摘要
Abstract
Based on the widespread use of the VSC-HVDC in the power system,a control algorithm for the broadband and high current quality in VSC-HVDC systems was proposed. The no steady-state error control of the converters′output current,which could track the current instructions in current loop,was realized by the closed loop feedback for the different current frequencies and adaptive feed-forward rectification according to the converters properties and power systems′ conditions. The proposed control algorithm improved the controllability of the output current in VSC-HVDC system effectively,purified the harmonic pollution of the VSC-HVDC system while enhanced the governance capacity of VSC-HVDC for power quality,and increased the quality of electric energy and operational stability. Experimental results verify the effectiveness of the proposed control algorithm.关键词
