Commercial Tapered Channel Wave Power Plants in Australia and Indonesia

The article presents the results of studies aimed at improving the power performance indicators of linear electric generators for wave power plants by reducing the flux leakages using high-temperature superconducting (HTS) inserts placed in between the teeth. The generator design involving application of the Vernier principle for magnetic flux modulation with a translator in the form of a hollow cylinder is considered. Generators of this type are used in float wave power plants driven directly by a reciprocating float, which transmits large forces at a low motion speed. The calculations were carried out using the HTS properties modeling procedure based on representing the currents induced in a superconductor in the form of magnetic moments of these currents, which made it possible to simplify the analysis of the electromagnetic field in the generator without significant additional errors. As a result, the characteristics of the electromagnetic force longitudinal components and phase winding flux linkages versus the translator displacement have been obtained. The use of HTS inserts and a distributed winding in the stator made it possible to reduce the electromagnetic leakage losses and increase the interaction force between the stator and translator. However, since the additional outlays for the cooling system and thermal insulation of the HTS elements are commensurable with the generator cost, the obtained results on improving the power performance parameters do not allow an unambiguous statement to be made about the effectiveness of the considered technical solutions.

Piston Mechanism

Pneumatic mechanism widely used in industrial, automotive, aerospace, and etc. The principle of pneumatic like piston is move up and down due to the air pressure inside the piston. Mechanism of piston can be applied to the power plant that utilizes the ocean waves where as use of piston mechanism is very helpful in solving the problem of fossil fuel scarcity as a source of energy in power plants. In this study we will focus on the pneumatic system which utilizing ocean wave that moves longitudinally to encourage buoy that located on the piston shaft to up and down and then the pressing of air out of piston. Output of the piston will be forwarded to the generator (rotor and stator) to produce a voltage. In this paper is focused on the manufacture of pneumatic systems and processes to produce the rotation and voltage. Material of piston tube component made of aluminum and rubber, buoys made of plastic and generator such as of metal and copper coils. Output of the piston will be forwarded to the generator (rotor and stator) to produce a voltage. In this paper is focused on the manufacture of pneumatic systems and processes to obtained the rotation and voltage with aluminum for piston tube material, buoys made of plastic and magnet rotor and copper coils of stator include on the generator and get the results of ocean wave power plant using piston mechanism is 1400 rpm with a voltage of 36 volt.

The Waves

Observations of electric power of the waves hitting beach Tegal is obtained by finding the value of the speed, frequency and height of the waves on the beach Tegal. The average value of the wave velocity of 0.15 m/s, the average frequency of 0.17 Hz and a maximum height of 0.6 m on average. This data is still too low to generate electrical power from the mechanical power of the waves. We are still conducting research to increase the speed and height of the waves with a method of "Tapered Channel". This method is expected to raise the value of the wave height of 0.5 m to 2.2 m. Waves of electrical power is estimated to rise to 15.4 Watt/m2 25-50 Watt/m2.In economic calculation, the power of the waves starting from the value of the wave power per m2 per 4 m2. If we need a 100 Watt power of the waves, the beach area that required 4 m2. Economic development beach with waves generate electrical power, built outside the port area, so that the fishermen keep doing the fishing business as it should be. Based on the results of research in theory, the power of the waves is the speed of the wave function that describes the linear curve. However, the results of research that has been done show that the power of the waves is a function of the speed of the waves, which described as a hyperbolic curve. Wave power increases with increasing speed of the waves. While the formulation used is the wave velocity is a function of the height of the waves. By using the method of "Tepered Channel" to catch a wave, the wave speed will be higher. The results of economic research to generate electrical waves can be calculated byeconomic aspects of the compute power of the waves and technological aspects by counting the frequency of the waves

The Ideal

This paper presents an initial analysis of the technical viability, of the application for the commercial and pre-commercial wave energy technologies, to the Spanish coasts. This analysis provides an optimal framework for future research, choosing one technology and considering a concrete point of the Spanish coast, with their respective constraints such as, the regulatory aspect of the fees to be applied to such technology, and the restrictions related to the protection of the ecosystems, and other local activities not compatible with the technology.This work is continuing the initiative started by the Project Enola. Enola is a software that provides comprehensive and complete information, about the potential electric production, based on wave energy of the Spanish coast. After evaluating all the wave energy technologies available at this point, those more mature and viable have been selected; the parameters under which they are productive have been analysed; and the ideal areas for implementation on the Spanish coast have been determined, according to the potentials provided by Enola and the technical limitations of the technologies themselves. The results is a summary document where one can easily identify the best locations for the deployment of wave power plants (optimum output).
