Title: Automated Data Retrieval, Analysis and Operational Response Using Substation Intelligent Electronic Devices
Abstract: SUMMARY Availability of a multitude of substation Intelligent Electronic Devices (IEDs) has created a challenge in utilities of how to manage the abundance of data recorded by such devices during various types of events. The paper explores the goals, objectives and deployment aspects of field solutions that are aimed at data retrieval, analysis and decision support for operators. The goals of utilizing IED data are in general driven by the cost benefit in utilizing more data and better information to improve reliability, quality of service, personnel productivity, regulatory compliance, and utilization of assets. The objectives are to develop such solutions through seamless integration with legacy solutions hence assuring continuity of existing and introduction of new practices. Hence the deployment approaches have to be based on interoperability and open platform solutions that assure upgradability, testability and amenability to global standard adoption while meeting the cybersecurity requirements. To illustrate different requirements for data retrieval and analysis, as well as different aspect of the operational uses, several applications are explored: cause-effect analysis of protective relay operation, optimization of fault location calculation, intelligent alarm processing , and utilization of the field data for troubleshooting tests. For each application an example of how the data processing may be implemented is given and improvements criteria are established. To illustrate the best practices this paper starts with discussion of new requirements for such solutions. In all instances the end users have to be identified and their needs have to be clearly articulated through development of well-structured use case scenarios. After the approaches to the deployment specification are discussed, the paper illustrates various implementations undertaken by several utilities. For each case the applications of interest are outlined, specific deployment scenarios are explained, and expected benefits are summarized. Last but not least, interoperability concept based on the Grid Wise Architecture Council's stack (1), an interoperability context-setting framework, is mentioned as it applies to the types of applications discussed in this paper.
