子模块混合型LCC-MMC混合直流输电系统的启动控制策略
Start-up control strategies for the cell-hybrid LCC-MMC hybrid HVDC system
摘要
Abstract
In order to fully exert the advantages of LCC and MMC and enable the MMC to have DC fault ride through capability, this paper researches a new LCC-MMC hybrid HVDC system. The system uses traditional LCC in the rectifier side and cell-hybrid MMC in the inverter side. The MMC consists of half-bridge sub-module, full-bridge sub-module and clamp-double sub-module, and has the function of over modulation working and DC fault pass through. It emphatically analyzes the start-up process of the hybrid HVDC system, and then offers the start-up control strategies of the LCC and VSC. Finally, the experimental verification on the built 24 kW hybrid HVDC system indicates that this start-up strategies is feasible and available.关键词
