Abstract:
本发明公开了一种柔性直流输电模块化多电平换流器子模块IGBT的在线监测方法,包括以下步骤:1)计算模块化多电平换流器桥臂中各IGBT的通态电阻R<sub>CE</sub>;2)将模块化多电平换流器桥臂中各IGBT的通态电阻R<sub>CE</sub>与正常情况下IGBT通态电阻R<sub>CE0</sub>进行对比,计算模块化多电平换流器桥臂中各IGBT通态电阻R<sub>CE</sub>的增大百分比A,再根据模块化多电平换流器桥臂中各IGBT通态电阻R<sub>CE</sub>的增大百分比A评估模块化多电平换流器桥臂中各IGBT的剩余使用寿命及老化程度,完成柔性直流输电模块化多电平换流器子模块IGBT的在线监测,该方法能够实现对监测模块化多电平换流器中IGBT的在线监测。
