Lessons Learned Implementing an IEC 61850-based Microgrid Power- Management System

A North American oil refinery recently improved on-site power system reliability by installing a new utility ring-bus substation, a new utility interconnect substation, four new medium voltage distribution switchgear lineups, and separating two on-site 14.9 MVA cogeneration units onto dedicated buses in our management system . The refinery also … [Read more...]

Test & Implementation Framework for IEC 61850-based Microgrid Power Management Systems

Test the Solution  - We carefully planned the FAT to verify secure microgrid power management system operation in normal operation for the design contingencies and under the variety of failure and equipment-outage scenarios identified earlier. Each individual device was power cycled under normal, non-fault conditions. Communication channels were … [Read more...]
