摘要
由于分布式电源及电力电子等新型电力技术的不断发展,电力电子技术的不断渗透将成为未来电力系统的发展趋势。鉴于电力电子元件导致的网络拓扑突变以及其自身的非线性特性会对电磁暂态模型和算法提出了新要求,总结传统电力系统电磁暂态耦合算法,并在此基础上分析算法在应用中会遇到的问题和挑战。从电机模型处理和针对电力电子网络的插值方法等几方面介绍电磁暂态仿真的进展,并汇总消除数值振荡的典型算法及针对大电网的几种并行算法。
Due to the continuous development of new electric power technologies including distributed generation and power electronics devices, etc., the continuous penetration of power electronic technology will become the development trend for power system in the future. However, the network topology changes caused by power electronic devices and its nonlinear characteristics may bring new requirements for the electromagnetic transient（EMT） models and algorithms. This project reviews traditional EMT simulation algorithms used in power system, and analyzes the encountered problems and challenges in the application. This paper introduces the development of EMT simulation from the aspects of the electrical machine model processing and the interpolation method for power electronics system network, etc. In addition, this paper also summarizes the typical algorithms for eliminating numerical oscillations. Furthermore, several parallel algorithms for analyzing large power grid are also presented.
