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

电力系统是由发电机、变压器、输电线路、用户负荷等各种设备组成的跨越数千公里的大型人工分布式非线性结构。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。大规模电力系统电磁暂态仿真计算量大，迫切需要并行编程技术。目前可用的离线EMT仿真程序被设计为在单核CPU上运行，并且因此不能利用多核CPU和众核图形处理器（GPU）来管理计算负载。大规模线程计算是一个关键的发展，可以大大提高EMT的计算能力时，处理单元有足够的硬件内核。本项目的目标是在GPU硬件架构上实现一个并行双线程的大规模电力系统EMT仿真器。这项工作的主要特点是设计和构建各种电力系统组件，数值算法，图形用户界面（GUI），并验证离线EMT模拟器的双线程模块。

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.
