Research On Reactive Compensation And Harmonic Suppression Based On APF And SVC

In today's society,with the development of industrial production level,resulting in a lot of power quality problems,which affect the power quality of the two most important is the harmonic pollution and reactive power consumption.Power electronics as the largest harmonic source,in its operation to produce a large number of harmonics,pollution of the power system environment,and also loss of reactive power,reduce the system power factor,affecting the power quality.The main measure in the face of harmonic control is to install the APF on the power supply side,while the static var compensator SVC is an important device to compensate for reactive power.This paper mainly combines the two together to carry out research,so that it can also be in the harmonic suppression of reactive power compensation,greatly play the advantages of the two devices,but also to make up for their own shortcomings,effectively improve the power qualityIn this paper,the status quo of reactive power and harmonics is briefly described.A comprehensive compensation scheme of APF and SVC is proposed,and its background is briefly summarized.Then,the paper describes the active power filter.Then,it discusses the importance of the harmonic current detection technology to APF.Through the introduction of p,q and ip,iq operation mode,the simulation model can be set up,and the results of ip and iq operation are more accurate.In addition,several control methods of APF are also introduced.By comparing the triangular wave comparison method,the validity of the method is verified.Therefore,the triangular wave comparison control is selected in this paper.Then,through the introduction of the static reactive compensator SVC(this article mainly selects the TCR type),discusses the working principle and the connection way of the TCR,and the simulation method of single-phase TCR and three-phase TCR is constructed by using MATLAB simulation technology.Through the comparison and analysis of the two,the reactive power compensation of three-phase TCR is the best.Finally,the active filter APF and static var compensator SVC together,build topology,and simulation technology,build simulation,the APF and SVC can be used to obtain reactive power compensation and harmonic suppression quickly,and the integrated scheme is more efficient and stable,and the efficiency of APF and SVC comprehensive compensation scheme is verified.
