Next generation electromagnetic transient simulation tool for large-scale power systems with detailed equipment models

电力系统是最大的人造地理分布非线性结构，由各种设备组成，如发电机，变压器，输电线路，客户负载，跨越数千公里。电磁暂态仿真（EMT）工具用于分析和解决电力系统中的主要运行和控制问题。大型电力系统的EMT仿真需要大量的计算能力，因此迫切需要并行编程技术。目前可用的EMT仿真工具都设计为在单核cpu上运行，因此无法利用多核cpu和多核图形处理器（gpu）来管理计算负载。当处理单元有足够的硬件内核时，大规模线程计算是可以大大提高EMT计算能力的关键发展之一。该项目的目标是开发一系列创新，以实现GPU和多核CPU硬件架构上的大规模电力系统的并行大线程EMT模拟器。本工作的主要特点是设计和建立各种电力系统和电力电子元件的大线程模型，有限元和时域有限差分模型，高效的数值算法，先进的数据分析和可视化，以及模拟器的验证。项目结果有望证明功能并行大线程EMT模拟器的可行性，该模拟器可以在使用非常详细的系统组件模型的情况下实现大规模系统仿真的计算加速。该项目的主要受益者将是马尼托巴HVDC研究中心（MHRC），该中心可以将开发的创新技术集成到其旗舰EMT模拟工具PSCAD/EMTDC中。在这个项目中训练的经验丰富的高素质工程师团队将有助于EMT模拟技术的不断进步，并可能被证明是MHRC未来有价值的员工。

Electrical power systems are the largest man-made geographically distributed nonlinear structures that arecomposed of a variety of equipment such as generators, transformers, transmission lines, customer loads,spanning thousands of kilometers. Electromagnetic transient simulation (EMT) tools are used analyze andsolve major operational and control problems in power systems. EMT simulation of large-scale power systemsconsumes so much computational power that parallel programming techniques are urgently needed in this area.Currently available EMT simulation tools were designed to run on single-core CPUs, and therefore, cannottake advantage of the multi-core CPUs and many-core graphics processors (GPUs) to manage computationalload. Massive-thread computing is one of the key developments that can increase the EMT computationalcapabilities substantially when the processing unit has enough hardware cores. The aim of this project is todevelop a host of innovations towards implementing a parallel massive-thread EMT simulator for large-scalepower systems on the GPU and multi-core CPU hardware architectures. The main features of this work is todesign and build massive-thread models for various power system and power electronic components, finiteelement and finite difference time domain models, efficient numerical algorithms, advanced data analysis andvisualization, and validation of the simulator.The project results are expected to prove the feasibility of a functional parallel massive-thread EMT simulatorthat can achieve computational speed-up in large-scale system simulation while using very detailed systemcomponent models. The main beneficiary of this project will be Manitoba HVDC Research Centre (MHRC)which can integrate the developed innovations into their flagship EMT simulation tool PSCAD/EMTDC. Theexperienced team of highly qualified engineers trained in this project will contribute to the ongoingadvancement of the EMT simulation technology and may prove to be valuable future employees for MHRC.
