Development of a digital data base for power system of Crete, for displaying system's data on geographical maps, using GIS and web tools

摘要

Geographical Information System (GIS) applications are very helpful tools for displaying and analyzing information for several technological fields. The research group of Electrical Power System Lab (EPSL) of TEIC is developing a GIS software application for displaying the operational conditions of the power system of Crete, presenting also critical information and statistical data for system's characteristics. This job is a part of a project which is co-funded by the European Social Fund and Greek National Resources, "EPEAEK II - ARXIMIDES". This tool is intended to help training of engineers in 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. All data used are derived from a database developed by EPSL. This database includes electrical and operational characteristics such as generating plant, substation, transformers, transmission-distribution lines, cables, wind parks, substation's load and unit's power production recordings etc. Digitalized maps of Crete Island use this data and display them optionally according to user's demand or choice. So, an authorized user can decide which data will be displayed 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 runs on a server of EPSL, ehich can serve distant users after authorization procedure. That distance user could be a trainee in his desk, o am engineer, or a researcher in the lab. One of the services that this application provide is the load flow calculation on a specific part of the system, or for a specific scenario of system's operation.
