Analysis In The Electric Energy Quality Of Baiyun Airport Power System And Its Solution

In the wake of developments in electric power technology, all kinds of power electronicsequipment and loads input power system, causing enormous power harmonic, effectingquality of electric energy. Besides, increasing precision instrument and digitizer put forwardhigher requirements of the quality of the grid. Therefore, harmonic control has importantsignificance.The subject analyses harmonic of converting stations of Baiyun Airport power system,then chooses navigational lighting aid converting station and terminal’s equipment roomexpressly, which exceeding the national standard of electric power technology. And then ittake steps of controlling harmonic, reducing THD to the standard, eliminating the potentialsafety hazard, at the same time raising the power efficiency and reducing energyconsumption.This thesis analyses causing of power harmonic and its effect generally, explains conceptof power harmonic and its standard, gives a brief analysis of non-sinusoidal wave’s testmethod, and presents suppression measures and AC filter.It analyses harmonic of converting stations of Baiyun Airport power system, and give aproposal of power harmonic, contrasting the effect.It analyses harmonic of Baiyun Airport terminal’s equipment room, and put forward aproposal of power harmonic.
