·         MENU-DRIVEN GRAPHICAL USER INTERFACE (GUI) PROGRAMS- by Prof.H.Sadat. -The transformer program obtains the transformer equivalent circuit from open-circuit and short-circuit tests. It also finds the transformer performance characteristics using the transformer parameters. In the induction motor program the parameters of the equivalent circuit can be entered on the circuit diagram. The program draws the Thevenin's equivalent circuit. Performance characteristics are then obtained for the specified slip and the torque slip curve is plotted on the screen. The analysis can be repeated for different slips. A GUI program deals with the design of a first-order controller in the forward path of a closed-loop control system. This GUI program designs the following controllers: Proportional, phase-lag, phase-lead, PD,PI, and PID controllers. To run the controller design program at the MATLABprompt type>> rldesigngui

·         MATPOWER at .

for a Matlab-based OPF that works for small systems.One of the developers of MATPOWER is Ray Zimmerman

Electrotek has released this updated version of TOP 2000. You can download this program free of charge at: the above hyperlink. The release notes for this version are included below. The program is free and supports most versions of transient analysis programs .

Release Notes: Version TOP2000 V 5.00.01 .These notes describe new features in TOP2000 v5. They also discuss the TOP interface with PASS and SuperHarm.v5.00.01=======

1 - Binary calculator operations now work properly when the two stack objects have incompatible time (or X) values.

2 - New Stack/Expression menu command to create stack objects from typed in expressions. See help file for examples.

3 - Waveform sampling operation in the calculator

4 - New options in the Preferences dialog

a - background (CBEMA, ITIC, etc.)

curve for magnitude-duration plots

b - option for null data gap handling in

trend plots, similar to PQWeb 2.2

c - toggle between seconds and date/time stamps in exported trend CSV files

5 - Support for 3D magnitude-duration histograms downloaded from PQWeb.

6 - Plots a vertical line at the trigger time for stack objects loaded from PQDIF files.

7 - Exports PQDIF files.

8 - Exports a config file for use with the Text-to-PQDIF utility.

9 - Option to auto-generate RMS traces from transient waveforms in the Text-to-PQDIF utility output.

10 - All of the file loading dialog list boxes now follow the standard Windows extended selection mechanism, with Ctrl-Click and Shift-Click.

11 - More combinations of stack object types with calculator operations are allowed.

12 - Revised table column names for time and frequency domain data points, when the first object is not WAVE, SCAN, or SPEC.

SuperHarm Integration

You must run TOP2000 manually one time before it will launch from the SuperHarm or SuperTran toolbar.

PASS Integration

To use TOP2000 with PASS 3.2, use the Edit/ Preferences menu command in PASS, then click the Paths button. For the path to TOP, enter the installed location of top32.exe, for example:


Note that you must use the ~ contractions for long path names with embedded blanks, because PASS is a 16-bit program. The example shown above is the default location for installing TOP2000, but on your machine, the proper shortcut entered into the PASS dialog may include electr~2 rather than electr~1.

If you copy-and-paste more than one graph from PASS, the TOP2000 software will superimpose all voltages on one graph, all currents on another graph, and any other data (eg., temperature)on separate graphs.

As a side effect of PASS integration, TOP2000 will not launch if the older 16-bit version of TOP is running. This is because TOP2000 must use the same window class name, so that PASS can find a running copy of TOP2000.

Data Conversion Utilities

=========================A data conversion utility for Dranetz 656A, 657,

and 658 instruments has been copied to the TOP application directory. This program, ascii65x.exe, should be run from a DOS prompt.

Another data conversion utility for PQDIF files is installed with TOP2000. This converts comma- delimited text files, in a tabular layout, to PQDIF.

Support and Updates

===================You may obtain free updates to TOP, including

sample files and a PDF version of the manual, from

A Unified        Approach to Assessment and Control

Publishers: Kluwer Academic Publishers,2000

Transient Stability of Power Systems is a monograph devoted to a hybrid-direct temporal method called SIME (for Single Machine Equivalent). SIME processes temporal information about the multimachine system dynamics to assess and control any type of transient instabilities under any type and model of power systems. Two approaches may be distinguished depending upon the source of information used: "Preventive SIME" which relies on a time-domain program to simulate anticipated contingencies, and "Emergency SIME" which uses real-time measurements. Both approaches rely on the same principles and basic software, which yields a comprehensive and unified approach to TSA&C. The design of near optimal control techniques is a major asset of this software. This book provides extensive illustrations on a variety of power systems ranging from a simple 3-machine test system to real-world power systems comprising up to 627 generators and 4112 busses. TRANSIENT STABILITY OF POWER SYSTEMS will be especially helpful to researchers, utility engineers, and software designers and developers who are developing various types of transient stability software packages.

A new book in the IEE Power Series:

Embedded Generation

by N Jenkins, R Allan, P Crossley, D Kirschen and G Strbac

Published by the Institution of Electrical Engineers

The use of combined Heat and Power plants and renewable energy sources reduces the amount of greenhouse gases released into the atmosphere and helps alleviate the consequent climate change. The policies of many government suggest that the proportion of electrical energy produced by these sources will increase dramatically over the next two decades. Unlike traditional generating units, these new types of power plant are usually "embedded" in the distribution system or "dispersed" around the network. As a result, conventional design and operating practices are no longer applicable; for example, power protection principles have to be revised and complex economic questions  need to be resolved.

This book, intended for both students and practising engineers, addresses all the issues pertinent to the implementation of embedded generation. Much of the material was originally developed for the UMIST MSc/CPD course in Electrical Power Engineering so there is a strong tutorial element. However, since this topic is evolving very rapidly, the authors also discuss the technical and commercial consequences of the very high penetrations of embedded generation that are to be expected in the years ahead. The authors work together in UMIST's Electrical Energy and Power Systems Group.

This website illustrates how the smart grid operates and the standards needed for each component.

The framework for the grid is divided into seven domains: transmission, bulk generation, distribution,

customers, operations, markets, and service providers.




The site is developed by the Advanced Research Institute of Virginia Tech and holds information related to

 smart-grid technologies, standards, rules and regulations, case studies, public awareness and education.

The clearing house is meant to serve as a decision-support tool for state and federal regulators.

Cutting-edge information technology has been used in Smart Grid project, in the first Smart City project in US.

The Smartness is implemented based on TIBCO's Business Events product. The YouTube video explains the approach in Layman's term.

CEP (Complex Event Processing) is a new computer science area, pioneered by Prof David Luckham.

His book 'The Power of Events: An Introduction to Complex Event Processing in Distributed Enterprise Systems" is of  interest on this subject.
