The Wind Energy is one of the cleanest sources of electrical energy. Commercial wind turbines deliver the promise of being practically realizable with the cost of having an extremely large footprint and being haunted by the Betz Limit. This paper gives an idea of Direct Wind to Energy Conversion which aims to produce electrical energy by harnessing wind’s kinetic energy, devoid of any rotational mechanism. The method in question utilizes the technique of Electro-Hydro-Dynamic Atomization (EHDA) to atomize charged working fluid to deposit its particles on collector electrodes using wind as a carrier. A comparative analysis of several working fluids was conducted to optimize energy production. Simulations on the charged particle trajectory were conducted based on historical average wind speed values to enhance electrode placement which in turn led to design iterations and increased efficiency.

“…Since an offshore wind farm mostly uses High Voltage Direct Current (HVDC) to transmit power efficiently, the proposed generator eliminated the need for an AC to DC converter, since the electricity generated was DC. In a more recent technique from 2005 [5], Djairam, Hubacz, Morshuis, Marijnissen, Smit, in harvesting the wind energy, used an electrostatic wind converter (EWICON) instead of the traditional wind generator. EWICON generates the electrical power by forcing the charges to move in the opposite direction of the electric field by the wind to increase the energy of the system.…”

“…The proposed SEG can play a significant role in the renewable power sector as well. In fact, the proposed SEG can function as a high-voltage source, which is required by the electrostatic wind energy converter (EWICON) as in Reference [5]. For example, instead of connecting EWICON directly to a high-voltage source, it can be connected to a low-voltage source with SEG, which in turn can generate the high voltage required by the generator.…”

A Novel Design of Static Electrostatic Generator for High Voltage Low Power Applications Based on Electric Field Manipulation by Area Geometric Difference

An electrostatic generator is an electromechanical device that produces static charges at high voltage and low current. This technology is mature enough, as it has existed for many centuries. Nevertheless, the working principle of most of the commonly used electrostatic generators is still based on typical mechanical methods, which consequently makes them bulky and limits their controllability on the generated charges, e.g., Van de Graaff generator that uses the friction between two different materials to generate electrostatic charges. In this paper, a novel design of a static electrostatic generator (SEG) is presented based on a completely different idea compared to existing electrostatic generators, which offers several potential benefits. The idea originates from the study of a parallel plates capacitor—for instance, if a voltage is applied to two plates of a capacitor, then according to Gauss’s law, both of the plates must have an equal and opposite charge. Suppose one of the plates has a different geometry, with a shorter length than the other, then the number of the charges on both plates will not be equal. Thus, by manipulating the geometrical area of the device, a different number of charges will be generated on both metal conductors. Therefore, a different number of charges are generated on both conductors; hence, by connecting both conductor plates of the capacitance, excess charges will remain on the device. The proposed idea was assessed with computer simulations using finite element and finite difference methods for a variety of different scenarios to determine the optimal design of the proposed device. The device offers several advantages over traditional electrostatic generators, such as that it can generate either positive or negative charges by merely reversing the polarity of the DC source; additionally, it is very simple, lightweight, and easy to manufacture. In particular, the principal advantage of the proposed device is that it is a static one, and no mechanical movement is required to produce charges. Further, the design is general enough and scalable. The simulation results demonstrate the performance of the proposed device.

High-power direct-driven permanent magnet wind generators (HDPMWGs) are characterized by their low speed, large number of pole-pairs, and considerable usage of permanent magnet (PM) material. Therefore, the cost of the HDPMWGs is higher than that of their counterparts. Based on the analysis of MMF contents of integral-slot windings and fractional-slot windings, the paper proposes a material-saving technique for HDPMWGs. By employing concentrated integral-slot windings, increased number of turns per phase, and rotor pole shift or step skewing, the optimized design reduces the amount of electromagnetic material being used, especially the expensive PM materials, without significantly impacting the performance and manufacture procedure of HDPMWGs. The techniques presented in this paper servers as a useful guideline for material-saving optimization of HDPMWGs.
