Optimal Configruation Of Power Filter In Distribution Network With Multi-harmonic Source

Nowadays, the harmonic pollution problems vast in more prominent cumulativescale and wide distribution in distribution network.This thesis centralized OptimalConfiguration of Power Filter in System levelto solve this problem.First of all, this paper analyses the background of the task, describes theprinciples, means and development of harmonic control in the domestic and foreign.Pointed out the necessity of optimal configuration of power filter in distributionnetwork with multi-harmonic source research.Secondly, this paper discusses the power filter deeply. Combined with theperformance characteristics of various types of filters and the economical ofutilize,choose the single tuned passive filters and the shunt active filter to be the power filterdevicewhich uses in this paper.In addition, the mathematical model of the distributionnetwork of electrical equipment are described.Then the technical characteristics of two types of filters with the currentdistribution network harmonic pollution characteristics combine to delimit the scopeof the two filter their governance, combine to delimit the scope of the two filter theirgovernance, based on this configuration are given two types of filter. Single-tunedfilter using the first network site with the inherent structure theory and then create amathematical model parameter optimization method constant volume configuration,due to its characteristics of shunt active filter with a comprehensive evaluationmethod to configure the program. AFSA and basic improvements were appropriate forsolving the problem of the filter constant volume.Finally, under the Matlab environment, with a18-node network system with anumerical example to verify the effectiveness of the research on power filteroptimalconfigured method.
