摘要

准确快速计算模块化多电平换流器（MMC）功率器件的结温波动是进行寿命预测和可靠性研究的关键。在长时间的任务剖面下,基频结温波动对MMC功率模块寿命预测的影响不容忽视。由于MMC桥臂电流的直流偏置特性,使得功率模块内部具有热不平衡特征。提出一种考虑热不平衡特征的MMC功率模块寿命预测方法。首先,分析MMC子模块功率器件的热不平衡特征,提出考虑电热耦合的功率器件低频热循环提取方法,考虑器件损耗热不平衡特征,提出基频结温波动的快速迭代求解方法;然后,利用Bayerer模型和Miner理论所建立的热循环与器件损伤之间的联系,实现MMC系统功率模块的寿命预测。最后,利用算例对所提方法进行验证和分析。

Abstract

Accurate and rapid calculation of the junction temperature fluctuations of modular multilevel converter （MMC） power devices accurately and quickly is the key to lifetime estimation and reliability studies. The impact of fundamental frequency junction temperature fluctuations on MMC power module lifetime estimation cannot be ignored under a long-time mission profile. Due to the DC bias characteristics of the MMC bridge arm current, the power module has thermal imbalance characteristics inside, and this paper proposes a lifetime estimation method of MMC power module considering the thermal imbalance characteristics. Firstly, the thermal imbalance characteristics of the MMC sub-module power devices are analyzed. A low-frequency thermal cycle extraction method for power devices considering electrothermal coupling is proposed, and a fast-iterative solution method for the fundamental frequency junction temperature fluctuation is proposed considering the device loss thermal imbalance characteristics. Then, the link between thermal cycling and device damage established by Bayerer’s model and Miner’s theory is used to realize the lifetime estimation of power modules of MMC systems. Finally, the proposed method is validated and analyzed using an example.
