Improve the Voltage Level in Hvdc Systems by Using Modular Multilevel Converter
Authors: ,
Abstract: This paper proposed a finest intend scheme of Modular-Multilevel-Converter (MMC) levels for move towering the practical conciliation flanked by the precision and divisional competence. The whole process is standard by a Thevenin-equivalent 133-level MMC model. Firstly the computation scheme of the fundamental limit imitation time step is offered to dependably signify respectively voltage level. Secondly the earlier industrial Improved Analytic Hierarchy Process (IAHP) is assumed toward combine the virtual faults of all the input electrical factors interested in one complete virtual fault on apiece converter level. Thirdly the stable AC and DC ephemeral condition in virtual faults effects of all the forms stabilize and curve integral stand on the standard form. Finally the finest MMC levels take by the drown curves and the give individual weights allowing for the precision and competence. And the competence and potency of the propose scheme is validate by model on MATLAB simulink.
