Experience With a Standard Protocol in Substation Automation Projects

By Michael Shulim, CEO, ReLab Software LLC, August, 01, 2008 - This article is based on real experience with IEC-61850 stack implementation. It summarizes the development process of the IEC-61850 OPC Server and explains the difficulties in that process. It explains the technical reasons why so few good software implementations of the IEC-61850 stack and particularly IEC-61850 OPC exist today. There may be other business, political or sociological reasons why this happens. The discussion is limited only to technical areas. The author hopes that this technical experience will help others to plan and implement IEC-61850, to properly evaluate the required effort and to avoid possible pitfalls.  more...

Enterprise Agility -- Managing Risk with Agility

By Rick Dove, Chairman, Paradigm Shift International, April, 12, 2005 - Public Service Company of New Mexico (PNM), a medium sized electric and gas merchant utility, provides an excellent case study of agility in response able business processes. This case study focuses on the application of agility-enabling principles, and the benefits these principles generate. These same principles can be applied to the design of any enterprise strategy, business process, or system design. The value of the case study is its demonstration of how agility in anything is achieved, and should be viewed with an eye for generalization to other processes that need response-ability. Chris Hickman, executive director of engineering and technology, and Gene Wolf, principal engineer, were kind enough to spend hours reviewing this case.  more...

Substation automation: IED integration and availability of information

By Jim McDonald, Senior Principal Consultant, KEMA, July, 24, 2003 - Electric utility deregulation, economic pressures forcing downsizing, and the marketplace pressures of potential takeovers have forced utilities to examine their operational and organizational practices. Utilities are realizing that they must shift their focus to customer service. Customer service requirements all point to one key element: information, i.e., the right amount of information to the right person or computer within the right amount of time. The flow of information requires data communication over extended networks of systems and users. In fact, utilities are becoming among the largest users of data and are the largest users of real-time information.  more...
