Computer software that makes a computer act like an expert!

As the demand for power increases, the existing power grids are being more frequently loaded nearly to capacity. As a result, system operators must rapidly respond to sudden or unexpected changes in the systems operating configuration - for example, wind or lightning suddenly damaging power lines taking them out of service. When contingencies occur, operators must rapidly assess and reconfigure systems if a normal operating state is to be maintained. (To learn about operating states see the Power Flow 2 section).

Because rapid assessment is becoming increasingly important, expert systems have been and are being developed, to assist operators in making decisions regarding security assessment. When sudden changes occur there may not be sufficient time for operators to run numerous power flow scenarios (see Power Flow 1 and Power Flow 2). This is where an expert system can be very helpful.

An expert system is a computer system that can behave like an expert. In this case, the system will behave like a power systems expert. In the event of a failure or sudden change, the expert system can rapidly assess the power systems operating condition and provide the operators with a weighted list that indicates which power lines in a network are most critically loaded and which are least critically loaded. This greatly reduces the operators work load and can vastly improve response time. The end result is improved system reliability.

Below is the latest version of SEEKS and some associated files.

SEEKS - SEcurity 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 file called "seeks" and download all of the files into this new directory. SEEKS is still under development so new version 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.

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