Design and Analysis of a Dual‐Direction Hybrid Excitation Generator
IEEJ Transactions on Electrical and Electronic Engineering, 2022With the wide use of new energy vehicles, the research and development of high‐performance generators become more important. The claw pole machine is very suitable to be used as an automobile generator because of its unique characteristics. However, its development is limited by the disadvantage of abundant harmonic content, especially when used with ...

Robust control of hybrid excitation synchronous generator for wind applications
Mathematics and Computers in Simulation, 2017The purpose of this paper is to develop a robust control law for a hybrid excitation synchronous generator (HESG) for wind power applications. In a HESG, the excitation flux is created by both permanent magnets and excitation coils, so the output voltage can be controlled by the DC excitation field. For isolated loads, it is then possible to use a very

Simulation of AC excitation field orientation control for hybrid excitation synchronous generator
Proceedings of 2013 2nd International Conference on Measurement, Information and Control, 2013A novel coordinate structure hybrid excitation synchronous generator (HESG) with AC excitation is proposed to solve the problem that the air-gap magnetic field of permanent magnet synchronous generator (PMSG) is not easy to control. The structure and operation principle of the HESG are presented.

Hybrid excitation of synchronous generators for wind turbines
2nd IET Renewable Power Generation Conference (RPG 2013), 2013A simplified hybrid PM- and electrically excited synchronous generator model is introduced. A 3MW direct-drive wind turbine Cost of Energy model is used to show how magnet costs can make hybrid or fully electrically-excited synchronous machines economically attractive.

Self-excitation characteristics of a hybrid excitation single-phase synchronous generator
2008 18th International Conference on Electrical Machines, 2008This paper describes the self-excitation characteristics of a hybrid excitation single-phase synchronous generator with the features of both wound-rotor and PM synchronous machines. The wound field provides field regulation and allows the field-strengthening operation.

Energy-based hybrid excitation control for synchronous generators
IEEE PES General Meeting, 2010This paper presents an energy-based hybrid control, which replaces the traditional automatic voltage regulator (AVR) for excitation control of a synchronous generator connected to an infinite power system. The proposed controller is based on energy representation of the power system by using a port-controlled Hamiltonian form.

Hybrid excitation synchronous generators for small hydropower plants
2016 XXII International Conference on Electrical Machines (ICEM), 2016Modern rare-earth permanent magnets (PMs) can substantially improve the output characteristics of electrical machines. However, at the same time, the main flux created by PMs is not adjustable, and therefore, permanent magnet synchronous generators (PMSGs) are inappropriate for some applications where the reactive power regulation is required.
