Modern power semiconductor characterization, modelling and loss estimation in EMTP-type simulators

电力系统仿真器是研究和设计电力系统网络的重要而经济的系统，包括在电力分配和利用的背景下。然而，现代模拟器(如PSCAD)中的功率半导体模型仅基于具有导通和断开两级的理想开关，它没有考虑功率半导体在开关过程中的实际和详细的特性。因此，它不能模拟现代电力系统中电力电子变流器的效率和热行为，例如微电网中的可再生能源变流器。在这项工作中，将对与现代电力半导体相关的电力系统仿真方法进行全面的研究，并对仿真结果进行实验验证。在项目结束时，将生产出一个快速、准确、可靠的电力系统仿真器。*该项目将与马尼托巴省高压直流研究中心(该项目的工业合作伙伴)密切合作，并基于他们的电力系统仿真软件产品PSCAD。该研究项目的模拟器将帮助马尼托巴省水电等公用事业公司的工程师对未来电网进行有效和快速的规划、设计和研究。这也将有利于电力电子设备制造商，如太阳能逆变器，评估其产品的效率和功率密度。此外，该项目还将培训1名博士后、1名博士、1名硕士和4名暑期理科学生。这些HQP将学习尖端技术，并将能够在未来为加拿大电力和能源行业做出贡献。

Power system simulators represent an essential and economical system for studying and designing power system networks, including in the context of power distribution and utilization. However, the power semiconductor model in modern simulators, e.g. PSCAD, is only based on an ideal switch with conducting and disconnecting stages, it does not account for the actual and detailed characteristics of power semiconductors during switching. Thus, it cannot simulate the efficiency and thermal behavior of power electronics converters in modern power systems such as the renewable energy converters in Microgrids. In this work, a comprehensive investigation into the methodology of power system simulation associated with modern power semiconductors will be carried out and the simulated results will be experimentally verified. At the end of the project, a quick, accurate and reliable power system simulator will be produced. ** **The project will be in tight collaboration with the Manitoba HVDC research Centre (the industrial partner of the project) and is based on their Power System Simulation software product, PSCAD. The resultant simulator of this research project will assist engineers in Utility Companies, such as Manitoba Hydro, with effective and rapid planning, design and research on future power grids. It will also benefit the manufacturers of power electronics apparatuses, e.g. solar inverters, to evaluate the efficiency and power density of their products. Further, 1 PostDoc, 1 PhD, 1 MSc and 4 summer BSc students will be trained in the project. These HQP will learn cutting-edge technologies and will be able to contribute to the Canadian Power and Energy industry in the future.**********
