Detailed Description Of The Harmonic Energy Consumption Of Pumping Well Grid And Research On The Suppression Method

In this paper,the every harmonic content of pumping Wells in the oilfield power network was analyzed for the influence of active power,to conform to the actual working condition,Fourier analysis method is used to modify the original electrical parameter calculation formula: on the basis of combining with the traditional electric parameter measurement method,Fourier analysis for every harmonic power,accurate analysis and reactive power of calculating every harmonic component,provide theoretical support for fine descriptions of harmonic energy consumption.In the calculation of harmonic energy consumption,the effects of skin effect,proximity effect and steel band protection should be considered.Taking the measured harmonic current content as the reference object,the errors of the measured harmonic current are compared with those of the energy consumption model before and after the correction,so as to verify the accuracy of the calculation model of the modified harmonic energy consumption,and then realize the fine description of the harmonic energy consumption of oil field power grid pumping Wells.Through the calculation of energy consumption of well pumping unit harmonic,and can be more intuitive harmonic energy consumption in the proportion of oilfield network is a representation of the single well,and the determination of harmonic content and harmonic management technology is the guarantee system stability and reduce the energy consumption of oilfield network is necessary condition,therefore the harmonic and harmonic analysis and description of energy consumption and reduce the energy consumption is particularly important.Based on the analysis and prediction of harmonic energy consumption by introducing support vector machine(SVM)algorithm,the harmonic energy consumption of single well can be predicted relatively accurately on the premise of limited data,which provides an effective basis for the production planning of oilfield enterprises.Based on the analysis of the suppression effect of active filter and passive filter,a hybrid filter based on pumping well is improved,which can be used as a harmonic suppression measure.
