Power system stability enhancement in two machine system by using fuel cell as STATCOM (static synchronous compensator)

Abstract

In this paper describes fuel cell functioning is a STATCOM to enhance the power system stability during various symmetrical and asymmetrical fault conditions. Nowadays our power utility confronting plenty of issues in retaining the stability of the system. Install the flexible alternating current transmission system (FACTS) compensator gives to be better results for this. But the expenses of compensating system extra payload to the consumers. For this reason a novel approach using fuel cell (FC) is a supply of compensation system was presented in this paper. Fuel cell (FC) was designed as a STATCOM – as a FACTS device. The potentiality of the FC STATCOM to improving transient stability of two machine system after a fault occurrence. In this paper fuzzy logic controller is a main controller was modeled to enhance the power system stability of two machine systems. Fuzzy logic controllers give the trigger pulse to improve the stability after the various fault occurrences. Proposed compensators are carried out in MATLAB simulink tool boxes. The design of with and without compensators was integrated in two machine power system and compared the results with traditional FCSTATCOM device. Various types of asymmetrical and symmetrical faults created in the proposed transmission line system. During the fault more oscillations occurred. After connecting the FC STATCOM oscillation level was reduced. Finally concluded that the results are found to be satisfactory in this proposed fuzzy logic based FC STATCOM compared with conventional FCSTATCOM.
