Loss-of-Field Protection Relay Coordination for Synchronous Generator and Motor Unit Based on Transient Stability

Impedance-Based Out-of-Step Protection of Generator in the Presence of STATCOM

This paper presents a novel impedance-based approach for out-of-step (OOS) protection of a synchronous generator. The most popular and commonly used approaches for detecting OOS conditions are based on the measurement of positive sequence impedance at relay location. However, FACTS devices change the measured impedance value and thus disrupt the performance of impedance-based relay function. In...

SNR Maximization at CSI Aware AF Relay

This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

Digital Communications for Relay Protection

Electric utilities are expanding communications infrastructure due to increased need for information. Due to performance, price, and technological advances, digital communication systems are frequently chosen as this multiple user data network. This two-part paper describes the application of digital communication in power system protection. Part 1 describes the digital communications architect...

Comparison of Several Ramp Generator Designs For Column-Parallel Single Slope ADCs

Many CMOS image sensors now use columnparallel readout structure with single slope ADCs. Ramp generator in the ADCs is a critical building block since the performance of the ADCs depends a lot on the accuracy of the ramp signal. In this paper, we present several ramp generator architectures and compare their performance in terms of resolution, area, noise and reliability.
