摘要

为充分利用传统高压直流输电（LCC-HVDC）与柔性直流输电（VSC-HVDC）各自的优点

建立了整流侧采用LCC换流站

逆变侧采用VSC换流站的混合直流（hybrid HVDC）输电系统。对直流系统两侧换流站主控制器进行了设计

并针对该系统设计出双侧功率/频率调制的辅助控制器。最后对混合直流输电系统与交流输电线路并行输电和单独的混合直流输电系统进行了仿真与分析

通过仿真验证了当系统受到扰动时所加辅助控制器能提高系统的稳定性。

Abstract

This paper establishes a hybrid HVDC power transmission system which the rectifier side using the LCC converter station while the inverter side using the VSC converter station to make full use of respective advantages of LCC-HVDC and VSC-HVDC. The main controller on both side of converter of DC system is designed

bilateral power/frequency modulation is added to this control system. Finally

the hybrid HVDC system in parallel transmission with AC transmission lines and single hybrid HVDC system are simulated and analyzed

Simulation results show that the auxiliary controller can improve stability of system when system is disturbed.
