SEEKS - SEecurity Evaluation Knowledge based System - an expert system

INSTRUCTIONS

Simply download the files below. Place all of the files into the same directory. We recommend that you create a directory called "seeks" and download all of the files into this new directory. SEEKS is still under development so new versions will be placed onto this web page as development continues.

SEEKS is currently a rather crude application, but it should run from Windows or NT with no difficulty. Read over the example provided then try running SEEKS. The user interface still needs some work so be patient. Read the example carefully.

Unfortunately, SEEKS and PSAP cannot be downloaded using Netscape. We are working to correct this problem. For now, it is necessary to use Microsoft Explorer to download SEEKS and PSAP.

Download Seeks - Seeks
SEEKS is an expert system which uses operational planning knowledge to provide insight into power system voltage behavior.

Download Seeks input format - seeks_format.txt

Download PSAP - PSAP
Power System Analysis Program (PSAP) is used to solve the power flow.

Download PSAP input format - psap_format.txt

Note that SEEKS and PSAP work together to produce a power flow solution.

Download an Example of how to run through SEEKS/PSAP - EXAMPLE2.txt .
A more detailed runtrough (new_example.doc) is also available along with some built in data.

Download a flowchart of SEEKS/PSAP operation.

Download - Demo2000 - example input file (Power system model) and download a one-line diagram of the system modeled by Demo2000.

To see further examples of the ß effect on PV curves you can download the following Matlab file pvcurve.m into the bin directory of your Matlab program. Simply typing pvcurve at the Matlab prompt will begin the program.

You can also view the following PV equation program that calculates |V₂| for various inputs to the PV equation variables and then computes whether |V₂| is in violation of voltage security. If |V₂| is in violation, the program gives the amount of ß needed for correction of the PV curve, which can then be used in the previously mentioned Matlab program to graph PV curve.

The following is an example "run through" explaining how to input and run a particular system using a combination of the SEEKS and Power Flow programs together: RUNTHROUGH.TXT (We recommend you print this out for a reference while running the programs above)

GAAM - Generalized Alarm Analysis Module - a Logic Based System

GAAM is a software package that integrates a one-line diagram of a power system, a sequential event report (SER), a trip summary and an intelligent alarm analyzer into a single screen.  This package is a convenient tool for simulating faults as well as protection system malfunctions in a power system and analyzing the protection system’s response to the fault.  The IAA can then be used to determine all of the possible locations, types of faults, and protection system malfunctions. 

This program is not available for free distribution.  If you do not have access to GAAM, you will not be able to create new cases.  You can however still use the lesson plan below, which includes three fault scenarios with information generated by GAAM.
