Abstract


With the increasingly depletion of non- renewable energy energy crisis Daywork can be , a new energy research , development and use of the imperative . Wave energy does not produce any pollution renewable clean energy , inexhaustible, inexhaustible . Wave power reserves , renewable , non-polluting , nearby development and utilization of the advantages of China is a maritime country , can take advantage of the waves is extremely rich . This study is a new type of floating - linear waves generator to provide electricity to the maritime beacon lights, coastal residents , the residents of the island or the People's Liberation Army soldiers guarding the island , when the technology is mature , large-scale grid , so it has important theoretical and practical significance. Floating wave generator design , the size of the power generator sets to determine where sea waves . The floating wave generator force device floats, its size should be determined by the waves . Waves can be fully absorbed and used floats force to establish a mathematical model to analyze the given average wave height and frequency of the wave action , the size and quality of the buoy correspondence between motor power . And use of SIMULINK simulation on the the buoy displacement of the motor output power , in order to determine the size of the floats , quality , as well as the power of the motor , so that it can fully absorb the waves . The birth of the new permanent magnetic materials , permanent magnet motor performance has been greatly improved . The permanent magnet motor used in the field of wave power , the use of the permanent magnets of the linear reciprocating motion of the upright as a generator excitation transducer can directly with the waves of the undulating movement characteristics coincide simplify the wave energy conversion process , eliminating the need for a variety of transmission , permanent magnet linear motor is a good choice for innovative traditional wave power generation system . In this paper, a special surrounded the structure of permanent magnet linear generator , numerical calculations and finite element analysis of the electromagnetic field using ANSOFT Software , and simulate the performance parameters of the rated running state . According to the simulation results, the motor structure to be modified , reducing the vibration of the motor , so that the generator performance optimization .
