CIRCUIT-LEVEL COMPARISON OF STATCOM TECHNOLOGIES

摘要

This paper performs a circuit-level evaluation of four modern STATCOM systems, namely True-48-Pulse and Quasi-48-Pulse STATCOMs, Cascade Multilevel and Binary Multilevel Inverters. The comparison is based on a number of factors including circuit topology, harmonic distortion, system losses, GTO quantities, their specific applications and other considerations. The theoretical results are verified by simulation with the use of MATLAB-Simulink Power System Blockset.
