of power systems as real-time control and protection scheme...
