摘要

以多馈入高压直流输电为例

分析了4种多馈入高压直流输电子系统的拓扑结构

基于PSCAD/EMTDC仿真软件建立了4种不同拓扑结构的多馈入高压直流输电子系统

通过接入受端弱交流系统

研究了4种多馈入子系统的暂态运行特性

仿真结果表明:整流侧为LCC、逆变侧为MMC的LCC-MMC HVDC系统的馈入有效地提高了LCC-HVDC的换相失败免疫力

缩短了故障恢复时间

改善了LCC-HVDC系统的暂态运行特性

提高了系统的供电可靠性。同时降低了VSC-HVDC、H-HVDC的工程造价和开关损耗

也避免了运行时换流器桥臂功率器件的动态均压问题

改善了输出波形的质量

该研究为以后工程应用中多馈入输电结构的选择提供一定的理论指导。

Abstract

The multi-infeed HVDC transmission is taken for an example and four kinds of topological structures ofmulti-infeed HVDC transmission subsystem are analyzed in this paper. Four kinds of multi-infeed HVDC transmis-sion subsystem are established based on PSCAD/EMTDC simulation software

after connected to weak AC system

the transient operating characteristics of four kinds of subsystems are studied. The simulation results show that

LCC-MMC HVDC system

whose rectifier side is LCC and inverter side is MMC

effectively improves the commuta-tion failure immunity of LCC-HVDC

shortens the fault recovery time

and improves the power supply reliability ofthe system. At the same time

LCC-MMC HVDC avoids the problems existing in the operation of H-HVDC andVSC-HVDC

such as high switching loss

high engineering cost and dynamic voltage sharing of power devices forconverter bridge arm. The research is beneficial to select better multi-infeed transmission structures for future engi-neering application.
