MATLAB simulation of harmonic suppression and reactive power compensation in power supply system
Abstract：The wide application of nonlinear loads to the power grid brought serious harmonic pollution, and thus produced a series of power quality problems, and all kinds of sensitive load on the grid power quality put forward higher requirements.
In this paper, the design method of the passive power filter is studied.. With analysis of various types of passive power filter structure and working principle of and on the basis of the relevant parameters affecting the performance of the filters were analyzed, focusing on the equivalent frequency deviation, quality factor, no reactive compensation capacity and system harmonic impedance of single tuned filter and high pass filter (HPF) effect. As the theoretical basis of the design of filtering device, it provides the theoretical criteria for engineering design..
The passive filter device for power system. In the conventional tuned filter design, considering the actual filter influenced by the power grid load and its characteristics of the element, in the presence of detuning, take the best tuning method of single tuned filter design. In the capacity for a given, the tuning, experience partial tuning and the best tuning design calculation is carried out, results, it is concluded that the best harmonious design income relatively smaller capacity harmonic filtering ability better advantages.
