“…The adaptive frequency shifting of the Fourier spectrum of analytic signals that describe the transients under study is achieved, leading to the method frequency‐adaptive simulation of transients (FASTs) . The FAST‐based multi‐scale transient models of distributed‐parameter transmission line and synchronous machinery were developed in the works of Gao and Strunz, and Ye et al . The SFA and FAST are mainly applied in the alternating current (AC) power system that contains a fundamental frequency of typical 50 or 60 Hz.…”

In a wind energy conversion system (WECS), multiple-time-scale transients that cover a wide frequency range from low-frequency transient stability up to high-frequency switching events are observed. This paper presents a methodology of modeling diverse transients for a permanent magnet synchronous generator (PMSG)-based WECS within the same study. Multiple physical areas of the PMSG-based WECS are given depending on the appearance of carriers contained in the considered waveforms. In order to eliminate different carrier frequencies, the PMSG and generator-side voltage source converter (VSC) are modeled in the dq0-reference frame. On the other hand, the grid-side VSC and utility grid are dealt with in the multi-scale model of the network in which the shift frequency is available. The switching-function and average-value models of the VSC are selected depending on the carrier shifted. In addition, interface between the control and electrical subsystems is redesigned to offset the computation error caused by one time-step delay. Two test cases are performed to study the wind power fluctuations and faults ride-through. The results show that the proposed multi-scale model is able to simulate slow-changing dynamic responses up to high-frequency transients accurately while decreasing the simulation burden. In comparison with the results obtained from the EMTP (electromagnetic transients program) type simulators, the effectiveness and accuracy of the multi-scale model are verified.

“…The multi-scale PD machine model [12] maintains high efficiency over the EMTP-type PD model when slow transients are emulated. In spite of this, the self and mutual inductances of the PD machine model are time-varying.…”

A dq0-domain synchronous machine model that is aimed at accurate and efficient simulation of electromagnetic and electromechanical transients in power electric networks is developed. The electromagnetic part of the machine model is derived firstly in the dq0 reference frame. Then, imaginary parts for the dq quantities are constructed to ensure the compatibility with external multi-scale network model. Finally, a multiscale companion model of synchronous machine is established to simulate diverse transients. The first benchmark case for subsynchronous resonance studies is studied, and a comparison of the results with those obtained from EMTP-type simulator verifies the accuracy and efficiency of the proposed machine model.
