摘要 柔性直流换流阀的可靠运行很大程度上取决于阀子模块内的绝缘栅双极型晶体管(IGBT)器件,除了子模块的冗余设计,实时检测子模块内IGBT的状态同样具有重大意义。现行的检测手段难以实现IGBT正常状态、老化状态、不同故障状态的快速诊断以及实时同步检测。因此,该文提出一种基于脉冲耦合响应的状态检测方法,该方法通过向集射极注入短时高压脉冲激励,分析脉冲下IGBT等效二端口网络的输出响应,可以在1μs内快速检测IGBT运行状态,并在故障情况下识别故障类型。最后通过实验结果与Pspice仿真结果的对比,验证了所提方法的可行性与正确性。

Abstract:The reliable operation of the voltage source converter based high voltage direct current transmission (VSC-HVDC) valve depends mostly on inusated gate bipolar transistors (IGBT) in its submodules. Apart from the redundancy design of submodules, a real-time IGBTs’ status detecting also makes a great sense to the reliability improvement. Current methods are not able to realize the fast and real-time synchronous detection of IGBTs’ normal status, ageing procedure as well as different fault status. As a result, this paper carries out a conditioning detecting method based on pulse coupling response where a short high voltage pulse excitation is fed between the collector and the emitter. By analysing the output response of the equivalent two port network, IGBT’s status can be quickly detected within 1μs, as well as its fault type if it’s faulty. In the end, an experiment is carried out. Comparison between experiment results and Pspice simulation results validates the feasibility and correctness of proposed method.
