The Research Of Harmonic Management Based On Wave Power System

Nowdays,world display a picture that society resource and energy shortage are very obvious,and many countries are battling for energy.In order to alleviate the fierce contradiction and protect earth's enviroment,countries gradually turned to developing all kinds of new energy.Solar energy,wind energy,ocean energy and other clean energy as a key research object by countries.Wave energy is the most abundant energy on the earth,so exploiting wave energy also on the agenda in many coutries.The principle of wave energy power generation is that using wave resonator and hydraulic motor converted wave energy into mechanical energy,then driven generations and converted mechanical energy into electricity providing for island residents and the troops.During this paper,wave power and harmonic control are in same system.They share a set of system,and it can save economic costs of dealing with harmonic in the process of power.Wave power generation system always in the remote island or the sea,and the electricity suppling for resident and military,so the system power grid loads are nonlinear loads such as refrigerators,washing machines,electricfans and radar.There will be several harmoic are creating by many harmonic sources in wave power system.Because of the tradition active power filter ignored harmonic created by the model itself,calculation error,environmental interference and the delay of harmonic,there can not achieve good results of harmonic elimination.So on the basis of the traditional active filter,and based on the instantaneous reactive power theory and fuzzy control theory,then fuzzy control strategy and harmonic carrier way were used,and joined the harmonic error control link,which can better eliminate harmonics.Using MATLAB simulation,and compared to the traditional active filter and the new active filter.Guided by the simulation results,simulating in the laboratory physical platform,however,because of constraints that the results is not as good as the simulation results,but the effect of filter can prove the validity of the scheme.
