Research on Relevance of Electro-power Technology to Harmony-wave Restriction and Minus-power retrieval

The application and development of electro-power technique in the field of electric power system were discussed in the thesis and the harm of upper-harmonious wave was analysed. The conception of minus-power as well as the current status of minus-power retrieval and harmony wave restriction were also studied. It was revealed that electro-power technology was closely related with minus-power retrieval and upper-harmonious wave. After the analysis of passive filtering technology, mechanism and practical application of active filter rejector was elucidated. On the basis of elementary introduction of working feature, systemic struction of power factor correcting unit and new techniques for solving the problems of harmony wave and minus power, the reasonable conclusion was drawn that active filter rejector could cooperate and compensate with the passive filter due to the combined relevant restriction techniques.
