The study of energy metering containing harmonic source branch based on equivalent power factor method

SUN Ming,ZHANG Wei,ZHANG Shu-jian,MA Juan(School Electric Engineering and Automation,Hefei University of Technology,Hefei 230009,China)  
The paper theoretically analyzes the influence of harmonic sources on electric energy metering,and validates them through simulation experiments.At the same time,according to the power factor approaches for tariff adjustment,it proposes the method of power measurement based on the combination of fundamental power factor and equivalent power factor.And it discusses respectively the power measurement methods on the system,linear load and nonlinear load.It is concluded that based on the fundamental power measurement,the tariff of the non-linear user should adjusted according to the equivalent power factor,and tariff for the system and linear load customers are still adjusted according to the fundamental power factor.
