Abstract

A novel series-structure power transmission system connected by LCC-HVDC (line commuted converter based High Voltage Direct Current) and VSC-HVDC (voltage sourced converter based High Voltage Direct Current) is studied. The coordinate supplementary control of LCC-HVDC and VSC-HVDC is proposed to deal with the possible power imbalance at LCC-HVDC sending end. The active power supplementary controller can effectively enhance the active power balance capacity at sending area. Besides, the reactive power supplementary controller of VSC-HVDC is designed to deal with the voltage fluctuation caused by LCC-HVDC active power supplementary control. Simulation results show that the cooperation between active and reactive power supplementary controller effectively enhances the power balance ability of the system.
