Abstract This paper presents a fuzzy inference system and microcontroller-based protection scheme for a combined underground (UG) cable and overhead (OH) transmission line system. The scheme detects, classifies, and locates the fault occurring either in an UG cable or OH transmission line network. Furthermore, the scheme identifies the faulty section. An existing Indian power network i.e., real power system network of C.G. state, consisting of 132 kV, 50 Hz power transmission network connecting Doma substation 220/132 kV to the 132/33 kV Gas Insulated Substation Rawanbhata through combined transmission network is considered. This real power transmission network is simulated by using MATLAB/Simulink software. In this paper, the hardware implementation is also carried out using an open-source hardware, Arduino, which consists of an Atmel 8-bit AVR microcontroller. Both the simulation and hardware results validate that the proposed scheme is accurately detecting, classifying, and locating the fault in less than a half cycle time. Moreover, the percentage error in determining the location of a fault is less than 0.7%.

1 Introduction The usage of hybrid transmission lines is considered as one of the emerging solutions to the ever-increasing demand of the power supply in the modern era due to the superiority of underground (UG) cable over its counter-part, that is, the overhead (OH) transmission line, as the cable is easier to be laid underground in a densely populated area, or inside a water body. The UG cables can also be incorporated with the power generating renewable sources to serve the purpose of transmitting power supply to some remote places. But, whether the transmission system is an OH line or an * Anamika Yadav [email protected] Valabhoju Ashok [email protected] Mohammad Pazoki [email protected] 1

UG cable, fault occurrence is a common severe problem with them. In the OH lines, faults may occur due to thunder storms, falling of a tree, insulator failure, lightning etc. while lightning overvoltage, ageing, insulation failures, or external damages are some of the factors which can be held accountable for the faults in the UG cables [1, 2]. Many researches have been carried out to detect and locate the faults in the hybrid transmission systems in various ways, either be it an offline method, such as time-domain reflectometer (TDR) and bridge methods, or an online meth
