1-Wide Area Monitoring System (WAMS)

9/12/2013 6

Wide Area Monitoring System (WAMS) is an integral part of power

system operation today.

WAMS Utilizing synchrophasor measurements enable the

monitoring of power systems and provide critical information for

understanding, forecasting, or even controlling the status of power

grid stability in real-time.

In recent years, more and more WAMSs have been built around the

world to meet the growing needs for all kinds of system-stability-

related applications.

A wide-area Frequency Monitoring Network (FNET) utilizing a

family of PMU called FDR was developed by Virginia Tech in

North America.

Wide Area Monitoring System (WAMS)

9/12/2013 7

More than 80 FDRs are installed in the United States and

about 40 installed worldwide.

Egypt is one of the recognized nations in the WAMSs

world

2- Egyptian Wide Area Monitoring System (EWAMS)

9/12/2013 9

EWAMS was constructed through our project “Smart Grid

Frequency Monitoring Network Architecture and Applications”

by installing 10 FDRs in various power stations in Egyptian

Electric power grid.

Egyptian Wide Area Monitoring System (EWAMS)

9/12/2013 10

EWAMS is an Internet based wide area monitoring system

that is constructed using 10 FDRs connected to the VT output in

10 power stations distributed over the Egyptian power grid.

EWAFMS is a power grid situational awareness tool that

collects real-time, Global Positioning System (GPS) time-

stamped measurements with high precision at the transmission

level.

EWAMS made the synchronized frequency, voltage angle,

and voltage magnitude observation of the entire Egyptian power

grid possible with reasonable cost for the first time.

The following figure shows the developed Internet-based

WAMS architecture for the Egyptian power grid.

The developed EWAMS architecture consists of four main

parts:

3-2 FDR Deployment for EWAMS

The locations of the 10 FDRs are decided to provide full

observability of the Egyptian electric power grid for different

monitoring and control applications.
