Practical implementation of a parallel massive-thread off-line electromagnetic transient simulator

电力系统是最大的人造分布式非线性结构，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）程序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。目前可用的离线EMT仿真程序设计为在单核cpu上运行，因此不能利用多核cpu和多核图形处理器（gpu）来管理计算负载。当处理单元拥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。该项目的目的是在GPU硬件架构上实现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为各种电力系统组件、数值算法、图形用户界面（GUI）和离线EMT模拟器的验证设计和构建大线程模块。

Electrical power systems are the largest man-made distributed nonlinear structures that are composed of a variety of equipment such as generators, transformers, transmission lines, customer loads, spanning thousands of kilometres. Electromagnetic transient simulation (EMT) programs are used analyse and solve major operational and control problems in power systems. EMT simulation of large-scale power systems consumes so much computational power that parallel programming techniques are urgently needed in this area. Currently available off-line EMT simulation programs were designed to run on single-core CPUs, and therefore, cannot take advantage of the multi-core CPUs and many-core graphics processors (GPUs) to manage computational load. Massive-thread computing is one of the key developments that can increase the EMT computational capabilities substantially when the processing unit has enough hardware cores. The aim of this project is to practically implement a parallel massive-thread EMT simulator for large-scale power systems on the GPU hardware architectures. The main features of this work is to design and build massive-thread modules for various power system components, numerical algorithms, graphical user interface (GUI), and validation of the off-line EMT simulator.
