Abstract
This paper describes the generation and impact of inverter harmonics and reactive power,and discusses inverter harmonic management techniques and reactive power compensation techniques,including user equipment end-of-pipe management,active management of harmonic sources,passive management of compensation devices,as well as centralised compensation,decentralised compensation,random compensation,follower compensation and tracking compensation.Based on experimental analyses,the utility of harmonic elimination is enhanced so as to improve the safety and efficiency of inverter operation.
