Intelligent decision support for protection scheme design associated with electrical transmission systems

This paper focuses on collaborative research activities conducted with two major UK utilities, describing the development of a web-based, Design Engineering Knowledge Application System (DEKAS). This system offers automatic intelligent decision support to engineers responsible for the design and application of protection schemes associated with EHV transmission power systems. A web-based environment is promoted as the most effective medium for company-wide dissemination of the information and, knowledge captured within DEKAS. The paper also describes the integration of DEKAS with existing company data repositories in order to provide a single storage and retrieval mechanism for all pertinent information/documentation. Following the identification of ´what´, ´where´ and ´when´ information and data are utilised within the overall protection design process, the paper then concentrates on ´how´ better use can be made of existing engineering resources, through the development of an intelligent decision support facility, utilising case-base reasoning (CBR) techniques
