Abstract

This paper presents a 1MW, 12-pulse thyristor rectifier with passive filter and DSTATCOM for low voltage, high current industrial dc loads. The considered process act (electrically) as a current controlled, variable voltage load. Moreover the load characteristic varies extensively with number of hours of operation. Variable compensation capabilities are required to provide harmonic and reactive power compensation for such kind of loads. A Distribution Static Compensator (DSTATCOM) is used to provide variable reactive power compensation. Along with it an 11th harmonic passive filter with substantial amount of reactive power support is provided to reduce required rating of DSTATCOM. Design and control of system are carried out such that input power factor remains greater than 0.98 and THD remains below 5%. Simulation results are presented to verify the effectiveness of the system.
