Abstract:

Efficient and accurate electromagnetic transient (EMT) simulation is the key technology for supporting the operation and control of the power systems. To cope with the contradiction between the speed and accuracy of the traditional EMT simulation, a shifted frequency (SF)-based EMT simulation method was proposed. This paper reviews the key technology of principles for the SF-based EMT simulation and analyzes some existing problems of it. First, the principle of the SF-based EMT simulation is introduced. Then, three key points of the SF-based simulation are analyzed, including the formulation method of a complex signal, the concrete forms of frequency shifting, and the SF-based EMT simulation models as well as their characteristics. Next, the research status of applications for SF-based simulation technology is introduced. Finally, some critical problems in the SF-based EMT simulation are discussed.
