Two‐dimensional analytical model for double field excitation synchronous machines
IET Generation, Transmission & Distribution, 2021 This paper examines a two‐dimensional analytical magnetic model presented for double excitation synchronous machines (DESMs). DESMs employ both permanent magnets (PMs) and excitation coils (ECs), and therefore they offer the advantages of permanent ...

Self-synchronization of Nonidentical Machines in Machine-to-Machine Systems
2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems, 2013 The notion of common time is very important information in distributed systems (e.g., for maintaining the consistency of distributed data). Namely, due to the lack of global time and imperfections (e.g., skew) of physical clocks, in order to agree on common time, distributed nodes have to synchronize themselves.

Analytical Prototype Functions for Flux Linkage Approximation in Synchronous Machines
IEEE Open Journal of the Industrial Electronics Society, 2022 Physically motivated and analytical prototype functions are proposed to approximate the nonlinear flux linkages of nonlinear synchronous machines (SMs) in general; and reluctance synchronous machines (RSMs) and interior permanent magnet synchronous ...

Comparative Evaluation of Dynamic Performance of a Virtual Synchronous Machine and Synchronous Machines [PDF]
IET Conference Proceedings, 2021 Increasing penetration of converter-interfaced renewable generation has led to significant operational challenges for power systems. Such challenges are mainly caused by the different capabilities and dynamic responses of the converters compared with synchronous machines, e.g.
