本文提出了一种风力发电变流器电力电子模块（PEMs）分布式热监测方案。该传感系统基于嵌入PEM基板的非导电和抗电磁干扰光纤布拉格光栅（FBG）传感技术。首先介绍了该方案的设计和实现特点。然后将该方案应用于在逆变器桥内运行的商业PEM，该桥还配备了使用多点热电偶（TC）传感器套件的传统分布式热监测系统。进行了一系列测试，以评估FBG分布式热监测系统的性能，并将其与代表实际风力涡轮机中PEM运行的稳态和瞬态运行条件下的TC测量相关联。实验结果表明，所提出的光纤光栅监测系统可以为风电电源模块分布式热传感方案的建立提供实际的操作改进。
This paper reports a distributed thermal monitoring scheme for power electronic modules (PEMs) in wind turbine converters. The sensing system is based on utilizing electrically non-conductive and electromagnetic interference immune fiber Bragg Grating (FBG) sensing technology embedded in the PEM baseplate. The design and implementation features of the proposed scheme are presented first. The scheme is then applied in a commercial PEM operating within an inverter bridge, equipped also with a conventional distributed thermal monitoring system using a multiple point thermo-couple (TC) sensor suite. A range of tests are performed to evaluate the performance of the FBG distributed thermal monitoring system and correlate it to TC measurements under steady-state and transient operating conditions representative of PEM operation in an actual wind turbine application. It is shown that the proposed FBG monitoring system can offer practical operational improvements in establishment of distributed thermal sensing schemes for wind turbine PEM.
