附录一:英文原文 A GIS WEB ? APPLICATION FOR POWER SYSTEM OF CRETE J. Syllignakis, C. Adamakis, T.M. Papazoglou The Technological Educational Institute of Crete TEIC, Greece ABSTRACT Geographical Information System GIS applications are very helpful tools for displaying and analyzing informationfor several technological fields. The research group of Electrical Power System Lab EPSL of TEIC is developing aGIS software application for displaying the operational conditions of the power system of Crete, presenting alsocritical information and statistical data for system’s characteristics. This tool is intended to help training of engineersin the Electrical Department of TEIC to simulate and visualize power system operation and characteristics. Besides,this tool is very helpful for a power system engineer in observing the whole system operations and system’s data. Alldata used are derived from a database developed by EPSL. Digitalized maps of Crete Island use this database anddisplay them optionally according to user’s demand or choice. So, an authorized user can decide which data will bedisplayed on the map, and with a simple mouse click on a selected element of the map he can b informed about its characteristics. Furthermore, this application is being uploaded on web. This means that this application runson aserver of EPSL, which can serve distant users after authorization procedure. That distance user could be a trainee inhis desk, or an engineer, or a researcher in the lab. One of the services that application provides is the load flow calculation on a specific part of the system, or for a specific scenario of system’s operation.

The customer’s power energy demand is increasing with high rates. The operation of the whole system is in charge of the Greek PPC public power co
