Fault Identification and Localization in Power System Networks: A Review of Blockchain based Approach

Wokoma, B. A., Dumkhana, L., Ahiakwo, C. O.

Abstract


The need to precisely identify faults and faulted locations in electrical power system is a mandatory requirement that every Power System Operator (PSO) must be able to fulfill in order to ensure the much-needed time-activated stability. Notwithstanding the advancements in power system fault monitoring and relaying, it is still faced with the recurrent challenge of stability due to the same reason for the improvement itself – the “advancement of the technology”. In particular, the current modernization of power systems into the cyberspace has introduced in it a novel set of challenges majorly related to the data acquisition process. Some issues that may occur during remote fault identification and localization, such as corruption of fault data, hijacking of relaying commands and time clock manipulation are common examples faced by a cyber- interconnected power system. In this regard, the emerging field of blockchain technology has been proposed more recently to alleviate these issues and more so safeguard the integrity of the power system. This paper presents an overview of the important power systems field of fault identification and localization and how the blockchain have and/or may be used to further optimize the data monitoring and gathering process. In future, it is expected that researchers in power systems will consider the blockchain approach in addition to other emerging technologies such as IoT.
