Introducing Power System Event Report Data Into Plant Historian Systems

摘要

Energy usage is a significant product cost component for many industrial and manufacturing facilities. Managing the availability, delivery, reliability, and allocation of energy resources has historically been a major challenge for plant and facility managers. As an example, the electrical transmission and distribution networks in many mills rival those of most municipalities in regard to size and complexity but traditionally have included only limited integration or online monitoring within the manufacturing control system. This limitation existed, at least in part, because the protective relays and meters were electromechanical vintage and did not include communications or recording capabilities. Either due to equipment end-of-life or facility improvement projects, many upgraded plant substations now include modern intelligent electronic devices (IEDs), which not only perform much better than their predecessors in their primary function but also enable significant improvements for communications and integration. Convenient and flexible methods exist for users to view and benefit from the information produced by these IEDs. Other papers describe how this is accomplished.
