DETECTING POWER GRID SYNCHRONIZATION FAILURE ON SENSING OUT OF RANGE FREQUENCY OR VOLTAGE


This paper presents the development of a microcontroller based islanding detection for grid connected inverter with very simple under/over voltage and under/over frequency islanding detection algorithms. The system is based on a microcontroller from Atmel 8051 family. The microcontroller monitors the under/over voltage and under/over frequency from utility grid and the processed value of voltage and frequency for turni ....etc

ppt on detecting spam zombie by monitoring out going messages

ABSTRACT:

Compromised machines are one of the key security threats on the Internet; they are often used to launch various security attacks such as spamming and spreading malware, DDoS, and identity theft. Given that spamming provides a key economic incentive for attackers to recruit the large number of compromised machines, we focus on the detection of the compromised machines in a network that are involved in the spamming activities, commonly known as spam zombies. We develop an e ....etc

Detecting Power Grid Synchronization Failure

Tarun Agarwal
Synchronization means the minimization of difference in voltage, frequency and phase angle between the corresponding phases of the generator output and grid supply. An alternating current generator must be synchronized with the grid prior to connection. It can t deliver the power unless it is running at same frequency as the network. Synchronization must occur before connecting the generator to a grid. Synchronization can be achieved manually or automatically. The purpose of synchr ....etc
