Development of a reconfigurable and data-parallel architecture for real-time digital simulation of large-scale electric power systems

电网正面临着巨大的挑战，需要先进的实时仿真技术来理解和解决。现代电力系统是不断从一种运行状态向另一种运行状态演化的大型非线性结构。仿真是电力系统规划、设计、运行和控制的重要组成部分，是保证向用户提供安全、可靠和高质量电力的重要手段。现代实时数字模拟器除了能够高速模拟复杂的计算模型外，还能够通过高分辨率的输入输出接口与外部硬件进行即时通信。因此，保护继电器或数字控制器可以在硬件在环（HIL）配置中连接到实时模拟器并在安装到电力系统之前进行充分测试。最近在并行处理技术方面取得了重大进展，特别是与

The electric power grid is facing momentous challenges that require advanced real-time simulation technologies to understand and solve. Modern electrical power systems are large-scale nonlinear structures that are constantly evolving from one operating state to another. Simulation is an integral part of power system planning, design, operation, and control, to ensure the safety, reliability, and high quality of electrical power supplied to consumers. Besides simulating a complex computational model at high speed, modern real-time digital simulators are capable of instantaneous communication with external hardware through high resolution input-output interfaces. Thus a protective relay or a digital controller can be connected to a real-time simulator in a hardware-in-the-loop (HIL) configuration and fully tested before being installed in the power system. Significant advances have been made recently in parallel processing technologies related, in particular, to
