A Decoupled Control Strategy of Modular Multilevel Matrix Converter for Fractional Frequency Transmission System - 2017 PROJECT TITLE :A Decoupled Control Strategy of Modular Multilevel Matrix Converter for Fractional Frequency Transmission System - 2017ABSTRACT:Fractional frequency transmission system (FFTS), additionally called low-frequency ac transmission system, could be a promising resolution to offshore wind power integration. The ac/ac converter is the foremost important equipment in FFTS. The modular multilevel matrix converter (M3C) is widely considered the subsequent-generation ac/ac converter, however its advanced management remains a downside. A completely unique management strategy is proposed featuring its decoupling algorithm during this paper. Completely different from previous research, the proposed current control regulates current elements of different frequencies separately in star-figure subconverters beneath their synchronous rotating frames (SRFs), where the present is reworked to dq-axis dc signals for a higher performance. A completely unique algorithm named “cross-SRF decoupling algorithm” is proposed to overcome the tight coupling between the circulating currents of 2 completely different frequencies. The effectiveness of the proposed management strategy has been verified by the simulation results obtained from a 110 kV, four hundred MW M3C system implemented in MATLAB /Simulink.
