Design Analysis of a Novel Synchronous Generator for Wind Power Generation

Abstract

Abstract:A novel synchronous generator is proposed for wind power generation. The field flux is generated by the half-wave rectified excitation method. The generator does not require slip rings and brushes for field power supply, as well as permanent magnets. In this paper, the excitation method is explained, and then, the basic characteristics are calculated using the finite element method analysis. Furthermore, the generator is designed for increasing the output power and efficiency.

Tuning and Feasibility Analysis of Classical First-Order MIMO Non-Linear Sliding Mode Control Design for Industrial Applications

“…Thanks to the increasing spread and development of performing microprocessors, the computation time of controller processors has been drastically reduced over the past decade, allowing the implementation of more and more complex control architectures. This fact, combined with the current more and more pressing issue of increased efficiency in each industrial field (e.g., in power generation [1][2][3][4], the transport sector [5][6][7], energy utilization [8,9], renewable energy [10][11][12], and so on), strongly favors the development and implementation of more sophisticated control theories, such as model-based ones. Among model-based control techniques experiencing wide popularity, model predictive control (MPC) [13][14][15], feedback linearization (FBL) [16,17], and sliding mode (SM) control [18] stand out.…”

Wind Micro-Turbine Networks for Urban Areas: Optimal Design and Power Scalability of Permanent Magnet Generators

“…With respect to traditional rotors, the asymmetrical one that was proposed in [12] shows similar performance but guarantees, at the same time, reduced maintenance and repair costs. A further original wound field synchronous machine for wind applications is proposed in [13], where the authors presented a half-wave rectified brushless excitation system: in [13] the machine structure recalls that of a conventional salient pole synchronous generator, but the stator slots accommodate both the armature and the excitation windings; moreover, the rotor field winding is short-circuited by a diode, thus the field flux is produced by rectifying the induced voltage through the diode without adopting slip rings.…”
