Research on Harmonic Energy Measurement Method of Electric Energy Measurement Instruments
With the continuous addition of power electronic equipment to the power grid,there are more and more harmonic components in the power system,and the harm of harmonic pollution to the power grid is more and more serious.However,the traditional power meter only measures the fundamental wave power component,but does not consider the harmonic energy,which leads to the measurement of the power meter is less than the real power con-sumption.Therefore,harmonic energy is harmful to the power grid,not only the penalty measures,even do not have to pay the electricity fee,further leading to the increase of harmonic energy,harm the power grid.This paper puts forward a measuring method of power meter that takes harmonic energy into account,which can measure fundamen-tal and harmonic energy.By increasing the weight value of fundamental and harmonic energy cost,it can motivate users to reduce the consumption of harmonic energy,so as to achieve the purpose of controlling harmonic component of power grid.In order to verify the algorithm proposed in this paper,combined with the actual project,verify the ac-curacy of the electric energy meter using the algorithm to measure the electric energy.
