  • Power control strategy for grid connected permanent magnet synchronous generator of a distributed generation unit

    This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems primary aim is to achieve a low distortion, high ...

  • Cavitation leads to perfect mixes

    Development of accurate classification of cavitation types, as well as any classification, has to be based on a choice of general summary classification signs. For example, it can be different by constructive signs of work parts, by character of a course of process, by cavities types and other general classification signs. In present time distinguish the following types of cavitation: static, ...

  • A binary ACO for controlling all–electric power take off system in wave energy converters

    This paper describes a metaheuristic algorithm for controlling all–electric power take off (PTO) system of wave energy converters. It provides optimal parameter values to the controller following the instantaneously changing sea state. The output of the algorithm is used to tune the electrical control systems in the PTO system in order to provide sufficient time for the point absorber to achieve ...

  • Why it`s time to get serious about wave power

    For most of us power from the sea means watching waves crashing on a beach or smashing up against a breakwater. But if you want to experience wave power at its most energetic then you need to be offshore. In fact you need to be over one hundred kilometres offshore. In February 2000, a British oceanographic research vessel sailing in the Rockall Trough, some 180Km from land, encountered the ...

  • Ships that harvest electrical power from ocean waves

    Electrical power generation from ocean waves is possible from ships that harvests wave energy through daily trips to offshore locations and that return back to port for the delivery of energy to the grid. Energy is stored locally on the vessel during harvesting phase and placed on the grid during periods of high demand (normally mid-day). Unlike conventional wave-power devices, the ships ...

  • Power quality improvements employing multipulse full-wave AC-DC converters

    In this paper, a set of full-wave AC-DC converters are investigated for power quality improvement in AC mains and DC output. A detailed classification of these full-wave AC-DC converter configurations is made in different transformer connections and several new configurations of isolated and non-isolated full-wave AC-DC converters are developed to meet specific application requirements. The ...

  • A novel particle swarm optimisation self-regulating stand-alone wave energy conversion scheme

    The paper presents a novel stabilisation scheme system for a wave energy converter (WEC) using permanent magnet linear generator (PMLG) connected to a six-pulse diode rectifier. The proposed controller of WEC-battery renewable energy system is based on multi-objective particle swarm optimisation (MOPSO) technique. The optimisation algorithm is implemented to control a novel low cost dynamic AC ...

  • Simulation-based evaluation of tidal current power output characteristics

    Tidal current is considered to be one of the promising alternative green energy resources. This paper introduces a simulation based methodology to evaluate tidal current power output characteristics, including capacity factor, and power production variability patterns. Power variability analysis is crucial to grid integration systems design. The proposed methodology is applied to the well known ...

  • Sea For Life developing wave energy absorber

    Sea For Life in Obidos, Portugal, is developing a Wave Energy Gravitational Absorber (WEGA) to extract energy from ocean waves.   Since its origin, Sea For Life has been dedicated to wave energy converters model conception, calculations and project design for construction and laboratory testing of prototypes, having been tested over 15 different models under an electricity production ...

  • An analytical solution and computer simulation for a multi-plate thermoacoustic system

    In this paper, an analytical model for a multi-plate thermoacoustic system is developed. The governing momentum and energy equations are simplified to quasi-one-dimensional forms using reasonable approximations. The expressions for the fluctuating velocity (u1), fluctuating temperature (T1), Nusselt number (Nu), fluid friction irreversibility ...
