Advanced condition monitoring of electric machinery

汽车、航空航天、海上风能和制造行业正在寻找性能大大提高的信封电机和驱动装置，以支持市场电气化的雄心勃勃的计划。除了改进的设计外，所需解决方案的很大一部分将通过应用改进的传感、监测和控制管理技术来实现--在变速机器/驱动系统中，这些技术可以更好地了解工作点接近设计极限的情况，并为适当的工作点管理开发先进的例程，以提供更高的性能。为了实现这些，需要大大改进对关键运行参数的监测。本项目将通过探索诊断数据分析的新模式，着眼于改善电机状态监测技术的现状，重点是在暂态运行条件下进行诊断。该项目将开发一种能够进行故障仿真的先进型号的永磁电机驱动器，并将其用于开发和提取暂态运行状态诊断技术的研究。还将设计一个测试系统用于实验研究和模型验证。研究主要与EPSRC电机和驱动器/电磁产品组合保持一致。

The automotive, aerospace, offshore wind and manufacturing sectors are looking for much improved performance envelope electrical machines and drives to underpin ambitions plans for market electrification. In addition to improved design, a large part of the required solution will be enabled by the application of improved sensing, monitoring and control management techniques - in variable speed machine/drive systems these could facilitate a much improved understanding of the vicinity of operating points to design limits, and development of advanced routines for appropriate operating point management to deliver increased performance. To achieve these greatly improved monitoring of key operational parameters is required.This project will look at improving the current state of condition monitoring techniques for electric machines with a focus on diagnosis in transient operating conditions, through exploring new modes of diagnostic data analysis. The project will develop an advanced model of a permanent magnet motor drive capable of fault emulation and utilize it for research on development and extraction of diagnostic techniques for transient operating condition. A test system will also be devised to be used for experimental research and model validation.The research aligns primarily with the EPSRC electrical motors and drives/electromagnetics portfolio.
