Implementation of a Purely Digital Substation System Using the IEC 61850 Standard

This paper presents an entirely digital system which has several benefits as compared to the systems that are deployed currently. Utilizing digital capabilities to a much greater extent than is currently used within the power system allows for various improvements upon the current system. One such improvement is the ease of configuring and using the system. Each device can easily alter its functionality through a user interface, and the addition of devices is as easy as plugging it in. Additionally, the burden on the transformer due to the increase in the number of devices is nullified. The information remains accurate and unchanged, even when new devices are added to the system. The entire system conforms to the IEC 61850 standard, such that it adheres to the requirements of the actual power system.
