NOVEL CALORIMETER FOR DEVELOPING HIGH-EFFICIENCY PERMANENT-MAGNET MACHINES AND POWER CONVERTERS (NovCHEPM)

能源是国家政策议程上的首要问题之一。能源效率是实现英国政府和国际条约设定的国家目标以减少二氧化碳排放的关键。电机和驱动器是工业和经济的驱动力。这两个领域是EPSRC塑造能力议程确定的少数“增长”领域之一。同样，电力电子被广泛认为是英国的关键和高增长技术之一，因为它在提供低碳技术方面发挥着关键作用。在过去的几十年里，英国在开发高性能功率转换器件方面一直处于国际领先地位，但性能的进一步提高需要精确的验证工具。在纽卡斯尔和英国，我们目前依靠输入输出方法来测试PM机器驱动器和电力电子设备，这被证明缺乏高效率的精度。这种限制阻碍了我们的研究活动，因为许多对英国重要的尖端技术，导致航空航天，汽车和家庭应用的影响，需要高效率的电机和驱动器。到目前为止，我们还不能准确地验证我们的数值模型，在这些模型中，预测和实现非常低的损失可以决定一个概念的成功和失败。通常，不确定性往往大于系统效率的2%，这可能大于系统中的总预测损耗。因此，迫切需要一种高精度的设备来测量电机和功率转换器中的功率损耗，精度为1- 2 W，目前世界上任何地方都没有。该提案通过提出一种创新的热量计并使用它检查机器和转换器的功率损耗模型来满足国家和机构的战略需求。为了实现这一目标，我们将汇集我们领先的量热法、PM机器和电力电子方面的专家。一旦完成，该项目将为英国（位于纽卡斯尔）提供高精度和多功能的能力，用于对PM机器和功率转换器的功率损耗和效率进行实验评估，然后对这些设备进行相应的改进。这项拟议的工作将在今后10至50年内产生长期影响。它将推动精确功率测量的边界，使未来涉及高效电机和PE设备的关键新兴产业的发展成为可能。从这项工作中开发的技术将有可能应用于许多应用，并将有助于英国在高性能电气驱动器，如飞机，电动汽车，可再生能源和国内产品的竞争力。

Energy is one of the major issues at the top of the national policy agenda. Energy Efficiency is key to meeting the national targets set by the UK government and by international treaty to reduce CO2 emissions. Electrical Motors and Drives are the driving force in industry and economy. The two areas are amongst the small number of "grow" areas identified by EPSRC's shaping capability agenda. Similarly, Power Electronics is widely recognised as one of the UK's key and high-growth technologies owing to its pivotal role in delivering low-carbon technologies. For the last several decades, the UK has been leading the way internationally in developing high performance power conversion devices but further improvement in performance calls for accurate validation tools. At Newcastle as well as in the UK, we presently rely on input-output methods to test PM machine drives and power electronics, which proved to lack precision for highly efficient ones. This limitation hampers our research activities because many cutting-edge technologies of importance to the UK, leading to impact in the aerospace, automotive and domestic applications, require high-efficiency motors and drives. To date we cannot accurately validate our numerical models in which the prediction and achievement of very low losses can make the difference between success and failure of a concept. Typically, uncertainties tend to be greater than 2% of system efficiency which may be more than the total predicted loss in the system. As a result, there is a pressing need for a highly accurate facility to measure power losses in electric machines and power converters to an accuracy of 1-2W, which does not currently exist anywhere in the world.This proposal addresses national and institutional strategic needs by proposing an innovative calorimeter and by examining machines' and converters' power loss models using it. To deliver this we will bring together our leading experts in calorimetry, PM machines and power electronics. Once completed the project will provide the UK (based in Newcastle) with a high-precision and versatile capability for the experimental evaluation of the power losses and efficiency of PM machines and power converters, and then improvements on these devices will follow accordingly. This proposed work will have a long-lasting impact over the next 10-50 years. It will push the boundary forward in accurate power measurement, enabling future development of key emerging industry involving high-efficiency electrical machines and PE devices that would not otherwise happen. The technologies developed from this work will be potentially applied to many applications and will contribute to the UK's competitiveness in high-performance electrical drives such as aircrafts, electric vehicles, renewables and domestic products.
