碩士 === 國立中正大學 === 電機工程所 === 94 === Arc furnaces used for steel production are a main cause of voltage fluctuations in electrical networks, which may give rise to the flicker effect. Voltage fluctuations, due to ramdom are-length variations during scrap melting. Static-var-compensator(SVC) are installed in plants feeding arc furnaces in order to compensate both voltage fluctuation and voltage distortion.
This thesis discuss simulation and analyze harmonic characteristicd generated by a steel firm, that equipped with arc furnace, high-power ac/dc adjustable speed drives cycloconverters and static var compensator(SVC) and passive harmonic filters. From actual measurements and analyzed and compared with the simulation results obtained by using MATLAB/Simulink and EMTP/ATP. It is shown that simulation results and the actual measurement are in a good agreement. Then install active power filter(APF)and high order passive harmonic at steel firm by simulation. To observe harmonic improvement situation.
The contributions of thesis include (1)Typical steel firm including several harmonic and flicker sources, to simulation and measure harmonic components using software, (2)To compare active power filter and passive harmonic filters harmonic improvement situation when install at steel firm, (3)To compare cost when install active power filter and passive harmonic filters, (4)Building an ac electric arc furnace modle using EMTP which is suitable for time-domain harmonic analysis.
