摘要
基于MMC-HVDC(模块化多电平高压直流输电)的阀组电气参数及其运行维护研究对换流站重要设备的选型、设计、制造和试验具有较大的指导作用。本文围绕渝鄂直流背靠背联网工程开展研究,充分考虑了IGBT换流阀的不同稳态运行工况、各种暂态工况、多种异常状态以及设备运行维护等因素,提出了IGBT换流阀内部器件选型原则及其运行维护方案。研究结果为实际工程提供了重要的参考依据。
The electrical parameters and operation and maintenance of the valve based on MMC-HVDC(modular multilevel converter high voltage direct current)are of great guiding role in the selection,design,manufacture and testing of the important equipment of the converter station.In this paper,the research on the DC back-to-back network engineering linking Chongqing and Hubei takes full account of the different steady-state operating conditions,various transient conditions,various abnormal conditions and equipment operation and maintenance.And the principle of internal device selection and operation and maintenance program of IGBT converter valve are put forward.The results provide an important reference for practical engineering.
