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.
