THE GENERAL CONTROL STRATEGYFOR HARMONIC ELIMINATION,REACTIVE POWERCOMPENSATION AND ASYMMETRICALLOAD BALANCE (Ⅰ)

本文对瞬时实功率和虚功率的频谱特性进行了分析，得出了瞬时实功率、虚功率的频谱特性与负载电流中的无功分量、谐波分量、不对称分量的对应关系。在此基础上，就可以建立满足各种条件下系统的谐波抑制、无功补偿及不对称负载平衡衡量化的统一控制策略。

お? This paper gives an analysis of the spectrum of instantaneous active and reactive power in a power system.The analysis shows that there are relations between this spectrum and components of the harmonic,reactive power,negative sequence and zero sequence power.Based on these relations,a general control strategy for harmonic elimination,reactive power compensation and asymmetrical load balance can be devised.
