“…to reduce harmonics in its spectrum, the above mentioned technical solutions are used in the area of VSD. One of them is the usage of broadband passive harmonic filter connected to the frequency converter input terminals to compensate a wide spectrum of generated harmonics [4]- [7]. Thus, the content of harmonics is considerably reduced in the current drawn by the drive, resulting in the more favorable current waveform, see Two types of broadband passive harmonic filters with declared values of current THD 10% and 16% have been used for experimental measurements and simulations.…”

Various technical solutions are used to reduce harmonics generated by variable speed drives (VSD). AC VSD belong to their very significant sources with negative influences on the quality of electrical energy at the point of their connection to the network. The paper presents measured results of two types of broadband passive harmonic filters energized from a it programmable three-phase power source Pacific 3120ASX and provides their comparison to the results from a simulation model using EMTP-ATP program. A possibility of applying broadband passive harmonic filter into a structure of a drive of conveyor belt in the coal treatment plant is also shown and compared to the present condition. The results present that the effectiveness of the filters to eliminate harmonics is very good. Nevertheless, it is considerably affected by the quality of supply voltage at the point of filter coupling.Index Terms-Broadband passive harmonic filter, conveyor belt, distortion, harmonics, variable speed drive.

“…The filter should be developed and tested after the filter settings satisfy the performance criteria. The design may be carried out using an analytical formula method or thorough computer simulations of the entire system [19]. Diwan et al described that among the criteria used for performance evaluation may be the current and voltage ratings of each of the filter components and Chosen value of reactive power may be divided by assuming this ratio (1:1:1) i.e., equal reactive power distribution in all filter branches [20].…”

The use of switch mode power supply (SMPS) load such as computer, laptop, etc in residential as well as commercial areas give rise to harmonics pollution in the electrical power distribution system which causes the quality of power poor and the function of equipment connected to the electrical system is affected. Many electrical appliances have an SMPS design that characteristically draws a distorted current that flows back to the input supply and causes distortion in the voltage waveform. To ensure the safe functioning of various electrical devices, there is a need for the implementation of effective harmonics mitigating techniques. Passive filters have been used for mitigating voltage and current harmonics. This paper proposed an analytical approach to designing the passive filter instead of trial and error or a complex approach for harmonics mitigation. The Simulation Model of SMPS is developed in MATLAB/Simulink and used for validating the proposed approach. Simulation results show the attractive findings of the proposed approach for harmonic mitigation with the improvement of the power factor.

“…Filter design should consider economy, technique, safety and other targets, so it is difficult for engineers to design an optimal filter according to the simple engineering experience [5][6][7]. Thus, some scholars suggest multi-objective optimization algorithm should be used to design the power filter by using the computer.…”

For resolving the problem that power filter cannot work normally because TCR (thyristor controlled reactor) generates extra third harmonic current under asymmetrical voltage, the paper proposes the estimation method of current capacity that TCR generates extra third harmonic current under asymmetrical voltage. Considering extra third harmonic current under asymmetrical voltage, Optimum method based on genetic algorithm is used to design the parameters of power filter. With reactive power compensation and harmonic suppression project of a steel mill as example, the proposed method is simulated by Matlab. Simulation results show optimized power filter can eliminate extra third harmonic current effects under asymmetrical voltage, meet the requirement of reactive power compensation, reduce harmonics current that load injects into system, and guarantee the power filter safe operation under asymmetrical voltage.
