“…Thus, with DSS, the new visualization concept is to present the system behaviour to the operator by showing process coherences, high quality indicators and automatically generated control measures. The focal point here is to show the causal chain of system behaviour [15,16,18]. 2 shows the proposed decision support system for the southern grid.…”

Control centers (CC) play a very important role in power system operation. An overall view of the system with information about all existing resources and needs is implemented through SCADA (Supervisory control and data acquisition system) and an EMS (energy management system). As advanced technologies have made their way into the utility environment, the operators are flooded with huge amount of data. The last decade has seen extensive applications of AI techniques, knowledge-based systems, Artificial Neural Networks in this area. This paper focuses on the need for development of an intelligent decision support system to assist the operator in making proper decisions. The requirements for realization of such a system are recognized for the effective operation and energy management of the southern grid in India The application of Petri nets leading to decision support system has been illustrated considering 24 bus system that is a part of southern grid.Index Terms--Decision support system, fault diagnosis, fuzzy logic, knowledge-base system, Petri nets, probabilistic logic.

“…This means that many rule-based expert systems developed to address alarm processing include some method of temporal reasoning. For example, one post-fault analysis system [7] has explicit concepts for events and incidents: SCADA alarms are first grouped into events, then related events are linked to form an incident. The investigation of an incident involves analysing the sequence of events to determine whether secondary analysis of further datasets is required.…”

“…Over two decades of research have produced numerous expert systems [3], [4], [5], [6], [7], and model-based reasoning systems [8], [9], [10], for alarm processing for both transmission and distribution systems. However, the move to more observable distribution networks, which are active rather than passive, leads to a new set of challenges in understanding system behavior, health and performance of distribution automation and active network management schemes on a day-to-day basis.…”

Abstract-With a move to 'smarter' distribution networks through an increase in distribution automation and active network management, the volume of monitoring data available to engineers also increases. It can be onerous to interpret such data to produce meaningful information about the health and performance of automation and control equipment. Moreover, indicators of incipient failure may have to be tracked over several hours or days.This paper discusses some of the data analysis challenges inherent in assessing the health and performance of distribution automation based on available monitoring data. A rule-based expert system approach is proposed to provide decision support for engineers regarding the condition of these components. Implementation of such a system using a complex event processing system shell, to remove the manual task of tracking alarms over a number of days, is discussed.

The proliferation of monitoring equipment on modern electrical power transmission networks is causing an increasing amount of monitoring data to be captured by transmission network operators. Traditional manual data analysis techniques fail to meet the analysis and reporting requirements of the utilities which have chosen to invest in monitoring. The volume of monitoring data, the complexities in analysing multiple related data sources and the preparation of internal reports based on that analysis, render timely manual analysis impractical, if not intractable.In 2006, the authors reported on the first online trials of the protection engineering diagnostics agents (PEDA) system, an automated fault diagnosis system which integrated legacy intelligent systems for the analysis of SCADA and digital fault recorder (DFR) data in order to provide automatic post fault assessment of protection system performance.In this paper the authors revisit the requirements of the TNO where PEDA was trialled. Based on a new formal specification of requirements carried out in 2008, the authors discuss the requirements met by the current version of PEDA and how PEDA could be augmented to meet these new requirements highlighted in this latest analysis of the utilities' requirements.Index Terms-decision support systems, fault diagnosis, intelligent systems, knowledge-based systems, power transmission protection, multi-agent systems.
