The Research Of Wave Energy Generating Gevice And Electric Energy Management System

The rapid development of the global economy on energy demand increases ceaselessly,cause natural gas, petroleum and coal resources exacerbated decrease. New energy research,development and utilization of be imperative. Ocean wave energy is a kind of no pollution,energy storage is very abundant renewable energy, earth to Shanghai ocean wave storedelectrical energy can reach5000GW, our country is a big country of ocean, the wave can bevery rich. Wave energy power generation with non-polluting, renewable, reserves and otheradvantages, to solve the increasingly serious energy shortage problem is very important. Thispaper is a new type of floating type wave power device, to the sea buoy lights, coastalresidents and soldiers guarding the island to provide power, and maturity of the technologycan also be realized after large-scale power grid, so it has important theoretical and practicalsignificance. The ocean in the storage of wave energy conversion can be for human use ofelectric energy, the key problem is how to utilize the wave energy power generation. So in thewave power generation system of wave energy conversion device and power conversionapparatus is the focus of the study.The paper firstly introduces the development process of wave energy, wave powergeneration application situation at home and abroad, the wave power is studied. Through theanalysis of the current world all common wave energy conversion device, the permanentmagnetic linear reciprocating generator as a wave energy conversion device, the permanentmagnetic linear generator used in wave power field, the vertical linear reciprocatingmovement of the permanent magnet rotor for generator excitation, can be directly related tothe wave of ups and downs movement characteristics coincide, simplifies the wave energyconversion process, eliminating the various transmission device. Then the research of thepermanent magnetic linear reciprocating generator design method, design a special fourstructures of the linear generator, including the operation of generator parameters andstructure parameters. And the application of Ansoft13software in permanent magnet linearreciprocating generator to generator modeling, model simulation analysis. By modifying themotor parameters for permanent magnet linear generator is optimized, the main parametersincluding the motor pole pairs, permanent magnet size, number of stator slots, the number ofwinding turns, determined the permanent-magnet linear generator design. Then the paper described by a three-phase bridge rectifier circuit, Buck-Boost circuit andbidirectional Buck/Boost conversion circuit of power converter. When the wave effect,permanent magnet linear generator for converting frequency amplitude instability of ACpower, electric energy conversion device in the instability of the alternating current isconverted to a stable DC power for loads and charging to the standby battery; when the seawhen be in smooth water, permanent-magnet linear generator power or a voltage insufficient,by batteries through the bidirectional Buck/Boost converter circuit to supply power to theload. And then on the Buck-Boost conversion circuit, a bidirectional Buck/Boost convertercircuit is presented to determine the control method, and the application of Matlab toBuck-Boost converter control system and battery charge and discharge control systemsimulation. Then complete the power conversion device is designed, including hardwarecircuit and software structures.Finally the paper tells the story of the completed permanent-magnet linear generatorphysical, electrical energy management system design based on Simulation and experimentanalysis, the whole wave energy power generation system design scheme is correct andfeasible.
