Improvement using frequency relays compared to dynamic and static relays in frequency instability

Optimal Setting Sor Under Frequency Load Shedding Relays Using Mixed Integer Linear Programming

After occurrence of some disturbances in power system that causes the sever imbalance between generation power and electrical load, the power system frequency begins to decrease. To prevent power system frequency instability and stop the frequency decay below the power system allowable frequency limitation, load shedding schemes should be utilized by applying under frequency load shedding relay...

Dynamic Base Station Energy Saving with Relays

Using Mobile Relays in Multi-Robot Exploration∗

Many robotics tasks require autonomous exploration by teams of robots. In difficult or large environments, communication drop-out complicates this task. Several approaches exist that aim to keep the team connected, but even so there is an inherent limit to the range that can be explored. In this paper we describe and examine Role-Based Exploration, an approach that uses mobile relays to ferry i...

Higher-order thalamic relays burst more than first-order relays.

There is a strong correlation between the behavior of an animal and the firing mode (burst or tonic) of thalamic relay neurons. Certain differences between first- and higher-order thalamic relays (which relay peripheral information to the cortex versus information from one cortical area to another, respectively) suggest that more bursting might occur in the higher-order relays. Accordingly, we ...

Modeling, Developing and Testing Protective Relays using MATLAB, Programmable Relays and Digital Simulators

This paper discusses application of MATLAB, programmable relays and digital simulators in modeling, developing and testing of protective relays. First, the issue of modeling of protective relays is addressed. The new MATLAB-based software capable of modeling digital relays by providing detailed models of the common components of contemporary digital relays is presented. Second, application of p...
