摘要
基于 IGCT的柔性直流输电模块化多电平换流阀(MMC)具有低成本、低损耗、高可靠等潜在优势,在未来陆上大规模新能源送出以及深远海风电并网等应用中具有广阔的前景.在对比集成门极换流晶闸管(IGCT)和绝缘栅型双极晶体管(IGBT)两类功率器件技术性能基础上,介绍了±525 kV/3000 MW柔性直流输电 IGCT-MMC换流阀的产品设计.依据 IEC 62501 标准,完成了 IGCT-MMC 换流阀产品的第三方见证试验.试验结果表明,所研制的IGCT-MMC换流阀产品技术性能符合设计要求.
Abstract
The IGCT-based modular multilevel commutator(MMC)for flexible DC transmission has the potential advantages of low cost,low loss,and high reliability,and has a broad application prospect in future applications such as large-scale new energy power delivery on land and grid-connection of wind power in deep and distant oceans.This paper performs a comparative analysis on the technological performance of two types of power devices,namely,integrated gate commutator thyristor(IGCT),and rim-gate bipolar transistor(IGBT),on the basis of which the product design of±525 kV/3000 MW flexible DC transmission IGCT-MMC converter valve is outlined.According to IEC 62501 standard,the third-party witness test of IGCT-MMC converter valve has been carried out,whose results show the competent technological performance of the developed IGCT-MMC converter valve.
