| This paper proposes an optimal design of single hmed shunt passive filter for the Underground Ramsis Metro Substation (URMS) using Linear Programming technique as a conventional I technique and fuzzy linear programming (F'LP) technique as a modem technique. The optimal I filter parameters are obtained to overcome the harmonics generated in the voltage and current waveforms, due to the non-linear characteristics of the rectifiers, which distort the voltage and currents waveforms at the point of common coupling (PCC). The harmonic levels are analyzed at I I different loading conditions using the Fast Fourier Transform (FFT) on MATLAB optimization i program. The proposed optimal design of harmonic filter is based on minimizing the cost of the 1 filter parameters and its losses. Both techniques are applied on the system under study. From the 1 results, the THD levels of the line cunent and the bus voltage are reduced to be within the standard limits. A comparison between the optimal design filters are carried out using t | ||
