摘要

基于移频的交流电网电磁暂态仿真比传统的交流电网电磁暂态仿真更有效。本文提出了一种新的接口，用于SFEMT模型和传统EMT模型的联合仿真。首先推导了SFEMT建模的基本原理。然后，基于旋转不变性技术对信号参数的估计，提出了EMT和SFEMT模型的联合仿真接口。理论分析和实验结果证明了该方法的有效性。

An Interface Method for Co-Simulation of EMT Model and Shifted Frequency EMT Model Based on Estimation of Signal Parameters via Rotational Invariance Techniques

The shifted frequency-based electromagnetic transient (SFEMT) simulation is much more efficient than traditional electromagnetic transient (EMT) simulation for AC grids. This letter proposes a novel interface for the co-simulation of the SFEMT model and the conventional EMT model. The fundamentals of SFEMT modeling are first derived. Then, an interface for the co-simulation of EMT and SFEMT models is proposed based on the estimation of signal parameters via rotational invariance techniques. Theoretical analyses and test results demonstrate the effectiveness of the proposed method.

期刊介绍： The scope of IEEE Transactions on Power Systems covers the education, analysis, operation, planning, and economics of electric generation, transmission, and distribution systems for general industrial, commercial, public, and domestic consumption, including the interaction with multi-energy carriers. The focus of this transactions is the power system from a systems viewpoint instead of components of the system. It has five (5) key areas within its scope with several technical topics within each area. These areas are: (1) Power Engineering Education, (2) Power System Analysis, Computing, and Economics, (3) Power System Dynamic Performance, (4) Power System Operations, and (5) Power System Planning and Implementation.
