Abstract: Recently, the development of solid state fault current limiters (SSFCL) offers one of the most attractive alternatives to solve the fault current problems. The operation of an SSFCL is based on the natural transition of the superconducting state to normal state by exceeding the critical current of the material. In modern power system, an increase in the growth of electrical energy demand is inevitable resulting in a corresponding increase in the short circuit in the power system. For this, Fault Current Limiter (FCL) became best option to reduce circuit breakers rated capacity and may limit the electromagnetic stress in associated equipment’s. In this paper modelling of solid state fault current limiter (SSFCL) under various fault conditions are carried out. The function of SSFCL in power system is to work as circuit breaking element as well as limiting the fault current to a safe level. SSFCL is considered as the solution to the increment of short circuit level in power system. It is the most economical option compared with any other conventional solution to overcome this matter. Despite, it may limit the fault current, SSFCL offer advantages to the electricity supply industry, technically and economically. The proposed SSFCL is implemented on 11 KV feeders. This paper presents the modelling of solid state fault current limiter (SSFCL) using Matlab Simulink.
