“…The fuzzy logic technique is a type of logic system; it is a critical technique and importance due to a fuzzy method for the system dialectic under confusion and illustrates in unfaithful way near that for human thought. This technique quite varies from Boolean logic and classic logic method; these ways suppose the exact variables in true or false, while fuzzy logic technique is a functional method for recognition and prepare an accurate adjustment that understands a valuation or approximate answer for a problem depending on the store of approximate information, not complete or unreliable [20], [21].…”

The three-phase power transformer in the transmission or distribution substations represents one of the essential devices on electric power networks. Losing this devise cause a disconnection of the power utility to a large number of electrical loads. The robust protection system must be designed to protect the device during abnormal operations. A complete protection system for a poly-phase power transformer for one of the Karbala transmission networks (East Karbala substation) is modeled and simulated, adopting a fuzzy logic protective relaying using MATLAB/SIMULINK environment. This study discusses fuzzy logic-based relaying for a power transformer safety, as well as internal faults that are clearly identified. Two principles of operation are used to protect the transformer; differential relay and overcurrent relay. The differential relay is proposed as the unit protection, while the overcurrent is backup protection. The proposed fuzzy logic controller (FLC) is used to detect abnormal operation; it is also modeled to organize the operation between unit and backup protection. The numerical results clarify that the proposed model can perform fast, rigorous, and authoritative protection for the transformer. Also, modeling of the protection mode decreases the complexity of designing various subsystem and combining them in one controller.

“…In 2017, Deshmukh et al [11] implemented a differential relay to protect the transformer using fuzzy logic to distinguish between fault state and normal states using MATLAB software by selecting an appropriate slope for the differential protection of 25% .The practical part was implemented using two current transducers and a microcontroller from type dsPIC33E, operating as a part of the fuzzy logic controller. The result did not base on IEEE standardized; also, the researcher did not perform all the tests on the transformer.…”

The power systems are exposed to many abnormal conditions, so an advanced protection system must be provided to stand up to these challenges. Protection devices evolved continuously with the development of power systems. The accuracy, high response, reliability, and speed of fault detection are required in the operating mode of multi-function protective relays. A Multifunction Relay has been designed and implemented, which consists of three types of relays: over current relay OCR, over/under voltage relay OVR/UVR, and differential relay DFR. The relays OCR, OVR/UVR, and DFR are designed according to the standards IEC 60255, IEEE 1159, and IEEE C37.91, respectively, based on Arduino MEGA. The multi-function relay was implemented to work on a single phase. The setting of the multi-function relay configuration done using a new design based on the MATLAB GUI environment. Furthermore, the results obtained after each test appear on it and LCD screen. The multi-function relay which is designed can work as (OCR, OVR/UVR, DFR) in the case of a single-phase source. The experiential results show that the proposed multi-function relay is accurate, fast response, reliable, selective, good performance, low cost, and sensitivity when used to protect the power system equipment under different operating conditions.
