2016 Corporate Social Responsibility Report

EPRI completed a full corporate social responsibility assessment in 2015 culminating in release of its first Corporate Social Responsibility report. The report (and companion video) provides a comprehensive look at EPRI's social responsibility culture and actions around four focus areas: community, employees, operations, and research.

Abstract

Understanding the condition of its assets is one of the most crucial factors in a utility’s ability to effectively manage its asset fleet. Many sources of data contribute to the determination of asset health, and one of most important is the growing number of intelligent electronic devices (IEDs) being deployed in the field. The challenge becomes how to effectively organize and share this field data with the enterprise analytic applications capable of turning data into asset health insight.

There are three standards published by the International Electrotechnical Commission (IEC) that collectively address this challenge: IEC 61850, IEC 61970, and IEC 61968. Together they provide data models that can organize IED-provided field data into a form that can be used by asset-focused applications. Each standard has its role: IEC 61850 provides data models that structure field data; IEC 61970 supplies models of the grid, including field data, that are used as inputs to network analysis; and IEC 61968 models assets, whose operating environment and condition are informed by both grid position and data from the field. When harmonized and taken together, the three IEC standards have the potential to provide a powerful field-to-enterprise approach to managing the field data critical to gaining insight into the condition of utility assets.

This report examines each standard’s perspective on grid resources and the measurements associated with the grid resources, explores each standard’s data modeling approach, and reviews each standard’s supporting data models. Harmonizing the touchpoints between standards is crucial to realizing the field-to-enterprise data sharing vision. The report overviews the ongoing work of the IEC Common Information Model (CIM)/61850 Harmonization Task Force and the CIM users group (CIMug) Asset Health Focus Community. These two organizations are focused on effectively bridging the distance between standards. The report examines in detail several areas of their work that are providing critical support to the use of field data for asset analytics.

The quality of the IEC standard data models and the progress made to date in their harmonization provide a solid basis for envisioning how a field-to-enterprise asset health data sharing solution could work in the electric utility industry.
