TL;DR: In this article, a wave power generator is provided to enable power generation to be continuously performed since a rotary blade rotates a power generating shaft by the vertical movement of the wave and at least one rotary blades rotates while the wave rises.
Abstract: PURPOSE: A wave power generator is provided to enable power generation to be continuously performed since a rotary blade rotates a power generating shaft by the vertical movement of the wave and at least one rotary blade rotates while the wave rises. CONSTITUTION: A wave power generator comprises a main body(2), floating tanks(4) and a plurality of rotary blades(5). The main body comprises a power generating shaft and is horizontally installed. The floating tanks are respectively connected to both ends of the main body and are floated by the buoyancy. A generator(3), which is connected to the power generating shaft, is installed in any one of the floating tanks. The rotary blades rotate by the vertical movement of the wave only in one direction. The rotary blades are alternately installed on the upper part and the lower part of the main body at given intervals.

TL;DR: In this article, an array wave power generating device which comprises a plurality of floats, elastic connecting pieces, piezodielectric elements, and rectifier filters is presented, and the size of the array is changeable according to the requirements of generated power.
Abstract: The invention discloses an array wave power generating device which comprises a plurality of floats (1), a plurality of elastic connecting pieces (3), a plurality of piezodielectric elements (4) and a plurality of rectifier filters, wherein the floats (1) are mutually connected through the elastic connecting pieces (3) to form a float array, and the size of the array is changeable and determined according to the requirements of generated power. The device has the advantages of novel design, unique structure, broad adaptability, low installation cost, long service life, high reliability and convenience in maintenance; by adopting the floating array structure, the device is easy to deploy, free from the limitation of size of the waves, and high in electromechanical conversion efficiency; and the device can also be used as a hydroelectric power generation device or a wind power generation device, and also has obvious advantages by being compared with the traditional hydroelectric power and wind power generation technologies.

TL;DR: In this article, the authors proposed a wave power station with at least one swinging lever and at least two additional flow energy converters, by which the inherent flow energy of the water located in the wave passage is constantly extracted.
Abstract: The device described contains at least one swinging lever (4) provided with a floating body (5) and articulated so as to be able to swing in the vertical plane on a main body (3) anchored in the water and, if desired, floating. Between each swinging lever (4) and the main body (3) is a piston/cylinder arrangement (6) to supply a pressure medium preferably directly into a pressure accumulator. The compressed pressure medium is decompressed in a turbine or in a hydraulic engine and the drive shaft of said turbine or engine is connected to a generator to produce electricity. It is proposed that at least on each floating body (5) at least one additional flow energy converter (7) is provided by which also the inherent flow energy of the water located in the wave passage is constantly extracted. Preferably several such devices can be linked with an on-shore power station by means of power and control cables, and economically and reliably operating wave power stations can thus be set up.

TL;DR: In this paper, a prototype wave map is presented which features wave power variability as a central figure of merit in the search for suitable wave energy sites. But, the coefficient of variability is introduced as a key metric in particular, since significant variation above the mean power will have implications for system rating and capacity and the capability to withstand high loads.
Abstract: Traditionally, sea areas with a high mean wave power, ideally situated close to population centres, are seen as the most viable for harnessing economic wave energy. However, wave energy variability is a key driver of cost, since significant variation above the mean power will have implications for system rating and capacity and the capability to withstand high loads. Conversely, significant variation below the mean with result in ineffective power conversion, due to the robust nature of a wave energy converter with an ability to deal with high loads. Additional benefits of low power variability include smoother power production and increased value of generated electrical power. This paper demonstrated a prototype wave map which features wave power variability as a central figure of merit in the search for suitable wave energy sites. In particular, the coefficient of variability is introduced as a key metric. An on-line prototype map has been developed with a range of key information provided at a number of locations at which data was made available.
